Although the performance of the network card hardware is higher and higher, after the system software is added, the network performance of the whole software and hardware integrated system often cannot reach the upper limit of the performance of the network card.

In order to make the network forwarding performance of the whole system software reach the line speed of the network card without packet loss, the line speed, i.e. a standard of the switching forwarding capability of the network device, is the maximum data volume that can be handled between the interface processor or interface card of the switch and the data bus. Usually, a network card driver is first located to determine whether the line speed of the network card can be reached when the network card driver performs message transceiving processing under a system. Under the premise that the bottom layer driver is required to reach the linear speed when the linear speed of the network card is reached, the situation of an upper layer protocol stack is added, but the problem that the performance of the bottom layer driver or the upper layer protocol stack in the network card cannot be determined in the prior art causes that the network card cannot reach the linear speed, so that the forwarding performance of the current message data is poor.

In the implementation manner, when the target network card is initialized, the first interface function in the system kernel can be called, the target interface function is registered on the basis of the first interface function, and the read function and the write function when the network interface is triggered to process the target message are implemented in the target interface function. The method comprises the steps of generating a corresponding trigger file in a system by calling a first interface function and a second interface function, generating an initial information group with a plurality of items of initial information and initial information as initial values in the trigger file to record a plurality of network interfaces for receiving or sending a target message, and recording the processed network interfaces when the network interfaces in the network card are triggered to process the target message, so as to record the processing mode of the target message in a network card driving layer.

and writing the second interface data into second initial information in the initial information group according to the write function to obtain second interface information for recording the second network interface.

In the implementation manner, when the network interface in the network card is triggered to process the target message, the corresponding trigger command can be received, and the network receiving data of the pair of network interfaces input during triggering is received based on the trigger command. Triggering a target interface function through a trigger command to enable a read function in the target interface function to be called, writing the received two interface data into two initial information in an initial information group respectively, assigning values to the two initial information according to two network interfaces respectively to obtain first interface information and second interface information which record the two network interfaces respectively, and forming target information when a target message is processed by the two interface information. When the network interface is triggered to process the target message at the drive layer of the network card, the used network interface is recorded in real time in the initial information group to obtain corresponding target information, and the processing mode of the target message in the drive layer of the network card is recorded by the target information.

Optionally, the method further comprises:

and if the trigger command is not received, taking the first initial information and the second initial information as the target information.

In the implementation manner, when the trigger command is not received, the target packet is processed through a protocol stack in a protocol layer in an upper layer network in the system, the target packet is not processed by using a network interface, and two pieces of initial information in the initial information group are directly used as target information when the target packet is processed, so as to express a corresponding network interface state when the target packet is processed by the protocol layer.

Optionally, the determining the sending mode of the target packet based on the target information includes:

determining variable information when the target message is received based on the target information;

and determining a sending mode of the target message according to the variable information.

In the above implementation manner, variable information that can represent a structure of a network interface in a system kernel when the target packet is received can be determined on the basis of the acquired target information when the target packet is processed, so that whether the target packet is sent by a driver layer of a network card or a protocol layer in an upper layer network is determined according to the variable information, and thus, two sending manners of the driver layer and the protocol layer are processed respectively.

Optionally, the determining, based on the target information, variable information when the target packet is received includes:

when the target message is received, setting an initial variable corresponding to a target structure of the target network card, wherein the initial variable comprises a first variable and a second variable, and the first variable and the second variable are default values;

updating the initial variable based on the target information, and determining the variable information when the target message is received.

In the implementation manner, in the process of receiving the target message, two static variables representing the change of the network interface structure by the kernel in the system can be set as initial variables, two variables in the initial variables are both default null values, and after corresponding target information is obtained when the target message is processed, the two variables in the initial variables are updated according to the target information, so that the change in the structure of the network interface is updated, variable information representing the current state of the network interface structure when the system receives the target message can be determined, and the effectiveness and the real-time performance of the variable information are improved.

In the above implementation, the initial variable is subjected to different update processes according to the specific situation of the target information. When the target information is the first initial information and the second initial information, it means that the target message is processed by using a protocol layer of an upper network, and the target message is processed without using a network interface in a driving layer, and two static variable first variables and second variables of the initial variables which are default values are directly used as variable information. When the target information is the first interface information and the second interface information, the target message is processed by using a network interface in a driving layer of the network card, a target function is called, the first interface information and the second interface information are respectively used as parameters to be calculated to obtain two return values, the numerical values of two static variables which are default values in the initial variables are respectively updated according to the calculated return values, and a third variable and a fourth variable are obtained to be used as variable information.

and when the receiving interface information is matched with the fourth variable, calling a sending function of the third variable in the driving layer to send the target message.

