Detailed ways

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to FIG. 1 , it shows a flowchart of a method for network quality detection in an embodiment of the present invention, the method is applied to a receiving end, and the method for network quality detection includes the following steps:

Step 101: When receiving multiple data packets from the sending end, determine the respective receiving time and sending time of the multiple data packets.

In the embodiment of the present invention, in general, when transmitting audio and video data in a normal network, in order to maximize the saving of network traffic, compression and encoding are performed according to a specific encoder, and then transmitted to the peer end through the network for decoding and playback. During the transmission process, it is generally necessary to send packets in packets. For example: commonly used video encoding formats H264, H265; audio encoding formats PCM, AAC, etc., the transmission format may be PS, PES, TS or custom packaging format, no matter which packaging format, generally each transmission packet contains a header, payload There are two parts to the data. The header contains additional information such as audio and video type, format, and timestamp, and the payload data contains audio and video encoding data.

At present, in the process of network transmission, the quality of the downlink network determines whether the video and audio that users watch are smooth, and whether the picture quality is high enough. The higher the network quality, the higher the video bit rate can be used, and the higher the image quality can be. In the downlink network, audio and video data are transmitted from the opposite end to the local end through the network. Among them, the opposite end in the network is the sending end for sending audio and video data packets, and the local end is the receiving end for receiving Audio and video data packets, and then forward the received audio and video data packets to the back-end equipment for processing, and then play and display them to users. The higher the network quality, the better the sound quality and picture quality users will enjoy, and the better the user experience will be.

When the sending end sends audio and video data packets, the sending end will add a time stamp in the header of each data packet, and the time stamp can be added according to the system time of the sending end itself. When the receiving end receives each audio and video data packet, there will also be a receiving time. The receiving time can be the time of the receiving end's own system. It is understandable that the system time of the receiving end may be different from the system time of the sending end. Not the same. When the receiving end receives multiple data packets from the sending end, it can determine the sending time of each data packet through the timestamp in the packet header, and determine each data packet according to the receiving end's own system time when each data packet is received. The time the packet was received.

As an example: a sender can start sending data packets according to its own system time 2020.3.3.8:00:000, and send a data packet every 30 milliseconds (ms), then the timestamp of the second data packet will be: 2020.3. 3.8:00:030; the timestamp of the third data packet will be: 2020.3.3.8:00:060, and so on; the time when the receiving end receives the first data packet may be: 2020.3.3.8:01:000 , the time of the second data packet is: 2020.3.3.8:01:030, the time of the second data packet is: 2020.3.3.8:01:060, and so on. The time of 1 second is the inherent delay of the downlink network, that is, when the quality of the downlink network is the best, it takes 1 second for the data packets sent from the sending end to reach the receiving end.

If the distance between the receiving end and the sending end is very far, and there are multiple time zones, then the time of the receiving end can be determined according to the local time. For example: the sending time of the sending end is 2020.3.3.8:00:000 Beijing time, and the receiving end is in Switzerland, then The time at the receiving end may be 2020.3.3.1:10:000 Swiss time, where 1:00 and 8:00 are the time zone difference between Beijing time and Swiss time, and 10 seconds is the inherent delay of the downlink network, that is, the data sent from the Beijing sending end It took 10 seconds for the packet to reach the receiving end in Switzerland.

Step 102: Determine the sending time difference between the sending times of the multiple data packets, and determine the receiving time difference between the receiving times of the multiple data packets.

In the embodiment of the present invention, after determining the receiving time and sending time of multiple data packets, the sending end determines the sending time difference between the sending times of the multiple data packets and the receiving time difference between the receiving times, that is, using the later The receive time of the received packet is subtracted from the receive time of the earlier received packet, and the send time of the later received packet is used minus the send time of the earlier received packet. The specific steps are:

Step s1: Divide every two data packets with a preset number of data packets in the plurality of data packets into one group to obtain multiple groups of data packets;

Step s2: determine the sending time difference between the later received data packet and the earlier received data packet in each group of data packets;

Step s3: Determine the receiving time difference between the later received data packet and the earlier received data packet in each group of data packets.

