Similarly, the second device may send data to the first device through the target network; for example, the second device may send the second data to the target network, which forwards the second data to the first device, where the second data may be any data that the second device needs to send to the first device. Network devices may specifically include, but are not limited to: gateway devices, routers, switches, base stations, etc. The first data or the second data may refer to audio-video data (e.g., video conferencing data, video live data), image data, game application data, and so forth. The target network may refer to a Wireless network or a wired network, and the Wireless network may include a mobile data network or a Wireless Fidelity (WiFi) network. In an embodiment, a process of data exchange between a first device and a second device is described by taking an example that the first device sends first data to the second device through a target network, and as shown in fig. 2, the process of data exchange includes the following steps s1 to s 5.

The attribute information includes an identifier of the first device, an identifier of the second device, a data transmission time, and the like, where the identifier may refer to an IP address, a telephone number, a serial number, or the like of the device.
s3, the first device sends the data forwarding request to the target network.
In steps s1-s3, to improve the data transmission security of the target network and save data transmission resources, the first device may encode the first data to be sent by using a preset encoding algorithm, 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 (ADPCM), 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.

(4) And adjusting the speed of the first equipment for sending data to the second equipment according to the data transmission speed. The congestion control method can rapidly determine whether the target network is in the congestion state according to the data congestion amount in the target network, and when the target network is in the congestion state, the speed of sending data to the second equipment by the first equipment 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 rapidly recovered to the normal state, the communication service in the target network can be ensured to be recovered to the normal state, and the user experience is improved.
Based on the above description of the data processing system, please refer to fig. 3, fig. 3 is a data processing method according to an embodiment of the present invention, which 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 a first device sends data to a second device through a target network, obtaining the data blocking amount of the target network, wherein the data blocking amount comprises the data amount to be forwarded to the second device in a transmission layer of the target network and the data amount cached 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 and connects to the available network, and the available network is determined as a target network. The available network herein may refer to a network that can be used to transmit data, wherein when the number of available networks is plural, a network with the best communication quality may be taken 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 obtain a data congestion amount of the target network. Here, the data blocking amount includes a data amount to be forwarded to the second device in the transport layer of the target network, and a data amount buffered by the application layer of the target network, that is, the data blocking amount may be a sum of the data blocking amount of the transport layer of the target network (that is, the data amount to be forwarded to the second device in the transport layer of the target network) and the data buffering amount of the application layer of the target network, that is, the data blocking amount is a data amount corresponding to data to be forwarded to the second device by the target network in the data sent by the first device.
And S102, determining the data transmission state of the target network according to the data blocking amount.
The more the data blocking amount of the target network is, the more the data amount which needs to be forwarded by the target network is, namely the probability that the target network is in a congestion state is higher; the smaller the data blocking amount of the target network is, the smaller the data amount that the target network needs to forward is, i.e. the probability that the target network is in a congestion state is smaller. Therefore, the network device may determine the data transmission status of the target network according to the data blocking amount, where the data transmission status includes a congestion status, a saturation status, and a non-saturation status.
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 the congestion state, it indicates that there is an excessive amount of data to be forwarded in the target network, and if the target network is in the congestion state for a long time, it is easy to cause interruption of the communication service in the target network. Accordingly, 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.
And S104, adjusting the speed of the first device for sending data to the second device according to the data transmission speed of the target network.
The network device may adjust the speed at which the first device sends data to the second device according to the data transmission speed of the target network, that is, the speed at which the first device sends data to the second device may be reduced according to the data transmission speed of the target network. Therefore, the data volume sent to the target network by the first equipment can be reduced, the data blocking volume of the target data network is further reduced, and the target network can be quickly recovered 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 the congestion state can be verified through the data blocking amount of the target network, whether the target network is in the congestion state is not required to be verified according to the data receiving time, and the blocking problem of the target network can be quickly found; when the target network is in the congestion state, the speed of sending data to the second device by the first 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 a normal state, and the user experience is improved.
In one embodiment, step S102 may include steps S11-S12 as follows.
And s11, determining the data transmission delay of the target network in a preset time period according to the data blocking amount.
s12, 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 the congestion state.
In steps s11 to s12, in order to improve the accuracy of determining the data transmission state of the target network, the network device may determine, according to the data congestion amount, a data transmission delay of the target network within a preset time period, where the data transmission delay is small, which indicates that the data transmission speed of the target network is fast and the target network is not stuck; the data transmission delay is large, which indicates that the data transmission speed of the target network is low and the target network has a jamming problem. Therefore, if the data transmission delay of the target network in the preset time period is greater than the preset delay threshold, it is determined that the target network is in the congestion state.
In one embodiment, step s11 may include steps s 21-s 22 as follows.
s21, obtaining the first encoding speed of the first device in the preset time period, and the 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 s 21-s 22, the network device may obtain 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, where the first encoding speed may be transmitted from the first device to the network device. Optionally, the network device may obtain an average value of the coding speed of the first device in a preset time period, determine the average value as the first coding 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 any time period within a time period in which the first device transmits data to the second device. 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 obtain, by using a preset time interval as a sampling unit, first encoding speeds of the first device at multiple times within a preset time period, and obtain, by using the preset time interval as the sampling unit, data congestion amounts of the target network at the multiple times within the preset time period. And determining the quotient of the data blocking amount and the first coding speed at each moment 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 value.
In one embodiment, step S103 may include steps S31-S32 as follows.