In the implementation manner, since the acquired variable information can represent the state of the network interface structure in the kernel, the sending manner when the target packet is sent can be determined according to the variable information. And judging whether the variable information is a first variable and a second variable or a third variable and a fourth variable, and judging the numerical value in the variable information. When the variable information is a first variable and a second variable, if the value of the variable is a default null value, the target message is processed by using a protocol layer in an upper network, so that a receiving function when the target message is received is directly called to upload the target message to a protocol stack in the upper network for processing, the protocol stack sends the target message, and the sending return value is the actual number of the target message. When the variable information is a third variable and a fourth variable, the numerical value of the variable is not controlled in a default mode, a network interface in a driving layer of the network card is used for processing the target message, information of a receiving interface in the process of receiving the target message is acquired and matched with the third variable and the fourth variable, when matching is successful, a sending function of the other variable is called respectively to send the target message, a sending return value is a null value, and a protocol layer in an upper layer network can be informed of not needing to process the target message. The corresponding transmission mode can be determined according to the variable information, so that two transmission modes in the driving layer and the protocol layer can be processed respectively.

Optionally, the testing the forwarding performance of the target packet based on the sending manner to obtain a test result includes:

testing the forwarding performance of the target message when the target message is sent in the sending mode based on a testing instrument;

when the forwarding performance is tested to be failed, the test result is that the performance problem of the forwarding performance is in the driving layer of the target network card;

and when the forwarding performance is tested to be passed, the performance problem of which the test result is the forwarding performance is in the protocol stack.

In the above implementation manner, after the target packet is forwarded in the sending manner, the forwarding performance of the target packet in the sending manner may be tested according to the test instrument, and when the test forwarding performance fails, the performance problem of the forwarding performance as a test result is located in the driving layer of the target network card, so that the forwarding performance cannot reach the linear speed. When the test forwarding performance passes, the performance problem of the forwarding performance is the test result in the protocol layer of the upper network, and the forwarding performance can reach the linear speed only if the protocol layer also has a promotion space. The method and the device can facilitate the user to adaptively adjust the driving layer of the network card and the protocol layer of the upper network in the system according to the test result, so that the forwarding performance of the system can reach the linear speed, and the forwarding performance of the system when forwarding the message data is improved.

Referring to fig. 2, fig. 2 is a schematic flow chart of a performance testing method according to an embodiment of the present application, where the method includes the following steps:

and step S200, generating an initial information group based on a target interface function in the target network card.

The corresponding initial information group is generated and added according to the target interface function called in the target network card, and a plurality of network interfaces during message processing can be recorded without modifying the drive and hardware of the system. The initial information group may include a plurality of pieces of initial information, which are respectively used to record a plurality of different network interfaces for receiving and sending the target packet. Optionally, the initial information group may be recorded in a form of a string array, and may record various data such as interface names, serial numbers, interface states, and the like of a plurality of related network interfaces when processing the target packet.

Step S300, based on the initial information group, determining the target information when the target message is processed.

The corresponding target information when the target message is processed in different modes can be determined on the basis of the initial information group. The different processing modes may include processing the target packet in a network interface mode in a driver layer in the target network card, or processing the target packet in a protocol stack mode in a protocol layer of an upper layer network of the system.

Step S400, determining the sending mode of the target message based on the target information.

And determining a sending mode when the target message is sent according to the target information for processing the target message. The sending mode may include sending through a driver layer in the target network card to drive a network interface, or sending through a protocol layer of an upper layer network of the system, where the system may be a Linux system or other operating systems.

Step S500, the forwarding performance of the target message is tested based on the sending mode, and a test result is obtained.

The forwarding performance of the target message after being sent in a determined sending mode is tested, when the forwarding performance of the target message in the system cannot reach the linear speed, the performance problem can be quickly and accurately positioned, and the test result of whether the performance problem is the reason of a driving layer of a network card or the reason of untimely processing of the target message by an upper layer network is obtained through the test.

