Embodiments of the present application are described below with reference to the accompanying drawings. As one of ordinary skill in the art can know, with the development of technology and the appearance of new scenes, the technical scheme provided by the embodiment of the application is also applicable to similar technical problems.

The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely illustrative of the manner in which embodiments of the application have been described in connection with the description of the objects having the same attributes. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

In order to solve the above problems, the embodiment of the present application provides a data transmission scheduling method. The following describes the data transmission scheduling method according to the embodiment of the present application in detail with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a flow chart of a data transmission scheduling method according to a first embodiment of the present application, which can be applied to a terminal device having at least one network communication device, such as a notebook computer, a desktop computer, a vehicle-mounted terminal, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a robot, or the like, and the application does not limit the product form of the terminal device. The network communication device can comprise network cards corresponding to different types of networks, and can comprise a wireless network card supporting a mobile network, such as a GPRS (general packet radio service) network card and a CDMA (code division multiple access) network card, a wireless network card supporting a wireless local area network (Wireless Local Area Network, WLAN), wherein the network card can realize wireless connection through a WIFI standard, and a wireless network card supporting an Ethernet (Ethernet) so as to meet the requirement of high-speed data transmission.

Based on this, as shown in fig. 1, the data transmission scheduling method proposed in this embodiment may include, but is not limited to:

Step S11, responding to a data transmission scheduling request of a first service and a second service operated by the electronic equipment, and adjusting the data transmission rate of the second service in the system kernel of the electronic equipment based on the time delay information of the first service;

In the embodiment of the application, the second service refers to at least one type of service with a lower scheduling priority than the first service, wherein the higher the scheduling priority is, the higher the data transmission rate requirement on the corresponding service is, the faster and more complete transmission of the corresponding data is required to be realized for the corresponding service, the response efficiency of the service is improved, the delay information is reduced, the response timeliness requirement of the corresponding service is better met, and the access experience of the user to the service is improved.

Based on this, the first service may be a foreground application (Foreground Application) that is more focused on user interaction and response speed, may be an application program or command that is currently being executed by the terminal device and directly interacts with the user, and the user inputs a command at the terminal device, and the first service may immediately respond to and display an output result, such as an interactive application of a game, a video conference, a browser, instant messaging software, or other social software, and the like. It can be seen that the various applications contained in the first service typically have a graphical user interface (GRAPHICAL USER INTERFACE, GUI, which may be referred to as a graphical user interface) whereby the user is directly interacted with, data is presented and an interactive experience is provided, and the application is not limited to the type of application contained in the first service.

The second service may be a background application (Background Application) that may be independently executed in the terminal device without user interaction, that is, a program or command executed in the background of the terminal device, and the user may continue to use the terminal device to execute other operations while executing the background task, with respect to the first service described above. It can be seen that the second service may include an application/service that performs tasks that need to run for a long time or do not want to occupy foreground interaction, such as a background application that performs network activities of downloading/uploading data, etc., and the present application does not limit the types of applications/services that the second service includes.

Therefore, in order to improve user experience, under the condition that the terminal equipment simultaneously operates the first service and the second service, the application can preferentially ensure the response speed of the first service, avoid delay, display picture/interactive operation blocking and the like of the first service, and under the condition that the same network communication equipment of the first service and the second service sharing electronic equipment carries out data transmission with corresponding external equipment, the limited communication resources of the network communication equipment can be preferentially scheduled to the first service so as to ensure the response speed of the first service, and meanwhile, the application can also schedule the communication resources required by supporting the operation of the second service, such as the minimum communication resources supporting the normal operation of the second service and the like, ensure that the communication resources are scheduled for the first service and the communication resources which are allocated to the second service are remained to support the normal operation of the second service.

Based on the above, in the process of responding to the data transmission scheduling request for the first service and the second service, in order to ensure the response speed of the first service and the normal operation of the second service, and to request to schedule the communication resources of the same network communication equipment to which the first service and the second service are respectively allocated, so as to adjust the respective data transmission conditions of the two services, the application proposes to implement by adjusting the data transmission rate. The application does not limit the realization method for adjusting the data transmission rate of the second service.

In the embodiment of the application, the time delay information of the first service can be used as the performance index of the data network transmission of the first service operated by the electronic equipment, and the real-time performance and the efficiency of the data transmission of the first service are represented. Since the delay information refers to Round-Trip Time (RTT), that is, indicates the total Time elapsed for the electronic device to receive the response data, from the electronic device (which may be a transmitting end) to transmit the request transmission data from the first service to the corresponding external device (which may be a receiving end), to the external device in response to the received request transmission data, the response data thus generated is fed back to the electronic device. Visible. With the change of network transmission performance between the electronic equipment and the external equipment, the time delay information of the first service can be correspondingly changed.

