Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular, to a method, apparatus, device and computer-readable storage medium for message flow control. Background Art

[0002] With the development of communication technology, there are more and more types of applications relying on communication technology, such as online learning applications, game applications, and video applications. For any type of application, the corresponding functions of the application can be realized by transmitting the message of the application, thus generating corresponding message traffic.

[0003] In the related art, the message flow is controlled by setting the Internet access time for the device. Within the set Internet access time, the device can normally transmit messages of various applications. When the set Internet access time is exceeded, the device stops transmitting messages of various applications. It is not difficult to see that the message flow control achieved by setting the Internet access time is aimed at the overall message flow of the device, so the flexibility is poor and the control accuracy is not high. Summary of the invention

[0004] The present application proposes a method, apparatus, device and computer-readable storage medium for message flow control, which are used to control message flow, improve the flexibility and accuracy of message flow control, and have a finer control granularity.

[0005] In a first aspect, a method for message flow control is provided, and the method is introduced by taking a first device executing the method as an example. The first device obtains a first message, for example, the first message is an Internet protocol (IP) message; the first message carries indication information for indicating the type of the first message. In response to the type of the first message being a type that requires flow control, the first device performs flow control on the first message according to a processing method corresponding to the type of the first message. For example, the type of the identified first message is a game type, and the game type is a type that requires flow control, and the first device controls the message flow of the first message according to the processing method corresponding to the game type.

[0006] In the method of message flow control provided by the technical solution, the first device can directly determine the type of the first message based on the indication information carried by the first message that can indicate the type of the first message, without comparing other contents of the first message. The solution is highly efficient in determining the type of the first message. Secondly, in the case where the type of the first message is a type that requires flow control, it is possible to implement flow control by adopting corresponding processing methods for different types of messages. Since the solution adopts a corresponding processing method for the message according to the type of the message, the solution is highly flexible, the flow control is highly accurate, and the control granularity is fine.

[0007] In one possible implementation, the types that require flow control include game types, and the first device performs flow control on the first message according to a processing method corresponding to the type of the first message, including: the first device performs flow control on the first message according to a processing method corresponding to the game type.

[0008] In a possible implementation, the game type is a first type of game or a second type of game, the first type of game is a game type with a real-time index higher than an index threshold, and the second type of game is a game type with a real-time index lower than an index threshold; the first device controls the flow of the first message according to the processing method corresponding to the game type, including: in response to the first type of game being the first type of game, the first device determines whether to discard the first message according to a reference ratio, the reference ratio being a specified ratio of discarding messages of the first type of game; or in response to the first type of game being the second type of game, the first device transmits the first message at a first rate, and the real-time index corresponding to the first rate is lower than the real-time index of the second type of game.

[0047] The terms used in the implementation mode of the present application are only used to explain the embodiments of the present application, and are not intended to limit the present application. The embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0048] The present invention provides a method for controlling packet flow. Figure 1 In the network scenario shown in Figure 1 As shown, the network scenario includes a first device 101, a second device 102, and a third device 103, wherein the second device 102 is a network device in the first transmission network, and the third device 103 is a network device in the second transmission network. The first device 101 and the second device 102 can exchange information through the first transmission network, and the first device 101 and the third device 103 can exchange information through the second transmission network to achieve message transmission.

[0049] For example, in the embodiment of the present application, the first device 101 includes but is not limited to a router, a switch, a server, etc., the second device 102 includes but is not limited to a router, a switch, a server, etc., and the third device 103 includes but is not limited to electronic devices such as a terminal. Figure 1 The network scenario shown may include multiple second devices 102 and / or multiple third devices 103. Figure 1 In the description, only one second device 102 and one third device 103 are taken as examples.

[0050] Combination Figure 1 In the network scenario shown in FIG. 1 , the method for controlling message flow provided in the embodiment of the present application is as follows: Figure 2 As shown, including but not limited to step 201 and step 202.