In the embodiment of the present invention, the receiving end first divides every two data packets with a preset data packet interval among multiple data packets into a group, so that multiple groups of data packets can be obtained, for example: every two data packets with an interval of 2 The data packets are divided into a group, then the first data packet and the fourth data packet are a group, the second data packet and the fifth data packet are a group, the third data packet and the sixth data packet By analogy, multiple data packets can be divided into multiple groups of data packets. Of course, if high-sensitivity detection of network quality is required, the optimal solution is to divide adjacent two data packets into A group, that is, the first data packet is a group with the second data packet, the third data packet is a group with the second data packet, and the fourth data packet is a group with the third data packet, and so on.

After dividing the groups, use the receiving time of the data packets received later in each group to subtract the receiving time of the data packets received earlier, and similarly, use the sending time of the data packets received later in each group The sending time of the data packets received earlier is subtracted to obtain the receiving time difference and sending time difference of each group.

Using the above example: according to the division of two adjacent data packets, the sending time and receiving time of the first data packet and the second data packet are respectively: 2020.3.3.8:00:000, 2020.3.3.8:00:030, 2020.3. 3.8:01:000, 2020.3.3.8:01:030; the sending time and receiving time of the third data packet and the second data packet are: 2020.3.3.8:00:090, 2020.3.3.8:00:060, 2020.3 .3.8:01:090, 2020.3.3.8:01:060, respectively calculate the receiving time difference and sending time difference of the two groups, the receiving time difference between the first data packet and the second data packet group is 30ms, and the sending time difference is 30ms; the third The receiving time difference between the first data packet and the second data packet group is also 30ms, and the sending time difference is also 30ms.

Step 103: According to the difference between the receiving time difference and the sending time difference, determine the quality of the network during the transmission of multiple data packets.

In the embodiment of the present invention, after the receiving time difference and the sending time difference of the data packets are determined, the quality of the network during transmission of multiple data packets can be determined according to the difference between the receiving time difference and the sending time difference. That is, the quality of the network during the transmission of multiple data packets can be determined by subtracting the difference between the receiving time difference calculated by the same group and the sending time difference calculated by the same group. The specific steps are:

Step t1: Obtain the delay time corresponding to the group of data packets according to the difference between the receiving time and the sending time of each group of data packets;

Step t2: Accumulate the respective delay times of multiple data packets to determine the accumulated delay time;

Step t3: According to the relationship between the accumulated delay time and the preset threshold, determine the quality of the network during the transmission of multiple data packets.

After obtaining the receiving time difference and sending time difference of each data packet, the sending end subtracts the sending time difference from the receiving time difference of the group to obtain a result value, which is the corresponding data packet of the group. delay time.

Using the above example: the receiving time difference between the first data packet and the second data packet group is 30ms, and the sending time difference is 30ms, then the delay time of this group of data packets is: 30ms-30ms=0, which means that the corresponding delay of this group of data packets The time is 0, that is, there is no delay when the network transmits these two data packets, and the network quality is the best; the receiving time difference between the third data packet and the second data packet group is also 30ms, and the sending time difference is also 30ms, then the The delay time of a group of data packets is: 30ms-30ms=0, which means that the delay time corresponding to this group of data packets is 0, that is, there is no delay when the network transmits these two data packets, and the network quality is the best.

After obtaining the corresponding delay time of each group, the delay time of each group is accumulated to obtain the accumulated delay time, and finally, according to the relationship between the accumulated delay time and the preset threshold value, the network is determined during the transmission of multiple data packets. quality.

Following the above example: the delay time of the first data packet and the second data packet group is 0; the delay time of the third data packet and the second data packet group is 0, and the result obtained by accumulating the two is also 0, according to this The relationship between the value and the preset threshold can determine the quality of the network during the transmission of multiple data packets. specific:

When the accumulated delay time is equal to the preset threshold, it is determined that the quality of the network during the transmission of multiple data packets is normal, so that the multiple data packets received by the receiving end are not delayed; when the accumulated delay time is greater than the preset threshold, It is determined that the network quality is abnormal during the transmission of multiple data packets on the network, causing delays in the multiple data packets received by the receiving end.