Step S12, controlling the same network communication equipment to receive respective response data for the first service and the second service based on the adjusted data transmission rate through a system kernel;

In combination with the related description of the delay information of the first service, for the data transmission process between the electronic device and the external device, the delay of sending data of the first service request in the electronic device can be reduced, and the data can be timely sent to the external device, so that the external device can feed back corresponding response data as soon as possible, the purpose of reducing the delay information of the first service is achieved, the queuing delay of the first service in a network can be reduced by timely receiving the response data of the external device for the first service, the purpose of reducing the delay information of the first service is achieved, and in order to improve the adjustment efficiency of the delay information of the first service, the data transmission scheduling method provided by the embodiment of the application can be realized according to the sending delay and the queuing delay of the two modes.

Based on the above, in order to reduce queuing delay of response data for the first service, timely and reliably receive response data required by the operation of the first service from the external device, the scheduling of response data required by each of the first service and the second service can be implemented according to a received data scheduling rule configured by a system kernel and specific to a response data receiving process. According to the analysis, the received data scheduling rule in the embodiment of the present application may represent a rule for adjusting the data transmission rate of the second service based on the delay information of the first service, and the content of the present application is not limited. It should be understood that the data transmission rate refers to a data reception rate at which the system core receives response data for the second service transmitted by the network communication device.

In general, for the communication resource of the same network communication device shared by the first service and the second service, the present application configures different data transmission channels for the network communication device to realize data transmission in different directions, that is, receives response data from an external device through a data receiving channel, and sends request sending data from each service to the external device through a data sending channel. Based on this, in the practical application of the present application, for the process of receiving response data for different services by sharing one data receiving channel, the size of the data receiving resource allocated for each service directly affects the receiving speed and the integrity of the response data for the corresponding service, thereby affecting the response speed and the delay information of the corresponding service.

In the case that the data receiving resources configured by the data receiving channel are basically fixed, for a plurality of services sharing response data required for transmission of the data receiving channel, such as the first service and the second service, the data receiving resources allocated to one part of the services are increased, and the data receiving resources allocated to the other part of the services are correspondingly reduced, so that the response speed of each service is affected.

Based on this, in the case that the scheduling of the data receiving resources of each service sharing one network communication device is achieved by adjusting the data transmission rate of the service, so as to achieve the data transmission rate and the integrity of each service, in order to adjust the delay information of the first service, the experience of the user in using the first service is improved, and the second service is prevented from stopping running, the embodiment of the application proposes to achieve the adjustment of the data transmission rate of the second service. In this way, in the response data scheduling process (response data scheduling process for transmitting data to the data receiving channel) of the first service and the second service based on the received data scheduling rule configured by the system kernel, after the data transmission rate configured by the system kernel for the second service is adjusted, the communication resources of the network communication device allocated for the second service are correspondingly changed, and meanwhile, the communication resources of the network communication device allocated for the first service are changed, and the receiving conditions of the corresponding response data are supported by the communication resources after the change allocated for each of the first service and the second service are different, so that the respective data transmission scheduling of the first service and the second service is realized.

For example, the bandwidth of a network communication device shared by a foreground application and a background application of a current terminal device is 10M (the bandwidth width is 10 megameters, which represents the data transmission rate), if the background application downloads, the current data transmission rate (the network speed) is 10MB/s, and the bandwidth is occupied by the background, so that the time delay of the foreground application is very large, the jamming is obvious, and the user experience is poor. If the data transmission rate of the background application is adjusted to be 1MB/s, the communication resources allocated to the background application at the same time are reduced, the communication resources allocated to the foreground application are increased, 9MB is reserved for the foreground application, the response speed of the foreground application is improved, the foreground application is enabled to run smoothly, the user experience is improved, meanwhile, the background application can not stop interaction on the service, and the downloading can still be continued.

In the embodiment of the application, the external devices of the response data required by the first service and the second service running for the electronic device can comprise different response devices corresponding to the services, such as a communication server or a service server for providing interactive service for interactive application, a data source for providing download data for background application or a database/platform for receiving uploading data, and the like. For the device types of the first response device for the first service and the second response device for the second service, and the data response implementation method, the external device supporting the service and the service principle of the service can be determined according to factors such as the service type executed by the corresponding service, and the application does not detail the device types of the response devices and the implementation process of providing the corresponding service for the corresponding service.