[0051] Step 201: A first device obtains a first message, where the first message carries indication information, where the indication information is used to indicate a type of the first message.

[0052] The first device receives the first message through the first transmission network, corresponding to Figure 1 In the network scenario shown, a first device receives a first message sent by a second device through a first transmission network.

[0053] In a possible implementation, the indication information is carried in the indication field, and the first message carries the indication information by carrying the indication field. Exemplarily, the type of the first message indicated by the indication information includes, but is not limited to: game type, video type, and education type. Exemplarily, the game type is a first type of game type or a second type of game type. Among them, the first type of game type is a game type whose real-time index is higher than the index threshold, for example, a multiplayer online battle arena (MOBA); the second type of game type is a game type whose real-time index is lower than the index threshold, for example, a role-playing game (RPG) or a card game. Among them, the real-time index includes an operation feedback delay, and the index threshold can be a set value based on experience. For example, if the index threshold is 50 milliseconds (ms), and the real-time index of the first type of game type is less than 50ms, then the real-time index of the first type of game type is higher than the index threshold, and the real-time index of the first type of game type is high; if the real-time index of the second type of game type is greater than 50ms, then the real-time index of the second type of game type is lower than the index threshold, and the real-time index of the second type of game type is low. Exemplarily, when the value of the indication field is 0x01, that is, the indication information is 0x01, it indicates that the type of the first message is the first category game type; when the value of the indication field is 0x02, that is, the indication information is 0x02, it indicates that the type of the first message is the second category game type; when the value of the indication field is 0x03, that is, the indication information is 0x03, it indicates that the type of the first message is the video type; when the value of the indication field is 0x04, that is, the indication information is 0x04, it indicates that the type of the first message is the education type.

[0054] Exemplarily, the first message is an IP message, and the first message includes an IP message header and an IP data portion. The structure of the IP message header is as follows: Figure 3As shown, the IP message header carries an indication field, which carries indication information, and the length of the indication field does not exceed 32 bits. When the length of the indication field is less than 32 bits, a padding value is added to the IP message header so that the sum of the length of the indication field and the length of the padding value is 32 bits. For example, the length of the indication field is 16 bits, the length of the padding value is 16 bits, and the padding value can be 0. Of course, the length of the indication field can also be 32 bits. When the length of the indication field is 32 bits, there is no need to add a padding value to the IP message header. In addition, the IP message header also includes: version, which is 4 bits long and is used to indicate the version of the IP protocol; header length, which is 4 bits long and is used to indicate the protocol header length of the message; service type, which is 8 bits long and is used to carry the priority information of the message; total length, which is 16 bits long and is used to indicate the byte length of the message; identification, which is 16 bits long and is used to identify segmented messages belonging to the same message; mark, which is 3 bits long and is used to indicate whether the message is a segmented message and whether the message can be segmented; segment offset, which is 13 bits long and is used to indicate the relative position of the segmented message in the source message; life time, which is 8 bits long and is used to control the loop process of the message; transport layer protocol, which is 8 bits long and is used to identify the transport layer protocol applied to the data part of the message; header checksum, which is 16 bits long and is used to ensure the integrity of the IP protocol header; source IP address, which is 32 bits long and is used to identify the device sending the message; destination IP address, which is 32 bits long and is used to identify the device receiving the message.

[0055] It should be noted that the type of the first message may also be other types. When the first message is an IP message, the structure of the IP message header may also be other structures carrying an indication field. Figure 3 The IP packet header structure shown is for illustration only and is not limited to this embodiment of the present application.

