The target network may be a network for exchanging data between the first device and the second device, and the target network may include network devices for forwarding data exchanged between the first device and the second device, that is, the first device may send data to the second device through the target network; for example, the first device may send the first data to the target network, which forwards the first data to the second device, where the first data may be any data that the first device needs to send to the second device. Similarly, the second device may send data to the first device via the target network; for example, the second device may send second data to the target network, which is forwarded by the target network to the first device, where the second data may be any data that the second device needs to send to the first device. The network devices may include, but are not limited to: gateway devices, routers, switches, base stations, etc. The first data or the second data may refer to audio-visual data (e.g., video conference data, video live data), image data, game application data, and the like. The target network may refer to a wireless network or a wired network, which may include a mobile data network or a wireless fidelity (Wireless Fidelity, wiFi) network. In one embodiment, taking an example that the first device transmits the first data to the second device through the target network, a process of exchanging data between the first device and the second device is described, and as shown in fig. 2, the process of exchanging data includes the following steps s1 to s5.
s1, the first device encodes the first data to be transmitted to obtain encoded data.

The attribute information includes an identification of the first device, an identification of the second device, a data transmission time, and the like, and the identification may refer to an IP address, a telephone number, a serial number, or the like of the device.
And s3, the first equipment sends the data forwarding request to the target network.
In step s1-s3, in order to improve the data transmission security of the target network and save the data transmission resources, the first device may use a preset encoding algorithm to encode the first data to be sent, so as to obtain encoded data. The preset encoding algorithm may refer to an encoding algorithm agreed between the first device and the second device, and the preset encoding algorithm may include, but is not limited to: adaptive differential pulse code modulation (Adaptive Differential Pulse Code Modulation, ADPCM), pulse code modulation (Pulse Code Modulation, PCM), base64 (an encoding algorithm), and the like. Further, the first device may generate a data forwarding request and send the data forwarding request to the second device.
And s4, the target network sends the encoded data to the second device. Specifically, the target network may receive the data forwarding request, query a path for sending the encoded data to the second device according to the identifier of the second device included in the data forwarding request, and send the encoded data to the second device according to the path.
And s5, the second equipment decodes the encoded data to obtain first data.

The preset decoding algorithm may refer to a decoding algorithm agreed between the first device and the second device, and the preset decoding algorithm may be a decoding algorithm corresponding to the above-mentioned preset encoding algorithm.

(3) When the target network is in a congestion state, the data transmission speed of the target network can be acquired. (4) And adjusting the speed of the first device sending the data to the second device according to the data transmission speed.

Based on the above description of the data processing system, please refer to fig. 3, fig. 3 shows a data processing method according to an embodiment of the present invention, where the method is applied to the network device in fig. 1, and the method specifically includes the following steps S101 to S104.
S101, in the process that the first device sends data to the second device through the target network, the amount of data blocking of the target network is obtained, the data blocking amount includes an amount of data to be forwarded to the second device in a transport layer of the target network and an amount of data buffered by an application layer of the target network.
When the first device needs to send data to the second device, the first device detects an available network, connects to the available network, and determines the available network as a target network. The usable network herein may refer to a network that can be used for transmitting data, wherein when the number of usable networks is plural, a network with the best communication quality may be regarded as a target communication network. In the process that the first device sends data to the second device through the target network, in order to avoid that the target network is in a congestion state, the network device may acquire the data blocking amount of the target network. The data blocking amount includes the amount of data to be forwarded to the second device in the transport layer of the target network, and the amount of data buffered in the application layer of the target network, that is, the data blocking amount may be the sum of the amount of data blocking in the transport layer of the target network (that is, the amount of data to be forwarded to the second device in the transport layer of the target network) and the amount of data buffered in the application layer of the target network, that is, the amount of data blocking is the amount of data corresponding to the data waiting for the target network to forward to the second device in the data sent by the first device.
S102, determining the data transmission state of the target network according to the data blocking quantity.
The more the data blocking amount of the target network is, the more the data amount of the target network needs to be forwarded is indicated, namely the probability that the target network is in a congestion state is relatively high; the smaller the data blocking amount of the target network, the smaller the data amount which the target network needs to forward, i.e. the smaller the probability that the target network is in a congestion state. Thus, the network device may determine the data transmission status of the target network based on the data blocking amount, where the data transmission status includes congestion status, saturation status, non-saturation status.
And S103, if the target network is in a congestion state, acquiring the data transmission speed of the target network.
If the target network is in a congestion state, the target network indicates that there is an excessive data volume to be forwarded in the target network, and if the target network is in the congestion state for a long time, the communication service in the target network is easily interrupted. Thus, the network device may obtain the data transmission speed of the target network, where the data transmission speed of the target network may be determined according to the historical data transmission speed of the target network or according to the real-time data transmission speed of the target network.
S104, adjusting the speed of the first equipment for sending data to the second equipment according to the data transmission speed of the target network.
The network device may adjust the speed of the first device sending data to the second device according to the data transmission speed of the target network, i.e. may reduce the speed of the first device sending data to the second device according to the data transmission speed of the target network. Therefore, the data volume sent by the first equipment to the target network can be reduced, the data blocking volume of the target data network is further reduced, and the target network can be quickly restored to a normal state.