And step S13, responding to the data transmission requests of the first service and the second service, and controlling the network communication equipment to sequentially transmit the request transmission data from the service belonging to the corresponding scheduling priority by the system kernel based on the scheduling priority of the first service and the second service.

The analysis is followed to reduce the effect of the delay information of the first service by reducing the transmission delay of the request to transmit data by further including the transmission time of the request to transmit data from the first service. Therefore, the system kernel of the electronic equipment is configured with the transmission data scheduling rule aiming at the data transmission process, thereby realizing the scheduling of the request transmission data of each service according to the transmission data scheduling rule for each service of the data transmission channel of the same network communication equipment, preferentially scheduling and transmitting the request transmission data of the service with high response speed (such as the first service) and reducing the delay information of the service.

Based on the above, in order to implement the above-mentioned transmission data scheduling rule and reception data scheduling priority, in combination with the requirements of response speed, time delay, etc. for each service, the scheduling priority to which each service belongs is configured, and then the scheduling priority of the first service is made higher than the scheduling priority of the second service. In this way, in the process of responding to the respective data transmission requests of the first service and the second service operated by the electronic device, in order to reduce the transmission delay of the request for transmitting data of the first service and improve the delay condition of the first service, the embodiment of the application proposes that the system kernel determines the transmission sequence of the request for transmitting data from the first service and the request for transmitting data from the second service based on the respective scheduling priorities of the first service and the second service, thereby controlling the network communication devices shared by the two types of services to sequentially transmit the request for transmitting data corresponding to the scheduling priorities.

In this way, if the system kernel receives the request transmission data from the first service and the request transmission data from the second service under the condition that the delay information of the first service needs to be reduced, according to the transmission data scheduling rule provided by the embodiment of the application, the request transmission data from the first service is preferentially transmitted, so that the corresponding external device can receive the request transmission data of the first service as early as possible, the generated response data is fed back to the electronic device as early as possible, and the round trip time rtt instant delay information of the first service in the communication process of the electronic device and the external device is reduced.

Therefore, in the embodiment of the application, the time delay information of the first service operated by the electronic equipment can be changed based on the transmission control of the request for transmitting data of the first service and the receiving control of the response data correspondingly generated, when the time delay information of the first service needs to be improved, the experience of a user on the first service is improved, on the one hand, the data transmission rate aiming at the second service in the system core is adjusted based on the time delay information of the current first service, so that the system core controls the same network communication equipment to receive the response data aiming at the first service and the second service respectively, thereby achieving the aim of reducing the queuing time delay of the response data aiming at the first service, on the other hand, in the process of responding to the data transmission request, the system core is controlled to sequentially transmit the request transmission data from the service belonging to the corresponding scheduling priority, thus the network communication equipment can be controlled to transmit the request transmission data of the first service with higher scheduling priority preferentially, the purpose of reducing the transmission time delay aiming at the request transmission data of the first service is achieved, on the other hand, the time delay of the request for transmitting the response data required by the first service and the request transmission data of the second service can be reduced, the time delay of the two parts of the request transmission data can be controlled rapidly, the service can be reduced, the application is realized, and the communication resources of the communication equipment can be shared, and the communication equipment can be guaranteed at the same time, and the time delay is reduced.

In addition, the application is not limited to the network type supported by the network communication equipment shared by the first service and the second service, and can be a WIFI network, a mobile network, an ethernet network or the like, which are all suitable for the data transmission scheduling method provided by the embodiment of the application, and the implementation process is similar, and the application is not described in detail.

It should be noted that, under the condition that the data sending channel and the data receiving channel in the same network communication device shared by multiple services operated by the electronic device respectively implement an external sending process of requesting to send data and a receiving process of receiving response data from the external device, in a data transmission scheduling process of each service, the system kernel may also flexibly select one or two of the configured sending data scheduling rule and receiving data scheduling rule according to the respective available communication resource duty ratio of the data sending channel and the data receiving channel, that is, select to implement scheduling of requesting to send data of the first service and the second service, and/or implement scheduling of response data for the first service and the second service, so as to achieve the purposes of improving the response speed of the first service and avoiding the stop operation of the second service.

Based on the above, under the condition that the data transmission resources of the data transmission channel are sufficient, the data transmission resources of the network communication equipment meet the respective data transmission requests of the first service and the second service, the network communication equipment can be controlled by the system kernel to simultaneously transmit the respective request transmission data from the first service and the second service, and the control mode does not influence the response speed of the first service. Accordingly, in the case that the data transmission resources of the data transmission channel are insufficient, that is, it is determined that the data transmission resources of the network communication device do not meet the data transmission requests of the first service and the second service, step S13 may be executed, the data transmission rate and the transmission data integrity of the second service may be sacrificed, the low-delay operation requirement of the first service may be preferentially met, and the second service may not be prevented from stopping operation, thereby meeting the operation requirement of the second service.