[0056] In a possible implementation, the first device determines the type of the first message according to the indication information. When the first message carries the indication information for indicating the type of the first message, the first device can directly determine the type of the first message through the indication information without comparing other contents of the first message, so the method of determining the type of the first message is more efficient. Exemplarily, the first device identifies the indication field carried by the first message, and the indication field carries the indication information; the first device identifies the indication information, and determines the type of the first message according to the identified indication information. For example, the identified indication information is 0x01, and according to the indication information, the type of the first message is determined to be the first type of game type; the identified indication information is 0x02, and according to the indication information, the type of the first message is determined to be the second type of game type; the identified indication information is 0x03, and according to the indication information, the type of the first message is determined to be the video type; the identified indication information is 0x04, and according to the indication information, the type of the first message is determined to be the education type. Since the indication information can directly indicate the type of the first message, the type of the message can be quickly determined through the indication information.

[0057] Step 202: In response to the type of the first message being a type that requires flow control, the first device performs flow control on the first message according to a processing method corresponding to the type of the first message.

[0058] Among them, the types that need to be flow controlled include but are not limited to game types, video types and educational types, wherein the game types are first-class game types or second-class game types. The types that need to be flow controlled can be configured in advance, for example, which types are configured in advance as types that need to be flow controlled according to different application scenarios. After configuring the types that need to be flow controlled, they can also be adjusted according to different application scenarios. The embodiment of the present application does not limit the configuration method and configuration timing of the types that need to be flow controlled.

[0059] Exemplarily, the first device matches the type of the first message with the type that needs to be flow controlled, and determines whether the type of the first message is the type that needs to be flow controlled. In response to the type of the first message successfully matching the type that needs to be flow controlled, the type of the first message is the type that needs to be flow controlled, and flow control is performed on the first message according to the processing method corresponding to the type of the first message. For example, the type of the first message is a game type, and in response to the game type being the type that needs to be flow controlled, the type of the first message successfully matches the type that needs to be flow controlled, and flow control is performed on the first message according to the processing method corresponding to the game type. Optionally, in response to the type of the first message failing to match the type that needs to be flow controlled, the type of the first message is not the type that needs to be flow controlled, and the first device does not perform flow control on the first message. Exemplarily, a successful match refers to consistent types, and a failed match refers to inconsistent types.

[0060] In one possible implementation, Figure 4 As shown, for first message types that require different flow control, the first device performs flow control on the first message according to the processing method corresponding to the type of the first message, including but not limited to the following three situations.

[0061] Case 1: The type of the first message is game type.

[0062] In the case where the type of the first message is a game type, the first device controls the flow of the first message according to the processing method corresponding to the game type. Since the game type is the first game type or the second game type, for situation one, in response to the type of the first message being the first game type, the first device determines whether to discard the first message according to the reference ratio, and the reference ratio is a specified ratio of discarding messages of the first game type. Among them, the reference ratio can be flexibly set according to experience or usage requirements, and the embodiment of the present application does not limit this. For example, if the reference ratio is 75%, then in every four first messages, the first device normally transmits three of them and discards one message. Therefore, by determining whether to discard the first message according to the reference ratio, the first device can save the processing time of the first device and improve the efficiency of message flow control while reducing the user's gaming experience. Of course, the reference ratio can also be 100%, that is, the first device discards all messages of the first game type, and the embodiment of the present application does not limit the reference ratio. By determining whether to discard the first message according to the reference ratio, the first device can reduce the message flow of transmitting the first message.

[0063] Exemplarily, in response to the type of the first message being the first type of game, before the first device determines whether to discard the first message according to a reference ratio, the method further includes: the first device monitors whether the message flow of the first message reaches a set threshold, and in response to the message flow of the first message reaching the set threshold, the first device determines whether to discard the first message according to the reference ratio. Among them, the set threshold can be flexibly set according to experience or usage requirements, and the embodiments of the present application are not limited to this. Since the real-time index of the first type of game is high, when the user plays the game of the first type of game, the message flow of the message generated by the game is usually high; when the user only opens the game interface of the game of the first type of game, but does not play the game, the message flow of the message generated by the game is usually low; by monitoring whether the message flow of the first message reaches the set threshold, the method is more flexible in controlling the message flow.

