Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of explanation only of the examples of the present application and is not intended to be limiting of the present application. Embodiments of the present invention will be described below with reference to the accompanying drawings.

The embodiment of the application provides a method for controlling message flow, which can be applied to a network scene shown in fig. 1. As shown in fig. 1, the network scenario includes a first device 101, a second device 102, and a third device 103, where the second device 102 is a network device in a first transmission network, and the third device 103 is a network device in a second transmission network. The first device 101 and the second device 102 can perform information interaction through a first transmission network, and the first device 101 and the third device 103 can perform information interaction through a second transmission network, so as to realize transmission of a message.

Illustratively, the first device 101 in the embodiment of the present application includes, but is not limited to, a router, a switch, a server, and the like, the second device 102 includes, but is not limited to, a router, a switch, a server, and the like, and the third device 103 includes, but is not limited to, an electronic device such as a terminal. It should be noted that the network scenario shown in fig. 1 may include a plurality of second devices 102 and/or a plurality of third devices 103, and only one second device 102 and one third device 103 are illustrated in fig. 1 as an example.

With reference to the network scenario shown in fig. 1, the method for controlling packet flow according to the embodiment of the present application is shown in fig. 2, and includes, but is not limited to, step 201 and step 202.

Step 201, a first device obtains a first message, where the first message carries indication information, and the indication information is used to indicate a type of the first message.

The first device receives the first packet through the first transmission network, and in the network scenario shown in fig. 1, the first device receives the first packet sent by the second device through the first transmission network.

In a possible implementation manner, the indication information is carried in an indication field, and the first packet carries the indication information by carrying the indication field. Illustratively, the type of the first packet indicated by the indication information includes but is not limited to: a game type, a video type, and an education type, illustratively, the game type is a first game type or a second game type. Wherein, the first type of game type is a game type with a real-time index higher than an index threshold, for example, multiplayer Online Battle Arena (MOBA); the second type of game is a game type with a real-time indicator below an indicator threshold, such as a role-playing game (RPG) or a card-type game. The real-time index includes an operation feedback delay, and the index threshold may be an empirically set value. 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, 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 indicator of the second type of game is greater than 50ms, the real-time indicator of the second type of game is less than the indicator threshold, and the real-time indicator of the second type of game is low. Exemplarily, when the value of the indication field is 0x01, that is, when the indication information is 0x01, it indicates that the type of the first message is the first type game type; when the value of the indication field is 0x02, namely the indication information is 0x02, the type of the first message is represented as a second game type; when the value of the indication field is 0x03, that is, the indication information is 0x03, the type of the first message is represented as a 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.

Illustratively, the first packet is an IP packet, and the first packet includes an IP packet header and an IP data portion. The structure of the IP packet header is shown in fig. 3, the IP packet header carries an indication field, the indication field 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 32bit, a padding value is added in the IP packet header, so that the sum of the length of the indication field and the length of the padding value is 32bit, for example, the length of the indication field is 16bit, the length of the padding value is 16bit, and the padding value may be 0. Of course, the length of the indication field may also be 32bit, and when the length of the indication field is 32bit, it is not necessary to add a padding value in the IP packet header. In addition, the IP packet header further includes: version with 4bit length for representing IP protocol version; the length of the header is 4 bits, and the header is used for indicating the length of a protocol header of the message; the service type is 8 bits in length and is used for carrying the priority information of the message; the total length is 16 bits and is used for representing the byte length of the message; the identifier is 16 bits in length and is used for identifying the segmented messages belonging to the same message; marking, wherein the length of the marking is 3 bits, and the marking is used for indicating whether the message is a segmented message or not and whether the message can be segmented or not; the segment offset is 13 bits in length and is used for indicating the relative position of the segment message in the source message; the survival time is 8 bits in length and is used for controlling the loop process of the message; the transmission layer protocol is 8 bits in length and is used for identifying the transmission layer protocol applied to the data part of the message; the header checksum, the length of which is 16 bits, is used for ensuring the integrity of the IP protocol header; a source IP address, the length of which is 32 bits (bit), for identifying a device for sending a message; the destination IP address is 32 bits in length and is used for identifying equipment for receiving the message.

It should be noted that the type of the first packet may also be other types, and when the first packet is an IP packet, the structure of the IP packet header may also be other structures that carry the indication field. In the embodiment of the present application, only the first message is an IP message, and an IP message header is an example of an IP message header structure shown in fig. 3, which is not limited in the embodiment of the present application.

In a possible implementation manner, the first device determines the type of the first packet according to the indication information. When the first message carries indication information used 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 that the mode for determining the type of the first message is higher in efficiency. Exemplarily, the first device identifies an indication field carried by the first packet, where the indication field carries 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 a first type game type; the identified indication information is 0x02, and the type of the first message is determined to be a second type game type according to the indication information; the identified indication information is 0x03, and the type of the first message is determined to be a video type according to the indication information; the identified indication information is 0x04, and the type of the first message is determined to be the education type according to the indication information. Since the indication information can directly indicate the type of the first packet, the type of the packet can be determined quickly through the indication information.