In the embodiment of the invention, the data transmission state of the target network can be determined according to the data blocking amount of the target network, namely whether the target network is in a congestion state can be verified through the data blocking amount of the target network, and whether the target network is in the congestion state does not need to be verified according to the receiving time of the data, so that the problem of the blocking of the target network can be rapidly discovered; when the target network is in a congestion state, the speed of sending data from the first device to the second device is adjusted through the data transmission speed of the target network, so that the target network can be prevented from being in the congestion state for a long time, the target network can be quickly restored to a normal state, the communication service in the target network is ensured to be restored to be normal, and the user experience is improved.
In one embodiment, step S102 may include the following steps S11-S12.
And s11, determining the data transmission delay of the target network in a preset time period according to the data blocking quantity.
And s12, if the data transmission delay of the target network in the preset time period is greater than a preset delay threshold, determining that the target network is in a congestion state.
In steps s11 to s12, in order to improve accuracy of determining the data transmission state of the target network, the network device may determine, according to the data blocking amount, a data transmission delay of the target network in a preset time period, where the data transmission delay is smaller, which indicates that the data transmission speed of the target network is faster, and that the target network has no problem of blocking; the data transmission delay is larger, which indicates that the data transmission speed of the target network is lower, and the target network has the problem of blocking. Therefore, if the data transmission delay of the target network in the preset time period is greater than the preset delay threshold, determining that the target network is in a congestion state.
In one embodiment, step s11 may include the following steps s 21-s 22.
s21, obtaining a first encoding speed of the first device in the preset time period and a data blocking amount of the target network in the preset time period.
s22, determining the data transmission delay of the target network according to the quotient of the data blocking amount and the first coding speed.
In steps s21 to s22, the network device may acquire a first encoding speed of the first device in the preset period of time, and a data blocking amount of the target network in the preset period of time, where the first encoding speed may be sent to the network device by the first device. Optionally, the network device may obtain an average value of the encoding speeds of the first device in a preset time period, determine the average value as the first encoding speed, determine an average data blocking amount of the target network in the preset time period, and determine the average data blocking amount as the data blocking amount of the target network in the preset time period. The preset time period may refer to the first device going to the second device any one of the time periods within which the device transmits data. Further, the network device may calculate a quotient of the data blocking amount and the first encoding speed, and determine the quotient of the data blocking amount and the first encoding speed as the data transmission delay of the target network.
Optionally, step S102 may include: the network device may acquire, using the preset time interval as a sampling unit, first encoding speeds of the first device at a plurality of moments in a preset time period, and acquire, using the preset time interval as a sampling unit, data blocking amounts of the target network at the plurality of moments in the preset time period. And determining the quotient of the data blocking quantity at each moment and the first coding speed as the data transmission delay of the target network at the moment, and determining that the target network is in a congestion state when the data transmission delays at a plurality of adjacent moments are all larger than a preset delay threshold.
In one embodiment, step S103 may include the following steps S31-S32.
s31, acquiring the data transmission speed of the target network in a plurality of historical time periods.
And s32, carrying out weighted summation on the data transmission speeds in the plurality of historical time periods to obtain the data transmission speed of the target network.
In steps s31 to s32, since the target network is affected by external interference or its own performance, the fluctuation of the data transmission speed of the target network is relatively large, if the speed of the first device for transmitting data is adjusted according to the current real-time speed of the target network, the congestion state of the target network is likely to occur frequently. Therefore, the network device can acquire the data transmission speed of the target network in a plurality of historical time periods, and the data transmission speeds in the plurality of historical time periods are weighted and summed to obtain the data transmission speed of the target network. The data transmission speed of the target network can be expressed by using formula (1).
Wherein AR n For the data transmission speed of the target network, AR k For the data transmission speed of the target network in the kth history period, n represents the number of history periods, x represents the weight coefficient, x e (0, 1), which may refer to a default value of the network device or set by the user.
In one embodiment, step S104 may include steps S41-S42 as follows.
s41, obtaining the decoding speed of the received data by the second device, and a rate of change of the data transmission speed of the target network.
s42, determining the minimum speed value from the data transmission speed and the decoding speed of the target network.
s43, adjusting the speed of the first device sending data to the second device according to the minimum speed value and the change rate.
In steps s41 to s42, the network device may acquire the decoding speed of the received data by the second device and the rate of change of the data transmission speed of the target network. The change rate can be calculated according to the data transmission speed of the target network in a plurality of historical time periods, and the change rate can be used for indicating the change speed of the data transmission speed of the target network data, namely, the larger the change rate is, the faster the change of the data transmission speed of the target network is, namely, the larger the fluctuation of the data transmission speed of the target network is; the smaller the rate of change, the slower the change in the data transmission speed of the target network, i.e., the smaller the fluctuation in the data transmission speed of the target network. The decoding speed of the second device can influence the data quality, namely if the decoding speed of the second device is higher, the data received by the second device can be decoded in time, and the probability of abnormality of the data is lower; if the decoding speed of the second device is slower, the data received by the second device cannot be decoded in time, and the data redundancy has abnormal problems such as jamming or messy codes, namely the probability of the data abnormality is higher. Therefore, the network device can determine a minimum speed value from the data transmission speed and the decoding speed of the target network, and adjust the speed of the first device sending data to the second device according to the minimum speed value and the change rate. Therefore, the target network can be quickly restored, and abnormal problems such as jamming and the like of the data in the second equipment can be avoided. Wherein the minimum speed value may be expressed by formula (2).