[0064] Optionally, in response to the type of the first message being a second type of game, the first device transmits the first message at a first rate, and the real-time index corresponding to the first rate is lower than the real-time index of the second type of game. Among them, the first rate can be flexibly set according to experience or usage requirements, and the embodiments of the present application are not limited to this. For example, the real-time index of the second type of game is 100ms, and the first device transmits the first message at a first rate corresponding to a real-time index of 200ms. By transmitting the first message at a first rate corresponding to a real-time index lower than the real-time index of the second type of game, when the user is playing a game of the second type of game, an operation delay will occur, reducing the user's gaming experience.

[0065] Case 2: The type of the first message is video type.

[0066] For situation 2, the first device performs flow control on the first message according to a processing method corresponding to the video type, including but not limited to steps 2021 and 2022.

[0067] Step 2021: The first device identifies the encoding type of the first message.

[0068] Exemplarily, the first message is an IP message, the transport layer protocol is a real-time transport protocol (RTP), and the IP data portion of the first message carries an RTP header and a payload. The RTP header carries a payload type (PT), and the payload carries encoding parameters and image frames. Figure 5In the RTP header shown, the PT length is 7 bits, which is used to indicate the encoding type adopted by the payload, for example, the encoding type is moving picture experts group (MPEG) 4 algorithm encoding or H264 algorithm encoding. In addition, the RTP header also includes: version (V), 2 bits in length, used to indicate the version of RTP; padding flag (P), 1 bit in length, used to indicate whether the end of the message needs to be padded with additional octets; extension flag (X), 1 bit in length, used to indicate that there is an extension header after the RTP header; contributing source (CSRC) counter (CC), 4 bits in length, used to indicate the number of CSRC identifiers; mark (M), 1 bit in length, used to allow marking of important events; sequence number (SN), 16 bits in length, used to identify the sequence number; timestamp (timestamp), 32 bits in length; synchronization source (SSRC) identifier, 32 bits in length, used to identify the synchronization source; CSRC identifier, 32 bits in length, used to identify the contributing source.

[0069] Step 2022: Based on the coding type, the first device identifies a forward predictive coding frame (P frame) in the first message, and the first device discards the P frame.

[0070] The first device identifies the P frame in the first message by identifying the coding parameters carried by the payload. Exemplarily, if the coding type is MPEG4 algorithm coding, the coding parameters include the frame start and the frame type adjacent to the frame start. For example, the frame start is 000001b6, and when the frame type is 00, it indicates that the image frame carried by the payload is an intra-frame coded frame (I frame); when the frame type is 01, it indicates that the image frame carried by the payload is a P frame; when the frame type is 02, it indicates that the image frame carried by the payload is a bidirectional predictive coded frame (B frame).

[0071] Exemplarily, if the encoding type is H264 algorithm encoding, the encoding parameters include a group of pictures (GOP), and the GOP has a frame structure. According to the frame structure of the GOP, the first device identifies the P frame in the first message. For example, the frame structure of the GOP is IBBPBPBBPBBBB, that is, the 4th image frame, the 7th image frame, the 10th image frame and the 13th image frame in the picture group are P frames. Exemplarily, the first device can discard a target number of P frames, and the target number can be flexibly set according to experience or usage requirements, and the embodiment of the present application does not limit this. For example, the frame structure of the GOP is the above-mentioned IBBPBBPBBPBBPBB, and the target number is 1. The first device can discard any one of the 4th image frame, the 7th image frame, the 10th image frame and the 13th image frame. Of course, the first device can also discard all P frames. By discarding the target number of P frames, it is possible to save the processing time of the first device and improve the efficiency of message flow control while reducing the user viewing experience.

[0072] Case 3: The type of the first message is education type.

[0073] For situation three, the first device performs flow control on the first message according to the processing method corresponding to the education type, including: the first device transmits the first message at a second rate, and the second rate is higher than the initial transmission rate of the first message. Among them, the second rate can be flexibly set according to experience or usage requirements, and the embodiment of the present application is not limited to this. For example, the initial transmission rate of the first message is 10 megabits per second (Mbps), and the first device transmits the first message at a second rate, and the second rate is 12Mbps. By transmitting the first message at a rate higher than the initial transmission rate of the first message, the process will be smoother when the user receives online education, thereby improving the user experience.