Step 202, in response to that the type of the first packet is the type that needs to perform flow control, the first device performs flow control on the first packet according to the processing mode corresponding to the type of the first packet.

The types of flow control that needs to be performed include, but are not limited to, game types, video types, and education types, wherein the game types are a first game type or a second game type. The type of the flow control to be performed can be configured in advance, for example, which type is configured in advance as the type of the flow control to be performed according to different application scenarios. After the types which need to perform flow control are configured, adjustment can be performed according to different application scenarios, and the configuration mode and the configuration time of the types which need to perform flow control are not limited in the embodiment of the application.

Illustratively, the first device matches the type of the first packet with the type that needs to perform flow control, and determines whether the type of the first packet is the type that needs to perform flow control. And in response to the successful matching of the type of the first message and the type which needs to perform flow control, if the type of the first message is the type which needs to perform flow control, performing flow control on the first message according to a processing mode corresponding to the type of the first message. For example, the type of the first message is a game type, and in response to that the game type is a type requiring flow control, the type of the first message is successfully matched with the type requiring flow control, and flow control is performed on the first message according to a processing mode corresponding to the game type. Optionally, in response to that the type of the first packet fails to match the type that needs to perform flow control, the type of the first packet is not the type that needs to perform flow control, and the first device does not perform flow control on the first packet. Illustratively, the matching success refers to the consistent type, and the matching failure refers to the inconsistent type.

In a possible implementation manner, as shown in fig. 4, as for the type of the first packet being a different type that requires flow control, the first device performs flow control on the first packet according to the processing manner corresponding to the type of the first packet, which includes but is not limited to the following three cases.

In case one, the type of the first message is a game type.

And under the condition that the type of the first message is the game type, the first equipment performs flow control on the first message according to a processing mode corresponding to the game type. As the game type is the first game type or the second game type, in response to the first message being the first game type, the first device determines whether to discard the first message according to a reference proportion, where the reference proportion is a designated proportion for discarding the first game type message, in case one. The reference proportion can be flexibly set according to experience or use requirements, and is not limited in the embodiment of the application. For example, if the reference ratio is 75%, the first device normally transmits three messages in every four first messages, and discards one message. Therefore, the first device determines whether to discard the first message according to the reference proportion, so that the processing time of the first device can be saved and the message flow control efficiency can be improved while the user game experience is reduced. Of course, the reference ratio may 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 packet according to the reference ratio, the first device can reduce the packet flow for transmitting the first packet.

Illustratively, 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 a reference ratio, and the method further includes: the first equipment monitors whether the message flow of the first message reaches a set threshold value, and in response to the fact that the message flow of the first message reaches the set threshold value, the first equipment determines whether to discard the first message according to a reference proportion. The set threshold value can be flexibly set according to experience or use requirements, and the embodiment of the application is not limited to this. Because the real-time index of the first game type is high, when a user plays the first game type, the message flow of the message generated by the game is usually high; when a user only opens a game interface of a first type of game type game but does not play the game, the message flow of a message generated by the game is usually low; by monitoring whether the message flow of the first message reaches the set threshold value, the method is more flexible in controlling the message flow.

Optionally, in response to that the type of the first packet is a second type of game type, the first device transmits the first packet according to a first rate, where a real-time index corresponding to the first rate is lower than a real-time index of the second type of game type. The first rate may be flexibly set according to experience or usage requirements, which is not limited in the embodiment of the present application. For example, the second type of game has a real-time indicator of 100ms, and the first device transmits the first message at a first rate corresponding to a real-time indicator of 200 ms. By transmitting the first message at the first rate at which the corresponding real-time index is lower than the real-time index of the second game type, when the user plays the second game type, operation delay occurs, and game experience of the user is reduced.

And in the second case, the type of the first message is a video type.

For the second case, the flow control of the first packet by the first device according to the processing mode corresponding to the video type includes, but is not limited to, step 2021 and step 2022.

Step 2021, the first device identifies the encoding type of the first packet.

Illustratively, the first packet is an IP packet, the transport layer protocol is a real-time transport protocol (RTP), and the IP data portion of the first packet carries an RTP header and a payload. The RTP header carries a Payload Type (PT), and the payload carries coding parameters and an image frame. In the RTP header shown in fig. 5, the PT has a length of 7 bits and is used to indicate the coding type used by the payload, for example, the coding type is Moving Picture Experts Group (MPEG) 4 algorithm coding or H264 algorithm coding. In addition, the RTP head further comprises: version (V), 2bit long, used to represent the version of RTP; a filling mark (P) with the length of 1bit is used for indicating whether the tail part of the message needs to be filled with an extra octet or not; an extension mark (X) with the length of 1bit is used for indicating that an extension header is arranged behind an RTP header; a Contract Source (CSRC) counter (CC) with a length of 4 bits, which is used for representing the number of CSRC identifiers; a marker (M) of length 1bit for allowing marking of significant events; a Sequence Number (SN), 16 bits long, for identifying the sequence number; a timestamp (timestamp) of 32 bits in length; a Synchronization Source (SSRC) identifier having a length of 32 bits for identifying a synchronization source; and the CSRC identifier has the length of 32 bits and is used for identifying the special offer information source.