Referring to fig. 2, a flowchart of a data transmission scheduling method according to a second embodiment of the present application may describe an optional refinement implementation method of the data transmission scheduling method according to the foregoing embodiment, as shown in fig. 2, the refinement implementation method may include:

step S21, obtaining time delay information of a first service operated by the electronic equipment;

in combination with the related description of the delay information in the above embodiment, the response speed of the first service operated by the current electronic device, such as smoothness of the online game operated and response speed to the input operation, may be used to obtain the delay information of the specified first service by using a kernel mechanism supported by the operating system of the electronic device.

In one possible implementation, in response to a delay acquisition request for a first service operated by the electronic device, a communication message sent by a system kernel of the electronic device is received, where the communication message may include delay information of the first service determined by the system kernel, where the delay information is determined based on a sending time of a request for sending data of the first service and a receiving time of response data generated correspondingly as described above, and then the communication message may be parsed to obtain current delay information of the first service.

Based on this, under the condition that the Linux operating system is configured by the electronic device, in combination with the system architecture schematic diagram shown in fig. 3, a request can be sent from the protocol stack by using sockdiag supported by Linux, for example, a netlink socket is created, a request message is constructed, which can include an object and a condition for implementing the request, for example, under the condition that the delay information of the current first service is detected, the system kernel can also be requested to detect the delay information of the first service, the delay information detection mode or the statistical mode is recorded in the constructed request message, the system kernel fills in a corresponding field of the request message after detecting the delay information of the current first service according to the delay information, and reports the request to the system service requesting to acquire the delay information of the first service through the netlink message, so that the system service can analyze the delay information of the first service from the request.

It should be noted that, the method for acquiring the delay information about the first service includes, but is not limited to, the implementation manner described above, and in the case that the electronic device configures other types of operating systems, the implementing process of the present application is not described in detail, and may also be according to a kernel mechanism supported by the operating system, and the implemented communication method between the user space program and the system kernel acquires the delay information about the first service detected by the system kernel.

Step S22, if the time delay information meets the data transmission scheduling condition for the first service, determining that the electronic equipment operates a second service with a scheduling priority lower than that of the first service, and responding to the data transmission scheduling request for the first service and the second service;

Step S23, based on the time delay information of the first service, adjusting the data transmission rate of the second service in the system kernel of the electronic equipment;

In the embodiment of the application, the data transmission scheduling condition aiming at the first service indicates that the time delay information of the first service is overlarge/smaller, and the data transmission scheduling of the first service and the second service operated by the electronic equipment is required to meet the judging condition of the respective operation requirements of the first service and the second service, so that the content of the data scheduling condition can be flexibly configured according to the performance requirements such as the response speed of the actual first service, and the content of the data scheduling condition aiming at the first service can be correspondingly adjusted after the performance requirements of the user on the first service are changed, thereby realizing the implementation method without limitation.

If it is determined that the delay information of the first service meets the data transmission scheduling condition for the first service, it is indicated that the delay information of the first service needs to be adjusted currently, and if at this time, the electronic device operates at least one type of service with a scheduling priority lower than that of the first service in addition to the first service, and records the service as a second service, and in combination with the above description of the technical concept of the present application, the embodiments of the present application propose to implement data transmission scheduling for the first service and the second service by adjusting the data transmission rate for the second service.

When the data transmission rate of the second service is adjusted, the data transmission rate of the second service is adjusted according to different time delay information of the first service, the data transmission rate of the second service is adjusted according to different granularity, and the adjusted data transmission rates are different according to the different data transmission scheduling amounts of the first service and the second service so as to meet the data transmission scheduling demands of different degrees.

Step S24, scheduling data receiving resources of the network communication equipment aiming at the first service and the second service respectively based on the adjusted data transmission rate through a system kernel;

Step S25, the control network communication equipment receives response data aiming at the first service by using a first data receiving resource scheduled to the first service, and receives response data aiming at the second service by using a second data receiving resource scheduled to the second service;

By combining the related description of the method for realizing the scheduling of the communication resources of the network communication equipment, the corresponding adjustment of the first data receiving resources scheduled to the second service in the data receiving resources of the network communication equipment can be realized by adjusting the data transmission rate of the second service, so that the adjustment of the data receiving resources which are not scheduled to the second service, namely the adjustment of the second data receiving resources scheduled to the first service sharing the network communication equipment with the second service, is realized, and the size of the data receiving resources allocated to each service directly influences the response speed of the corresponding service. The application does not limit the method for realizing the scheduling of the data receiving resources of the first service and the second service by how the system kernel adjusts the data transmission rate of the second service and responding to the data transmission rate of the second service.