[0074] In a possible implementation of the present application, the first device is provided with a flow control switch, and the flow control switch is used to control whether to execute the message flow control method provided in the embodiment of the present application, so that the flow control of the message is more in line with actual needs. Exemplarily, the first device can store flow control switch status information, and the flow control switch status information is used to indicate the flow control switch status. The flow control switch status includes an open state or a closed state. The open state means that the flow control is turned on, and the closed state means that the flow control is turned off. Therefore, the first device can obtain the flow control switch status by obtaining the flow control switch status information. For example, when the flow control switch status information is 0, it indicates that the flow control switch status is in the closed state; when the flow control switch status information is 1, it indicates that the flow control switch status is in the open state. Exemplarily, before step 202, the method also includes: the first device obtains the flow control switch status; in response to the flow control switch status being in the open state, the first device determines whether the type of the first message is a type that requires flow control.

[0075] In addition, the embodiment of the present application does not limit the timing of the first device acquiring the flow control switch state. For example, the flow control switch state can be periodically acquired, and the length of the cycle can be set based on the application scenario or experience. For example, the length of the cycle is one hour, and the first device acquires the flow control switch state every hour. Optionally, in addition to the method of periodically acquiring the flow control switch state, the acquisition of the flow control switch state can also be triggered according to the update of the flow control switch state. For example, when the flow control switch is updated from the closed state to the open state, the first device detects the update instruction of the flow control switch state, and the first device executes the operation of acquiring the flow control switch state. Or, after the flow control switch is turned on, if the flow control switch is turned off again, the flow control switch state is updated from the open state to the closed state, then the first device acquires the update instruction of the flow control switch state, and the first device executes the operation of acquiring the flow control switch state based on the update instruction. In addition, the first device can display a prompt message, and the prompt message is used to prompt the user whether to turn on the flow control switch. For example, the first device periodically displays the prompt message, and the prompt cycle can be set according to the use needs.

[0076] The method provided in the embodiment of the present application can directly determine the type of the first message according to the indication information carried by the first message that can indicate the type of the first message, without comparing other contents of the first message. The scheme of the present application is more efficient in determining the type of the first message. Secondly, in the case where the type of the first message is a type that requires flow control, it is possible to implement flow control by adopting corresponding processing methods for different types of messages. Since the scheme of the present application adopts a corresponding processing method for the message according to the type of the message, the scheme of the present application is more flexible, the flow control is more accurate, and the control granularity is finer.

[0077] Combination Figure 1 The network scenario shown, Figure 6 A flowchart of a method for message flow control provided by another exemplary embodiment of the present application is shown. Figure 2 In the embodiment shown, steps 203 to 206 are added before step 201 to enable the first message to carry indication information for indicating the type of the first message. Figure 6 As shown, the method for message flow control includes the following steps.

[0078] Step 203: The second device receives the second message.

[0079] Wherein, the second device receives the second message through the first transmission network. Exemplarily, the second message includes the first information, and the first information may include at least one of the five-tuple information and the priority information. Wherein, the five-tuple information includes the source IP address, the source port, the destination IP address, the destination port and the transport layer protocol. Wherein, the transport layer protocol includes but is not limited to: any one of the transmission control protocol (TCP), the user datagram protocol (UDP) and RTP. The priority information includes but is not limited to: any one of the IP priority, the type of service (TOS) priority and the differentiated services code point (DSCP) priority; wherein the types of DSCP priority include: class selector (CS), expedited forwarding (EF), assured forwarding (AF) 1 to 4 and default (BE).