Optionally, after the corresponding test result is obtained, the driver layer of the target network card or the protocol layer of the upper network in the system may be adjusted or modified according to the performance problem located in the test result, so as to adjust and solve the performance problem, so that when the system forwards the message data, the forwarding performance can reach the linear speed, thereby effectively improving the forwarding performance of the system.

In the embodiment shown in fig. 2, when the forwarding performance of the system for forwarding the message data does not reach the linear speed, the performance problem can be accurately and quickly tested and located.

Optionally, referring to fig. 3, fig. 3 is a detailed flowchart of step S200 according to an embodiment of the present application, and step S200 may further include steps S210 to S240.

Step S210, when initializing the target network card, calling a first interface function of the target network card.

When the target network card is initialized, the initialization function probe function in the calling target network card can be initialized. During initialization, a corresponding interface function of a PROC file system (a mechanism for accessing an internal data structure of a kernel and changing kernel settings during operation, and providing an interface for an operation of accessing kernel data of the system in a file system mode) may be set in a probe function to obtain a relationship between interfaces passing information in a kernel mode and an application mode. A first interface function in the PROC file system is called, which may be an interface function of the kernel interface of PROC _ create.

Step S220, registering the target interface function in the target network card based on the first interface function.

And the target interface function comprises a read function and a write function so as to realize the functions of reading and writing data, and is respectively used for inputting and acquiring the related information of the current network interface to be forwarded from an application state.

Step S230, generating a trigger file based on the first interface function and the target interface function.

After the first interface function and the target interface function are called, the information of the network interface transmitted from the application state can be received according to the first interface function and the target interface function, and a trigger file which can be triggered by a specific trigger state is generated in a related directory of a corresponding PROC file system in the system. Alternatively, the directory of the PROC file system may be/PROC/net, and the trigger file may be named a netbypass file.

Step S240, generating the initial information group in the trigger file.

The method comprises the steps of generating an initial information group capable of recording a plurality of network interfaces for receiving and sending a target message in a trigger file. Each item of initial information in the initial information group is used for recording one network interface in a plurality of network interfaces for receiving or sending the target message, and each item of initial information in the initial information group is an initial value.

Optionally, the initial information group may include two initial information, which are respectively denoted as recv _ dev [0] and recv _ dev [1], and the initial value of the initial information is a character string array with null value, and no relevant network interface is recorded.

In the embodiment shown in fig. 3, the processing procedure of the message can be recorded by setting and recording the initial information of the network interface without changing the overall logic and driving structure for receiving and sending the message in the whole system.

Optionally, referring to fig. 4, fig. 4 is a detailed flowchart of step S300 according to an embodiment of the present disclosure, and step S300 may further include steps S310 to S340.

In step S310, if a trigger command is received, the input network interface data is received.

When the driver layer of the target network card is used to call a network interface to process the target message, the system can generate and respond to a trigger command for triggering the state, where the trigger command may be an echo command, and can generate a corresponding trigger command according to a response Protocol based on a TCP (Transmission Control Protocol) or a UDP (User data packet Protocol). When a trigger command is received, a read function in a target interface function is triggered by responding to the trigger command, and input network interface data of a pair of network interfaces are received, wherein the network interface data comprise a pair of network interface data of first interface data of a first network interface and second interface data of a second network interface.

Optionally, the first interface data and the second interface data may also be two character string arrays, which respectively include the interface names, numbers, states, and other related data of the first network interface and the second network interface, and the first interface data and the second interface data may be respectively denoted as eth0 and eth 1.

Step S320, writing the first interface data into the first initial information in the initial information group according to the write function, to obtain the first interface information recorded on the first network interface.

The triggering command can trigger a writing function in the target interface function, the received first interface data is written into first initial information which is an initial value in an initial information group by calling the writing function, and the first initial information is assigned through the first interface data, so that first interface information capable of recording a first network interface is obtained.

Step S330, writing the second interface data into the second initial information in the initial information group according to the write function, to obtain the second interface information recorded on the second network interface.

The received second interface data can be written into second initial information which is an initial value in the initial information group by calling the write function, and the second initial information is assigned through the second interface data, so that second interface information capable of recording a second network interface is obtained.

It should be noted that, when receiving and responding to the trigger command, the two interface information, namely the first interface information and the second interface information, can form target information when processing a target message, and when triggering a network interface to process the target message at a driver layer of the network card, the network interface used in the initial information group is recorded in real time to obtain corresponding target information, and the target information is recorded in a processing manner of the target message in the driver layer of the network card.