Referring to the system architecture schematic shown in fig. 3, the present application may set a data transmission scheduling rule of a speed limit (such as a data reception limiting rate) by invoking iptables (an operation tool of a network packet processing framework user space in a system kernel) through an expansion interface netd (a daemon for managing a network in Android) to a netfilter (a network packet processing framework in a kernel for processing data packets at different levels of a protocol stack, such as filtering, modifying, discarding, etc.), and a hashlimit module (which is an expansion module of iptables, may limit a data transmission rate of a service according to a specific rule, may control a matching rate of data by using a token bucket algorithm, and the present application does not detail a data transmission rate adjustment principle implemented by the present application) according to the data transmission rate adjustment rule, and adjusts a data transmission rate for a second service based on delay information of the first service.

And similarly, the second data receiving resource of the second service can be increased under the condition of increasing the data transmission rate of the second service, so that the first data receiving resource of the first service is reduced, and the relation between the first data receiving resource and the second data receiving resource after scheduling at the moment can be determined according to the scheduling degree.

And step S26, responding to the data transmission requests of the first service and the second service, and controlling the network communication equipment to sequentially transmit the request transmission data from the service belonging to the corresponding scheduling priority by the system kernel based on the scheduling priority of the first service and the second service.

Regarding the implementation method of step S26, reference may be made to the description of the corresponding portions of the context embodiment, which is not described in detail herein.

In summary, in the embodiment of the present application, in the case that the electronic device operates multiple services such as the first service and the second service, in order to ensure a high response speed of the first service, improve user experience, the system kernel dynamically adjusts the data transmission rate of the second service based on the delay information of the current first service, so as to implement scheduling of the data receiving resources of the shared network communication device, so that the first service can quickly receive the response data from the corresponding external device by using the scheduled first data receiving resources, and meanwhile, the second service can also slowly receive the response data from the corresponding external device by using the scheduled second data receiving resources, so that the second service does not stop operating due to data transmission scheduling, and by reasonably and dynamically scheduling the data receiving resources of each service with different scheduling priorities, the reliability of operation of each service is improved.

Referring to fig. 4, a flow chart of a data transmission scheduling method according to a third embodiment of the present application may describe a possible implementation manner of how to adjust the data transmission rate of the second service in the data transmission scheduling method described above. Based on this, as shown in fig. 4, the data transmission scheduling method proposed in this embodiment may include:

step S41, responding to a data transmission scheduling request of a first service and a second service operated by the electronic equipment, inquiring a time delay level to which time delay information of the first service belongs, and determining a target limiting rate configured for the time delay level;

Step S42, the data transmission rate of the second service in the system kernel of the electronic equipment is adjusted to be a target limiting rate;

Because the application needs to determine how to adjust the data transmission rate of the second service according to the current delay information of the first service, in the data transmission rate adjustment rule provided by the embodiment of the application, the delay of the first service can be graded according to the maximum value and the minimum value of the delay information allowed by the operation of the first service to obtain a plurality of delay levels, the corresponding delay information range is configured without the delay levels, the delay information under the delay levels is improved, and the reasonable limiting rate of the data transmission rate of the second service, namely the corresponding limiting rate is configured without the delay levels. The application does not limit the dividing result of each time delay level of the first service and the corresponding time delay information range and the numerical value of the limiting speed, and can be flexibly configured according to actual requirements or experience.

For example, if the delay information of the first service is denoted as rtt, the maximum value thresh_high of the data transmission rate of the second service is denoted as rate, which is generally a higher value, such as 100Mbps, etc., the present application does not limit the value thereof, the limiting rate or the adjusted data transmission rate may be denoted as limit_rate, and the configuration of the delay information ranges and limiting rates corresponding to different delay levels of the first service may be implemented according to the rules described below:

if(rtt > 1000ms)

limit_rate = rate / 16;

else if (rtt > 500ms)

limit_rate = rate / 8

else if (rtt > 200ms)

limit_rate = rate / 4

else if (rtt > 100ms)