[0080] Exemplarily, the second message is an IP message, and the second message includes an IP message header and an IP data portion. The IP message header carries the source IP address, the destination IP address, the transport layer protocol, and the priority information, and the IP data portion carries the source port and the destination port. The structure of the IP message header is as follows: Figure 7 As shown, the various parts of the IP packet header are Figure 3 The corresponding parts of the IP message header shown in the figure have the same principle and will not be described here. It should be noted that when the second message is an IP message, the structure of the IP message header can also be other structures including the source IP address, the destination IP address, the transport layer protocol and the priority information. In the embodiment of the present application, only the second message is an IP message, and the IP message header is Figure 7 The IP packet header structure shown is for illustration only and is not limited to this embodiment of the present application.

[0081] Taking the example that the first information includes quintuple information and priority information, the following Table 1 is a table of the first information included in the second message provided in an embodiment of the present application, and each second message includes one first information in the following Table 1.

[0082] Table 1

[0083]

[0084] In the above Table 1, when the second message includes the first information numbered 1, the five-tuple information included in the first information includes the source IP address A1, the destination IP address B1, the source port C1, the destination port D1, and the transport layer protocol UDP, and the priority information included in the first information is AF3. When the second message includes other first information in Table 1, the principle is the same as that of the second message including the above-mentioned first information numbered 1, which will not be repeated here. It should be noted that the first information included in the second message shown in the above Table 1 is only the first information illustrated in the embodiment of the present application. For any second message, the second message may include other five-tuple information and / or priority information, which is not limited to the embodiment of the present application.

[0085] Step 204: The second device identifies the type of the second message.

[0086] Exemplarily, the second device obtains the first information of the second message, matches the first information with the second information in the model library, the model library includes multiple second information, each second information corresponds to a message type; in response to the first information successfully matching any second information in the multiple second information, the type of the message corresponding to any second information is determined as the type of the second message. Exemplarily, the model library is an embedded artificial intelligence (eAI) model library. The following Table 2 shows the eAI model library.

[0087] Table 2

[0088]

[0089] In the above Table 2, the model library of the eAI includes multiple second information, and each second information includes quintuple information and priority information. The quintuple information and priority information included in the second information are respectively the same as the quintuple information and priority information included in the first information in the above Table 1, and will not be repeated here. In the above Table 2, the type of message corresponding to the second information numbered 1 is the first type of game type, and the real-time index of the first type of game type is high. It should be noted that the model library of the eAI shown in the above Table 2 can include more types of messages. For any type of message, more second information can correspond. For example, for the first type of game, three or more second information can correspond. The embodiment of the present application does not limit this.

[0090] Exemplarily, matching the first information with the second information in the model library includes but is not limited to the following three situations.

[0091] Case 1: The first information only includes quintuple information.

[0092] For situation one, the five-tuple information included in the first information is matched with the five-tuple information included in the second information; in response to the five-tuple information included in the first information and the five-tuple information included in the second information being matched successfully, the second information is used as the second information that has been matched successfully. For example, in response to the five-tuple information included in the first information being the same as the five-tuple information included in the second information, the first information is matched successfully with the second information. For example, the five-tuple information included in the first information is source IP address A1, destination IP address B1, source port C1, destination port D1, and transport layer protocol UDP; the five-tuple information included in the first information is matched with the second information in the model library, in response to the five-tuple information of the first information being matched successfully with the second information including the five-tuple information of source IP address A1, destination IP address B1, source port C1, destination port D1, and transport layer protocol UDP, the type of the message corresponding to the second information is the first type of game type, and the first type of game type is determined as the type of the second message.

[0093] Optionally, in response to any part of the five-tuple information included in the first information being different from the corresponding part of the five-tuple information included in the second information, the first information fails to match the second information. For example, the five-tuple information included in the first information is source IP address A1, destination IP address B2, source port C1, destination port D1, and transport layer protocol UDP; the five-tuple information included in the second information is source IP address A1, destination IP address B1, source port C1, destination port D1, and transport layer protocol UDP; in response to the destination IP address in the first information being different from the target IP address in the second information, the first information fails to match the second information.