In the embodiment of the present invention, the preset threshold is a threshold that characterizes the network quality. Generally, the preset threshold is 0 to represent the best network quality, and the data packets received by the receiving end have no delay (except the inherent delay). Then, multiple The cumulative delay time of the data packet is equal to 0, indicating that the quality of the network is normal during the transmission of multiple data packets, and the multiple data packets received by the receiving end are not delayed; and if the cumulative delay time of multiple data packets is greater than 0, it indicates that the network is transmitting The quality of multiple data packets is abnormal, and multiple data packets received by the receiving end are delayed.

Following the above example: the delay time of the first data packet and the second data packet group is 0; the delay time of the third data packet and the second data packet group is 0, and the result of accumulating the two is also 0, which is equal to the predetermined If the threshold is set to 0, the quality of the network is normal during the transmission of the above three data packets, and there is no delay in the three data packets received by the receiving end; if the cumulative result of the two is not 0, but greater than 0, then the network is transmitting the above The quality of the three data packets is abnormal, and the three data packets received by the receiving end are delayed. It can be understood that if in the preceding steps, the receiving time of the same group of earlier data packets is used to subtract the receiving time of the later data packets, then the difference is negative, and the difference of sending time also needs to be used The sending time of the earlier data packet minus the sending time of the later data packet, if the network quality is abnormal and the delay occurs, then the accumulated delay time accumulated in the end will be a negative value, and the above-mentioned condition for determining the network quality needs to be changed to be equal to A preset threshold of 0 is normal, and a value less than the preset threshold of 0 is abnormal.

In the case where the accumulated delay time is greater than the preset threshold, if the accumulated delay time is greater than the preset threshold and the change value of the accumulated delay time over time is less than or equal to the preset change value, it is determined that the network is transmitting multiple data packets The network quality of is stable and there is a fixed delay. That is, if the delay time of the first data packet and the second data packet group is 0; the delay time of the third data packet and the second data packet group is 10ms, and the delay time of the fourth data packet and the third data packet group is 0, the delay time of the fifth data packet and the fourth data packet group is 0, and the result obtained by accumulating the four is 10ms, which indicates that the network quality during the transmission of these five data packets is stable, and there is a fixed The delay is 10ms. The most intuitive manifestation is that the audio and video that the user enjoys freezes, often needs to be buffered, and cannot be played smoothly.

In the case that the accumulated delay time is greater than the preset threshold, if the accumulated delay time is greater than the preset threshold and the change range of the accumulated delay time over time is greater than the preset change value, then determine the network quality during the transmission of multiple data packets of the network Deteriorated and does not meet preset bandwidth requirements. That is, if the delay time of the first data packet and the second data packet group is 0; the delay time of the third data packet and the second data packet group is 10ms, and the delay time of the fourth data packet and the third data packet group is 8ms, the delay time of the fifth data packet and the fourth data packet group is 0ms, and the result obtained by accumulating the four is 18ms, which indicates that the network quality during the transmission of these five data packets is degraded, and it does not comply with Preset bandwidth requirements. The most intuitive manifestation is that the audio and video that the user enjoys is stuck at a certain time, and cannot be played smoothly at all. It needs to be buffered for a long time, and the sound will appear before the screen, causing the user to have no sense of appreciation experience at all.