limit_rate = rate / 2

it can be seen that, for the delay information of the first service, the delay information may be divided into 4 delay levels in the above example, the division may be implemented by four hierarchical delay information thresholds of 1000ms, 500ms, 200ms, and 100ms, and the delay information range corresponding to the corresponding delay level may be sequentially represented as rt > 1000ms, rt > 500ms (i.e. 1000ms is greater than or equal to rt > 500 ms), rt > 200ms (i.e. 500ms is greater than or equal to rt > 200 ms), and rt >100ms (i.e. 200ms is greater than or equal to rt >100 ms), but is not limited to the delay level division manner in the example and the delay information range corresponding thereto, and may be flexibly configured or adjusted according to practical situations. Based on this, when the first service has high delay, the first service can be quickly reduced to a suitable target limiting rate according to the adjustment logic.

For example, if the delay information of the current first service is 400ms, the target limiting rate of rate/4=100/4=25 Mbps may be determined as the data transmission rate after the second service is adjusted by querying the delay level corresponding to the range of 500ms being equal to or greater than rtt > 200ms, i.e., the else if (rtt > 200 ms).

In combination with the above analysis, in still other embodiments of the present application, if the delay information of the first service currently acquired is greater than the first delay threshold (for example, 100ms, etc., the present application does not limit the value thereof), the data transmission rate for the second service in the kernel of the electronic device system may be reduced based on the delay information of the first service. In one possible implementation, the reduced data transmission rate may be determined at this time in the manner of the query described in step S41 and step S42. In another possible implementation, the step size can be reduced according to the preset data transmission rate, and the data transmission rate of the second service can be gradually reduced in combination with the change of the delay information of the first service.

In the process of receiving corresponding response data through a network communication device shared by the first service and the second service, according to the received data scheduling rule described above, the system kernel determines that the network communication device transmits response data for the first service (may be sent in the form of a data packet or a message, etc., the data format of each response data is not limited according to the network communication protocol supported by the network communication device, and may receive and send the response data to the first service running in the application layer through a protocol stack according to a data receiving path shown by an arrow in fig. 3, so that the first service may perform a corresponding action based on the response data, and may generate new request sending data, and write the new request sending data into a data sending queue corresponding to the scheduling priority to which the first service belongs in the system kernel through a data sending path shown by an arrow in fig. 3.

In the data receiving process, if the network communication device is determined to transmit the response data for the second service, the redundant response data can be lost according to the currently configured data transmission rate because the data transmission rate is lower, so that occupation of data receiving resources of the network communication device is reduced, and the second service is prevented from stopping running.

Therefore, in order to ensure that the second service can still continue to operate under a lower flow, the reduced data transmission rate is limited to be greater than or equal to the minimum data transmission rate of response data of the second service, which can be expressed as thresh_low, and the value of the minimum data transmission rate can be determined according to the consumption condition of the second service on the data receiving resource, so that the value of thresh_low can be different for different second services, and the application does not limit the value of thresh_low.

According to the analysis, in the process of adjusting the data transmission rate of the second service, if the adjusted data transmission rate is determined to be less than or equal to the minimum data transmission rate, the data transmission rate of the second service can be adjusted to the minimum data transmission rate. The implementation can be achieved by the following adjustment logic:

if(rate <= THRESH_LOW)

limit_rate = THRESH_LOW

Similarly, when the currently acquired delay information of the first service is smaller than the second delay threshold, the data transmission rate of the second service in the kernel of the electronic device system can be increased based on the delay information of the first service, and the second delay threshold is smaller than the first delay threshold, so that the following adjustment logic implementation can be executed:

if (rtt < 30ms)

limit_rate = rate×2

It can be seen that the second delay threshold may be 30ms, but is not limited to this value. When the time delay of the first service is lower, the limitation on the second service can be properly relaxed, so that more data receiving resources are scheduled for the second service, more response data aiming at the second service are received, and more data can be sent by the background.

Step S43, the same network communication equipment is controlled to receive the response data aiming at the first service and the second service based on the adjusted data transmission rate through the system kernel;

regarding the implementation method of step S43, reference may be made to the description of the corresponding parts of the above embodiments, which are not described in detail in this embodiment.

Step S44, responding to the respective data transmission request of the first service and the second service, and writing the request transmission data of the corresponding service into a data transmission queue of the scheduling priority to which the service belongs through a system kernel;

step S45, the network communication equipment is controlled to sequentially send each request sending data in the corresponding data sending queue according to the scheduling priority of the different data sending queues through the system kernel.