SR＝min(AR n ,CR n ) (2)
Wherein CR in equation (2) n The decoding speed of the second device is the decoding speed of the second device, and the decoding speed of the second device can be reported to the network device by the second device; SR is the minimum speed value.
In this embodiment, step s43 may include the following steps s51 to s52.
s51, calculating a second encoding speed according to the minimum speed value and the change rate.
s52, sending the second coding speed to the first device, so that the first device adjusts the coding speed of the first device according to the second coding speed to adjust the speed of the first device sending data to the second device.
In steps s51 to s52, since the data transmission speed of the target network stores the volatility, the network device may calculate the second encoding speed according to the minimum speed value and the change rate, and send the second encoding speed to the first device, so that the first device encodes the data to be transmitted at the second encoding speed, that is, the second device reduces the encoding speed of the data to be transmitted, so that the speed of the first device transmitting the data to the second device can be reduced. Wherein the second encoding speed can be expressed by formula (3).
RR＝SR·(1-μ) (3)
Wherein RR in the formula (3) is the second encoding speed, and μ represents the rate of change of the data transmission speed of the target network.
In one embodiment, after step S104, the method may further include: if the target network is restored to a normal state, the first coding speed is sent to the first device, so that the first device adjusts the coding speed of the first device according to the first coding speed, and the speed of the first device sending data to the second device is adjusted.
The first encoding speed is the encoding speed of the first device when the target network is in a normal state, the second encoding speed is the encoding speed of the first device when the target network is in a congestion state, and the first encoding speed is greater than the second encoding speed, wherein the normal state can refer to a saturated state or a non-saturated state. If the target network is restored to a normal state, the data blocking amount in the target network is less or zero, and the first device can be controlled to encode the data to be transmitted at a higher encoding speed, so that the data transmission efficiency is improved. That is, the network device may send the first encoding speed to the first device, so that the first device encodes the data to be sent according to the first encoding speed, so as to adjust the speed at which the first device sends the data to the second device.
The data processing method provided by the embodiment of the invention can be applied to scenes such as audio and video data (such as video conference data and video live broadcast data), image data and game application data. The following describes in detail a data processing method in the embodiment of the present invention, taking an example that a first device sends streaming media data to a second device. The streaming media data may refer to data transmitted in a target network in a streaming manner, and the streaming manner may specifically refer to that the first device collects the streaming media data and issues the collected streaming media data to the target network, the target network sends the collected streaming media data to the second device in real time, and the second device can know the data collected by the first device in real time by displaying the streaming media data. Streaming media data may specifically refer to video live data, such as event live data, teaching live data, game live data, and so forth. As shown in fig. 4, the data processing method may include the following steps s61-s63.
s61, the first device may send streaming media data to the second device through the target network. The first device adopts streaming media data, and sends the acquired streaming media data to the target network while acquiring the streaming media data, and the target network forwards the acquired streaming media data to the second device. The specific process of the first device sending the streaming media data to the second device may refer to steps s1 to s5.
And s62, in the process that the first device sends the streaming media data to the second device through the target network, the network device can acquire the data blocking amount in the target network. The data blocking amount is the data amount corresponding to the streaming media data waiting for the target network to forward to the second device in the streaming media data sent by the first device, that is, the data blocking amount is the data amount corresponding to the streaming media data buffered by the application layer of the target network and the data blocking amount of the transmission layer of the target network.
s63, the network device may determine the data transmission status of the target network according to the data blocking amount of the target network. If the data blocking amount of the target network is larger, the fact that a large amount of streaming media data exists in the target network is indicated that the streaming media data is not forwarded in time, and therefore when the data blocking amount of the target network is larger than a preset data amount threshold value, the target network is determined to be in a congestion state. Or determining the data transmission delay of the target network in the preset time period according to the data blocking amount of the target network in the preset time period and the first coding speed of the first device to the streaming media data to be transmitted, and determining that the target network is in a congestion state when the data transmission delay of the target network in the preset time period is larger than a preset delay threshold.
And s64, if the target network is in a congestion state, acquiring the data transmission speed of the target network. The data transmission speed of the target network may be determined based on the transmission speed of the streaming media data by the target network over a plurality of historical time periods.
s65, the network device may send the data transmission speed of the target network to the first device.
And s66, the first equipment reduces the coding speed of the streaming media data to be sent according to the data transmission speed of the target network so as to reduce the speed of sending the streaming media data to the second equipment, thereby reducing the data quantity corresponding to the streaming media data sent to the target network and enabling the target network to quickly recover to a normal state.