[0094] Case 2: The first information only includes priority information.

[0095] For situation 2, the priority information included in the first information is matched with the priority information included in the second information; in response to the priority information included in the first information and the priority information included in the second information being successfully matched, the second information is used as the second information that has been successfully matched. For example, in response to the priority information included in the first information being the same as the priority information included in the second information, the first information is successfully matched with the second information. Optionally, in response to the priority information included in the first information being different from the priority information included in the second information, the first information fails to match with the second information.

[0096] Case 3: The first information includes quintuple information and priority information.

[0097] For situation three, the five-tuple information included in the first information is matched with the five-tuple information included in the second information; in response to the five-tuple information included in the first information and the five-tuple information included in the second information being matched successfully, the priority information included in the first information is matched with the priority information included in the second information; in response to the priority information included in the first information and the priority information included in the second information being matched successfully, the second information is used as the second information that has been successfully matched. Among them, the manner of matching the five-tuple information included in the first information with the five-tuple information included in the second information, and the manner of matching the priority information included in the first information with the priority information included in the second information are respectively the same as the manner of matching in situation one and situation two, and are not repeated here. In addition, the priority information included in the first information may also be matched with the priority information included in the second information first; in response to the priority information included in the first information and the priority information included in the second information being matched successfully, the five-tuple information included in the first information is matched with the five-tuple information included in the second information; in response to the five-tuple information included in the first information and the five-tuple information included in the second information being matched successfully, the second information is used as the second information that has been successfully matched.

[0098] Step 205: The second device adds indication information to the second message to generate a first message, where the indication information is used to indicate the type of the first message.

[0099] Exemplarily, the second message is an IP message, and the second device adds an indication field to the IP message header of the second message, and carries the indication information through the indication field; based on the IP message header with the indication field added, the second device generates the first message. Exemplarily, the structure of the IP message header with the indication field added, the way the indication field carries the indication information, and the way the indication information indicates the type of the first message are respectively the same as the structure of the IP message header, the way the indication field carries the indication information, and the way the indication information indicates the type of the first message in step 201, and are not repeated here.

[0100] It should be noted that the second message may also be other types of messages. When the second message is an IP message, the structure of the IP message header may also be other structures carrying indication fields, which is not limited in the embodiments of the present application.

[0101] Step 206: The second device sends a first message to the first device.

[0102] The second device sends the first message to the first device through the first transmission network.

[0103] In a possible implementation, the method further includes: the second device receives a third message, the type of the third message is different from the types of messages corresponding to multiple second information in the model library, and the second information corresponding to the type of the third message is added to the model library. Since the type of the third message is different from the type of the message corresponding to the second information in the model library, it means that there is no second information corresponding to the type of the third message in the model library, and thus by adding the second information corresponding to the type of the third message to the model library, the model library can be made more complete, that is, the second information in the model library is made more comprehensive, so that more types can be identified when the model library is used later.

[0104] The method provided in the embodiment of the present application generates a first message carrying indication information for indicating the type of the first message through a second device, and then sends the first message to the first device. The first device can directly determine the type of the first message based on the indication information without comparing other contents of the first message. The scheme of the present application is highly efficient in determining the type of the first message. Secondly, in the case where the type of the first message is a type that requires flow control, it is possible to implement flow control by adopting corresponding processing methods for different types of messages. Since the scheme of the present application adopts a corresponding processing method for the message according to the type of the message, the scheme of the present application is highly flexible, the flow control is highly accurate, and the control granularity is fine.

[0109] Optionally, the type requiring flow control includes a video type, and the control module 802 is used to identify the coding type of the first message; based on the coding type, identify the forward prediction coding frame in the first message, and discard the forward prediction coding frame.

[0110] Optionally, the type requiring flow control includes an education type, and the control module 802 is used to transmit the first message at a second rate, where the second rate is higher than an initial transmission rate of the first message.