In one possible implementation method of the data transmission scheduling rule provided by the present application, a plurality of data transmission queues with different scheduling priorities may be configured in pfifo _fast of the flow control module TC (Traffic Control) of the system kernel, such as three data transmission queues represented by b0, b1 and b2 shown in fig. 3, where the scheduling priority of the data transmission queue b0 is the highest, and the scheduling priority of the data transmission queue b2 is the lowest. The transmit data scheduling rule indicates that the system kernel will not transmit the request transmit data in the data transmit queue of the lower scheduling priority until the request transmit data in the data transmit queue of the higher scheduling priority is not transmitted.

Based on this, the system kernel may preferentially transmit each request transmission data in the data transmission queue b0, and after determining that all the request transmission data therein has been transmitted, transmit each request transmission data written in the data transmission queue b1 of the next scheduling priority, and after transmitting, if there is no request transmission data in the data transmission queue b0, retransmit each request transmission data written in the data transmission queue b2 of the next scheduling priority. It can be seen that, the different scheduling priorities of the present application correspond to different data transmission queues, and the data transmission queues configured by the system kernel are not limited to the three data transmission queues shown in fig. 3.

In practical application of the present application, as shown in fig. 3, for the above sending data scheduling rule, the sending data scheduling rule may be located in the egress rule chain (OUTPUT shown in fig. 3) of the NETFILTER MANGLE table, that is, the mangle table Mangle table of netfilter, and for the receiving data scheduling rule, the sending data scheduling rule may be located in the ingress rule chain (INPUT shown in fig. 3) of the NETFILTER FILTER table, that is, the filter table of netfilter, so that the system kernel correspondingly implements scheduling of the data sending and receiving process according to the corresponding scheduling rule. The data transmission process of each service with the application layer is realized by the system kernel through the socket interface and the Http protocol stack (OkHttp Stack), which can be determined according to the communication protocol under the corresponding operating system, including but not limited to the data transmission path and the data receiving path shown by the bold arrow line in fig. 3. It should be noted that, fig. 3 only illustrates an example of a data transmission scheduling method implemented based on a WIFI network card, and the implementation process of the data transmission scheduling method for multiple services is similar in a scene of implementing communication between an electronic device and an external device based on other types of network cards, which is not described in detail in one example.

In summary, in the embodiment of the present application, when the delay information of the first service is obtained, by determining the delay level to which the delay information belongs, the data transmission rate of the second service is quickly and accurately adjusted to the target limiting rate corresponding to the delay level, so that quick adjustment of queuing delay of response data of the first service is realized. In the data transmission process, the embodiment uses the data transmission queues with different scheduling priorities to realize queuing of the request transmission data of the services with different scheduling priorities, so that the data transmission sequence of each data transmission queue can be determined according to the scheduling priorities of each data transmission queue, each request transmission data stored in the data transmission queue with the highest scheduling priority is preferentially transmitted, the transmission of the request transmission data of the first service with the scheduling priority is timely transmitted, the transmission of the request transmission data of the second service with the lower scheduling priority is suspended, the queuing delay of the request transmission data of the first service is reduced, the delay information of the first service is rapidly and reliably reduced, and the experience of a user on the first service is improved.

Referring to fig. 5, a flow chart of a data transmission scheduling method according to a fourth embodiment of the present application may be described in one possible implementation manner of the response procedure of the data transmission request of each of the first service and the second service in the data transmission scheduling method described above, and for other steps of the data transmission scheduling method, reference may be made to descriptions of corresponding portions of the context embodiment, which will not be described in detail herein. Based on this, as shown in fig. 5, the response procedure proposed by the present embodiment may include:

Step S51, responding to the data transmission request of the first service and the second service, and determining a data transmission queue mapped to the current field value by reading the current field value of the service type field in the request transmission data by the system kernel;

In the embodiment of the application, the service type field can be configured in the request transmission data of each service, and the service type field is mapped to the data transmission queue corresponding to the scheduling priority through the field value, so that the queuing of the request transmission data of each service is realized. The service type field may be an 8-bit field such as TOS (Type of Service) bits of a packet IP header, which is used to request the quality of service and the service type of the transmission data, and the TOS value is adjusted to process the transmission data corresponding to the request. Optionally, the service type field of the present application may also be a DSCP (DIFFERENTIATED SERVICES Code Point) field, so as to configure the service type and the scheduling priority of the corresponding service, and the present application does not limit the differentiated service implementation principles of the two fields.