In the embodiment of the present invention, according to the quality of the network during the transmission of multiple data packets, an adjustment prompt can be sent to the sending end to prompt the sending end to adjust the total data volume of the data packets sent to the receiving end in a single time; and/or output reception adjustment Prompt, to prompt the user at the receiving end to adjust the total data volume of a single received data packet. That is, when there is a network delay or the network bandwidth cannot meet the demand at all, an adjustment prompt is sent to the sender. After receiving the prompt, the sender adjusts the total data volume of the data packets sent to the receiver alone to adapt to the network quality, or , output an adjustment prompt to the receiving end. After receiving the prompt, the receiving end adjusts the total data volume of the data packets received by the pair to adapt to the network quality, or sends an adjustment prompt to the sending end and the receiving end at the same time, so that both Adjust to adapt to the network quality, and finally ensure that users can enjoy the audio and video images that meet the current network quality. The most intuitive manifestation is that if the network quality is the best, the audio and video data packets that meet the 1080P quality can be transmitted, and users can enjoy 1080P When the network quality is not satisfactory, it will automatically adjust to the transmission method of 720P audio and video data packets. When the network quality is worse, it will be reduced again. Of course, after the network quality is restored, it can be restored to 1080P quality audio and video data packet transmission mode for transmission.

In order to describe the solution of the present invention more intuitively, as shown in FIG. 2 , it shows a schematic diagram of a method for realizing network quality detection based on the sending end and the receiving end of the downlink network in the embodiment of the present invention. The network includes the sending end and the receiving end. The sender sends data packets, and the receiver receives data packets.

Assuming that the sending end continues to send data packets to the receiving end at intervals of 30ms, the sending time from the first data packet (1 in Figure 2 indicates the first data packet) is: 0ms, 30ms, 60ms, 90ms...n*30ms ; The receiving time of the data packet received by the receiving end is: T0+0ms, T0+30ms, T0+60ms, T0+90ms...T0+n*30ms; where T0 is the inherent delay.

Under normal circumstances, when the network quality is normal, the receiving time of the data packet received by the receiving end is: T0+0ms, T0+30ms, T0+60ms, T0+90ms...T0+n*30ms, if the second data packet (Fig. 2 in 2 means that the second data packet arrives at the receiving end with a delay of 10ms, then the receiving time of the second data packet becomes: T0+40ms, taking adjacent data packets as a group, and calculating the receiving time difference and sending time difference of each group respectively , then have: the receiving time difference of the second data packet and the first data packet: T0+40ms-(T0+0ms)=40ms, sending time difference: 30ms-0ms=30ms; The receiving time difference of the 3rd data packet and the second data packet : T0+60ms-(T0+40ms)=20ms, sending time difference: 60ms-30ms=30ms.

The delay time between the second data packet and the first data packet is: 40ms-30ms=10ms, which means that the network transmits the two data packets abnormally, the receiving end delays receiving the second data packet, the third data packet and the second The delay time of the data packet is: 20ms-30ms=-10ms, which means that the network returns to normal during the transmission of the two data packets, and the receiving end receives the third data packet according to the normal time, and accumulates the delay time of the two to obtain The cumulative delay time is: 10ms+(-10ms)=0ms, that is, the receiving end receives the third data packet according to the normal time, although the network is delayed in the middle, it recovers at the time of the third data packet.

In the above process, if the third data packet is also delayed by 10ms, that is, the receiving time of the third data packet becomes T0+70ms, then the receiving time difference between the third data packet and the second data packet: T0+70ms-(T0 +40ms)=30ms, sending time difference: 60ms-30ms=30ms, the delay time of the 3rd data packet and the 2nd data packet is: 30ms-30ms=0ms, and final accumulative delay time is: 10ms+0ms=10ms, that is, receiving The end received the second and third data packets with delay, and the network was delayed, but the network delay stabilized, and the delay time was fixed at 10ms.

In the above process, if the third data packet is delayed by 20ms, that is, the receiving time of the third data packet becomes T0+80ms, then the receiving time difference between the third data packet and the second data packet: T0+80ms-(T0+ 40ms)=40ms, the sending time difference: 60ms-30ms=30ms, the delay time between the third data packet and the second data packet is: 40ms-30ms=10ms, and the final cumulative delay time is: 10ms+10ms=20ms, that is, the receiving end Delayed reception of the second and third data packets, the network delay occurs, and the network delay time becomes longer, the network quality deteriorates, and the actual bandwidth does not meet the required bandwidth.