Or, in step S340, if the trigger command is not received, the first initial information and the second initial information are used as the target information.

When the trigger command is not received, the target message is processed through a protocol stack in a protocol layer in an upper network in the system, the target message is not processed by using a network interface, two pieces of initial information in the initial information group are directly used as target information when the target message is processed, the target message is processed by the protocol layer, and a corresponding state which is not processed by using the network interface is expressed.

In the embodiment shown in fig. 4, different target information can be determined according to different processing modes to indicate the state during processing.

Optionally, referring to fig. 5, fig. 5 is a detailed flowchart of step S400 provided in the present embodiment, and step S400 may further include steps S410 to S420.

Step S410, determining variable information when receiving the target packet based on the target information.

On the basis of the acquired target information when the target message is processed, a specific numerical value of variable information which can represent a structure body of a network interface in a system kernel when the target message is received can be determined, so that the state of the structure body of the network interface in the system kernel can be acquired according to the variable information.

Step S420, determining a sending mode of the target packet according to the variable information.

The variable information can represent the interface state of a structure body of a network interface in a system kernel when the target message is processed, so that whether the target message is sent by a driving layer of a network card or a protocol layer in an upper layer network can be determined on the basis of the variable information, and the two sending modes of the driving layer and the protocol layer can be processed respectively.

In the embodiment shown in fig. 5, a static variable can be defined to represent the state of the structure of the network interface, so as to determine the sending mode when sending the target packet on the basis.

Optionally, referring to fig. 6, fig. 6 is a detailed flowchart of step S410 provided in the present embodiment, and step S410 may further include steps S411 to S412.

Step S411, when receiving the target packet, setting an initial variable corresponding to a target structure of the target network card.

The method includes defining corresponding initial variables based on a target structure, wherein the target structure can be a struct net _ device structure and can represent a structure of a network interface in a system kernel, the initial variables are static variables and can include a first variable and a second variable, the first variable and the second variable are default values, the default values are null values, and the first variable and the second variable can be recorded as dev1 and dev 2.

Step S412, updating the initial variable based on the target information, and determining the variable information when receiving the target packet.

After the target message corresponding to the target message is acquired, since the initial variable is a default null value, when the target message is received, the values of the two variables in the initial variable need to be updated according to the target message, so that the change in the structure of the network interface in the initial variable is updated, and the variable information when the target message is received is obtained.

Optionally, because the target information includes different information, the initial variable may be updated in different manners according to the different target information, and the updating manner may include: and when the target information is the first initial information and the second initial information, taking the first variable and the second variable in the initial variables as variable information.

When the target information is the first initial information and the second initial information, the target information is null, which indicates that the system processes the target message by using a protocol layer of an upper network and does not process the target message by using a network interface in a driving layer, so that when the target message is received, the state of a structural body of the network interface is not changed, and a first variable and a second variable of static variables of which two are default values in the initial variables can be directly used as variable information.

Optionally, the updating method may further include: when the target information is first interface information and second interface information, calling a target function to calculate based on the first interface information and the second interface information to obtain a first return value and a second return value; updating the numerical value of the first variable from a default value to a first return value to obtain a third variable; and updating the numerical value of the second variable from the default value to a second return value to obtain a fourth variable, and taking the third variable and the fourth variable as variable information.

When the target information is the first interface information and the second interface information, the target information is not a null value, the target message is processed by using a network interface in a driving layer of the network card, a target function is called, the first interface information and the second interface information are respectively used as parameters for calculation to obtain two return values, values of two static variables which are default values in the initial variables are respectively updated according to the return values obtained by calculation, and the first variable and the second variable of the default values are respectively assigned according to the first return value and the second return value to obtain a third variable and a fourth variable which are variable information. For example, the target function called when performing the calculation may be a dev _ get _ by _ name or other value-reducing function.

It should be noted that, for different target information, corresponding variable information capable of representing the state of the network interface structure in the kernel can be obtained according to different processing modes of the target packet.

In the embodiment shown in fig. 6, the variable information indicating the current state of the network interface structure when the system receives the target packet can be determined, so that the validity and the real-time performance of the variable information are improved.

Optionally, referring to fig. 7, fig. 7 is a detailed flowchart illustrating a step S420 according to an embodiment of the present application, and the step S420 may further include steps S421 to S425.