In the present application, a TOS service type field is taken as an example for illustration, and in the scenario of three data receiving queues b0, b1 and b2 corresponding to different scheduling priorities shown in fig. 3, each TOS value mapped to different data receiving queues and its corresponding service type can be as follows in table 1:

TABLE 1

Where md represents minimum delay, minimizing delay/time delay, mt represents maximizing throughput, mt represents maximizing reliability, and mmc represents minimizing monetary cost. After completing the mapping of the TOS values to the data transmission queues with different dispatching priorities according to the above table 1, in the response process of the data transmission request of each service, the system kernel may read the TOS value in the request transmission data from each service, and write the request transmission data into the data transmission queue mapped by the TOS value. Then, according to the scheduling priority of each data transmission queue, sequential transmission of the request transmission data stored in the plurality of data transmission queues can be realized. In practical application, for a service whose scheduling priority is not required, the field value of the service type field may be configured as the TOS value mapped by the b1 data transmission queue by default. Of course, when the scheduling priority of the service needs to be increased or decreased, the field value of the service may be modified to be the field value mapped by the data transmission queue corresponding to the scheduling priority after adjustment according to the field value configuration method described in the present application, and in this implementation process, an appropriate field value may be selected in combination with the service type to which the service belongs, and the mapping relationship shown in table 1 and the service types included in the mapping relationship may be used according to, but not limited to.

As shown in fig. 3, in the system configuration, settings may be set in the system to implement on-off control of the data transmission scheduling function provided in the embodiment of the present application, and in response to the start operation of the data transmission scheduling function, the data transmission scheduling method provided in the present application may be executed. The data queuing and the data transmission rate adjustment strategy proposed by the embodiment of the application can be realized through an extended system service Extended SystemService.

Step S52, determining whether the mapped data transmission queue is consistent with the scheduling priority of the service for transmitting the corresponding request transmission data, if not, proceeding to step S53, if so, proceeding to step S55;

Step S53, according to each field value of the service type corresponding to the dispatching priority of the service, the current field value of the service type field of the service in the system kernel is adjusted;

In the embodiment of the application, in the process of realizing the scheduling of the transmitted data based on the data transmission queue mapped by the TOS value, in order to improve the scheduling reliability, whether the data transmission queue mapped by the current field value in the request transmission data is consistent with the scheduling priority of the service for transmitting the corresponding request transmission data or not can be checked a priori, and if not, the field value of the service type field of the service can be modified according to the mapping relation shown in the table 1, so that the adjusted field value is mapped to the data transmission queue corresponding to the scheduling priority of the service.

Therefore, in the case that the scheduling priority of a foreground application needs to be improved, an API from frame to netd may be added to modify the TOS value corresponding to the service, so that the TOS field of the packet IP header (i.e. request for sending data) of the corresponding service application can be modified, and then an appropriate TOS value is set to map to the pfifo _fast queue b0 data sending queue, i.e. the data sending queue corresponding to the highest scheduling priority, but the mapping adjustment method is not limited to this mapping adjustment method. Therefore, the application adds the sending data scheduling rule in the kernel netfilter through the iptables, can take effect on different applications (namely, each service), and the system can uniformly manage and control the automatic and reasonable scheduling of the sending data request of each service, thereby meeting the priority sending requirement of the sending data request of the first service.

It can be seen that, in response to a request for adjusting a scheduling priority for any service, the present application may adjust an original field value of a service type field for the service in a system kernel by using each field value of a service type field corresponding to the scheduling priority after adjustment of the service request, so as to map the adjusted field value to a data processing queue corresponding to the scheduling priority after adjustment, where an implementation method includes, but is not limited to, the implementation method described above.

Step S54, writing the request sending data of the service into the data sending queue mapped to the adjusted field value;

Step S55, the request sending data of the service is written into a data sending queue mapped to the current field value of the service;

step S56, the network communication equipment is controlled to sequentially send each request sending data in the corresponding data sending queue according to the scheduling priority of the different data sending queues through the system kernel.

According to the analysis, the service type field of the business with different scheduling priorities is configured with the proper field value, namely the field value mapped by the data transmission queue corresponding to the scheduling priority to which the business belongs, so that the request transmission data of each business can be reliably written into the data transmission queue corresponding to the scheduling priority, and each request transmission data in the data transmission queue corresponding to the scheduling priority is sequentially transmitted from the higher scheduling priority to the lower scheduling priority through queuing the data transmission queue of each scheduling priority. Therefore, when the response speed is improved under the condition that the request for sending data of one or more services is required to be sent preferentially, when the dispatching priority is improved, the field value of the service type field can be adjusted, the adjusted field value can be ensured to be mapped to the data sending queue of the dispatching priority required to be adjusted, and the data priority sending requirement of the corresponding service is met.