And 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 s 31-s 32, since the target network is affected by external interference or its performance, the fluctuation of the data transmission speed of the target network is relatively large, and if the speed of the first device sending data is adjusted according to the current real-time speed of the target network, the target network is likely to be in a congestion state frequently. Therefore, the network device may obtain the data transmission speeds of the target network in a plurality of historical time periods, and perform weighted summation on the data transmission speeds in the plurality of historical time periods to obtain the data transmission speed of the target network. Wherein, the data transmission speed of the target network can be expressed by formula (1).
Wherein, ARnData transmission speed, AR, for the target networkkThe data transmission speed of the target network in the kth historical time period is shown, n represents the number of the historical time periods, x represents a weight coefficient, x belongs to (0, 1), and the weight coefficient can refer to a default value of the network equipment or can be set by a user.
In one embodiment, step S104 may include steps S41-S42 as follows.
s41, obtaining the decoding speed of the second device to the received data and the change rate 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 s 41-s 42, the network device can obtain the decoding speed of the second device for the received data and the change rate 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 change rate is larger, the change speed of the data transmission speed of the target network is faster, namely, the data transmission speed fluctuation of the target network is larger; the smaller the change rate is, the slower the change of the data transmission speed of the target network is, i.e., the data transmission speed of the target network has less fluctuation. The decoding speed of the second device affects the data quality, that is, if the decoding speed of the second device is high, the data received by the second device can be decoded in time, and the probability of the data being abnormal is low; if the decoding speed of the second device is low, the data received by the second device cannot be decoded in time, and the data redundancy has abnormal problems such as jamming or code messing, that is, the probability of the data abnormality is high. Therefore, the network device may determine a minimum speed value from the data transmission speed and the decoding speed of the target network, and adjust the speed at which the first device sends data to the second device according to the minimum speed value and the change rate. Therefore, the target network can be recovered to be normal quickly, and abnormal problems such as blocking and the like of data in the second equipment can be avoided. Wherein the minimum speed value can be expressed by formula (2).
SR＝min(ARn,CRn) (2)
Wherein, CR in the formula (2)nThe decoding speed of the second device may be a decoding speed reported by the second device to the network device; SR is the minimum velocity value.
In this embodiment, step s43 may include steps s 51-s 52 as follows.
s51, calculating a second encoding speed according to the minimum speed value and the change rate.
s52, sending the second encoding speed to the first device, and enabling the first device to adjust the encoding speed of the first device according to the second encoding speed, so as to adjust the speed of sending data to the second device by the first device.
In steps s51 to s52, since the data transmission speed of the target network stores the volatility, the network device may calculate a second encoding speed according to the minimum speed value and the change rate, and transmit 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, so that the second device reduces the encoding speed of the data to be transmitted, which can reduce the speed of the data transmitted from the first device to the second device. Wherein the second encoding speed can be expressed by formula (3).
RR＝SR·(1-μ) (3)
Where RR in the formula (3) is the second coding 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: and if the target network is recovered to the normal state, sending the first coding speed to the first equipment, so that the first equipment adjusts the coding speed of the first equipment according to the first coding speed to adjust the speed of sending data to the second equipment by the first equipment.
The first coding speed is the coding speed of the first device when the target network is in a normal state, the second coding speed is the coding speed of the first device when the target network is in a congestion state, the first coding speed is greater than the second coding speed, and the normal state can be a saturated state or an unsaturated state. If the target network returns to the normal state, indicating that the data blocking amount in the target network is less or zero, the first device may be controlled to encode the data to be transmitted at a higher encoding speed, so as to improve the transmission efficiency of the data. That is, the network device may send the first coding speed to the first device, so that the first device codes the data to be sent according to the first coding 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 of transmitting audio and video data (such as video conference data and video live broadcast data), image data, game application data and the like. The following describes the data processing method in the embodiment of the present invention in detail by taking an example of sending streaming media data from a first device to a second device. The streaming media data may be data transmitted in a target network by using a streaming transmission method, and the streaming transmission method may specifically be that the first device issues the acquired streaming media data to the target network while acquiring the streaming media data, and the target network sends the acquired streaming media data to the second device in real time, and the second device may display the streaming media data to know the data acquired by the first device in real time. The streaming media data may specifically refer to video live broadcast data, such as event live broadcast data, teaching live broadcast data, game live broadcast data, and the like. As shown in fig. 4, the data processing method may include the following steps s61-s 63.
s61, the first device may send the streaming media data to the second device through the target network. The first device adopts the streaming media data, and sends the collected streaming media data to the target network while collecting the streaming media data, and the target network forwards the collected 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 the above steps s1 to s 5.
s62, in the process of the first device sending the streaming media data to the second device through the target network, the network device may obtain the data blocking amount in the target network. Here, the data blocking amount is a data amount corresponding to streaming media data, which is 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 a data amount corresponding to the streaming media data cached 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 based on the amount of data congestion of the target network. If the data blocking amount of the target network is large, it indicates that a large amount of streaming media data in the target network is not forwarded in time, and therefore, when the data blocking amount of the target network is larger than a preset data amount threshold, it is determined that the target network is in a congestion state. Or, determining the data transmission delay of the target network in a 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 streaming media data to be sent by the first device, 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 greater than a preset delay threshold.
s64, if the target network is in the 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.
s66, the first device reduces the encoding 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 device, thereby reducing the data volume corresponding to the streaming media data sent to the target network, so that the target network can be quickly restored to a normal state.