It should be noted that, the target packet is normally received and processed based on the variable information, and when the target packet needs to be sent, the values of the two variables in the variable information are determined, so as to obtain the state of the structure of the network interface, and determine the corresponding sending mode.

Step S421, when the variable information includes the first variable and the second variable, the receiving function when receiving the target packet is called to send the target packet to a protocol stack of an upper network.

When the variable information is a first variable and a second variable, the numerical value of the variable is a default null value, the state of the structural body of the network interface is not changed, and the processing mode is that a protocol layer in an upper network is used for processing the target message, so that a receiving function when the target message is received is directly called to upload the target message to a protocol stack in the upper network for processing.

Illustratively, the receiving function may be a netif _ receive _ skb or the like receiving function.

Step S422, the target message is sent based on the protocol stack.

After receiving the target message, the protocol stack of the upper layer network can send one or more target messages in the protocol layer by the protocol stack.

Optionally, after the target packet is sent in the protocol layer, the corresponding sending return value may be fed back, and the sending return value may be the actual number of the target packet.

Step S423, when the variable information includes the third variable and the fourth variable, acquiring receiving interface information for receiving the target packet.

When the variable information is the third variable and the fourth variable, the value of the variable is not controlled by default, the state of the structural body of the network interface changes, and the processing mode is to process the target message by using the network interface in the driving layer of the network card, so that the target message does not need to be sent by a protocol layer of an upper network, information of a receiving interface in the process of receiving the target message is acquired, and the acquired receiving interface information may include related information such as the interface name, the number, the state and the like of the network interface when the message is received.

Step S424, when the receiving interface information matches the third variable, a sending function of the fourth variable is called in a driving layer of the target network card to send the target message.

And when the information of the receiving interface is successfully matched with the third variable, for example, the name of the receiving interface is the same as the name of the corresponding first network interface in the third variable, the first network interface is the receiving interface when receiving the target message, the second network interface corresponding to the fourth variable is used as a sending interface, and a sending function of the second network interface corresponding to the fourth variable is called to send one or more target messages.

Step S425, when the receiving interface information matches the fourth variable, a sending function of the third variable is called in the driver layer to send the target packet.

And when the information of the receiving interface is successfully matched with the fourth variable, for example, the name of the receiving interface is the same as the name of a second network interface corresponding to the fourth variable, the second network interface is the receiving interface when receiving the target message, the first network interface corresponding to the third variable is used as a sending interface, and a sending function of the first network interface corresponding to the third variable is called to send one or more target messages.

Optionally, after the target packet is sent by using the network interface in the driver layer, a corresponding sending return value may be fed back, and the sending return value may be a null value, so as to notify a protocol layer of an upper layer network that the target packet does not need to be processed.

In the embodiment shown in fig. 7, the corresponding transmission method can be determined according to the variable information, so as to process the two transmission methods in the driver layer and the protocol layer respectively.

Optionally, referring to fig. 8, fig. 8 is a detailed flowchart of step S500 provided in the present embodiment, and step S500 may further include steps S510 to S530.

Step S510, testing the forwarding performance of the target packet when the target packet is sent in the sending manner based on a testing instrument.

After the target message is forwarded in the sending mode, the forwarding performance of the target message in the sending mode can be tested according to the testing instrument, and the testing instrument can be various testing instruments such as an IXIA network tester or a sbalance network tester.

Step S520, when the forwarding performance is tested to fail, the test result is that the performance problem of the forwarding performance is in the driving layer of the target network card.

When the test instrument detects that the forwarded target message cannot completely pass through, the forwarding performance is not passed, and the test result shows that the performance problem of the forwarding performance is located in the driving layer of the target network card, so that the forwarding performance cannot reach the linear speed.

Step S530, when the forwarding performance is tested to be passed, the performance problem of which the test result is the forwarding performance is in the protocol stack.

When the test instrument detects that the forwarded target message can completely pass through, the forwarding performance passes through, the test result is that the performance problem of the forwarding performance is in a protocol layer of an upper layer network, and the forwarding performance can reach the linear speed only if the protocol layer also has a promotion space.

In the embodiment shown in fig. 8, the position of the performance problem can be quickly and accurately located on the basis of the separately processed sending mode, so that the user can adaptively adjust the driving layer of the network card and the protocol layer of the upper network in the system according to the test result, the forwarding performance of the system can reach the linear speed, and the forwarding performance of the system when forwarding the message data is improved.