Based on the coding type, the first device identifies a forward predictive coded frame (P-frame) in the first message, and the first device discards the P-frame, step 2022.

And the first equipment identifies the P frame in the first message by identifying the coding parameter carried by the load. Illustratively, if the encoding type is MPEG4 algorithm encoding, the encoding parameters include a frame start and a frame type adjacent to the frame start, for example, when the frame start is 000001b6 and the frame type is 00, the image frame carried by the load is an intra-coded frame (I frame); when the frame type is 01, the image frame carried by the load is a P frame; when the frame type is 02, the image frame carried by the load is a bidirectional predictive coded frame (B frame).

Illustratively, if the encoding type is H264 algorithm encoding, the encoding parameters include a group of pictures (GOP), and the GOP has a frame structure. The first device identifies a P frame in the first message based on the frame structure of the GOP. For example, the frame structure of the GOP is IBBPBBPBBPBBPBB, i.e., the 4 th image frame, the 7 th image frame, the 10 th image frame, and the 13 th image frame in the group of pictures are P frames. Illustratively, the first device may discard a target number of P frames, where the target number may be flexibly set according to experience or usage requirements, and this is not limited in this embodiment of the present application. For example, the frame structure of the GOP is IBBPBBPBBPBBPBB described above, the target number is 1, and the first device may discard any one of the 4 th image frame, the 7 th image frame, the 10 th image frame, and the 13 th image frame. Of course, the first device may also discard all P frames. By discarding the target number of P frames, the processing time of the first device can be saved and the efficiency of message flow control can be improved while the viewing experience of the user is reduced.

And in case three, the type of the first message is an education type.

For the third case, the first device performs flow control on the first message according to the processing mode corresponding to the education type, including: the first device transmits the first message according to a second rate, wherein the second rate is higher than the initial transmission rate of the first message. The second rate may be flexibly set according to experience or usage requirements, which is not limited in the embodiment of the present application. For example, the initial transmission rate of the first packet is 10 megabits per second (Mbps), the first device transmits the first packet according to the 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 is smoother when the user receives online education, and the user experience is improved.

In a possible implementation manner of the present application, the first device is provided with a flow control switch, and whether to execute the message flow control method provided in the embodiment of the present application is controlled by the flow control switch, so that the flow control of the message better meets the actual requirement. For example, the first device may store flow control switch state information indicating a flow control switch state, where the flow control switch state includes an on state or an off state, the on state indicates that flow control is turned on, and the off state indicates that flow control is turned off. Therefore, the first device can acquire the state of the flow control switch by acquiring the state information of the flow control switch. For example, when the flow rate control switch state information is 0, it indicates that the flow rate control switch state is an off state; when the flow rate control switch state information is 1, it indicates that the flow rate control switch state is on. Illustratively, prior to step 202, the method further comprises: the first equipment acquires the state of a flow control switch; and responding to the state of the flow control switch as an opening state, and determining whether the type of the first message is the type needing flow control or not by the first equipment.

In addition, the timing for the first device to acquire the state of the flow control switch is not limited in the embodiment of the present application, for example, the state of the flow control switch may be periodically acquired, the period length may be set based on an application scenario or experience, and for example, the period length is one hour, and the first device acquires the state of the flow control switch every other hour. Optionally, in addition to the manner of periodically acquiring the state of the flow control switch, the acquisition of the state of the flow control switch may be triggered according to an update of the state of the flow control switch. For example, when the flow control switch is updated from the off state to the on state, the first device detects an update instruction of the state of the flow control switch, and the first device performs an operation of acquiring the state of the flow control switch. Or after the flow control switch is turned on, if the flow control switch is turned off again and the state of the flow control switch is updated from the on state to the off state, the first device acquires an update instruction of the state of the flow control switch, and the first device executes an operation of acquiring the state of the flow control switch based on the update instruction. In addition, the first device may display a prompt message for prompting the user whether the flow control switch needs to be turned on. For example, the first device periodically displays the prompt message, and the prompt period can be set according to the use requirement.

According to the method provided by the embodiment of the application, the type of the first message can be directly determined according to the indication information which is carried by the first message and can indicate the type of the first message, and other contents of the first message do not need to be compared. Secondly, under the condition that the type of the first message is the type which needs flow control, the flow control can be realized by adopting corresponding processing modes for different types of messages. According to the scheme of the application, the message is processed in a corresponding mode according to the type of the message, so that the scheme of the application has high flexibility, high flow control accuracy and fine control granularity.

With reference to the network scenario shown in fig. 1, fig. 6 shows a flowchart of a method for controlling packet flow according to another exemplary embodiment of the present application. Based on the embodiment shown in fig. 2, step 203 to step 206 are added before step 201, so that the first packet can carry indication information for indicating the type of the first packet. As shown in fig. 6, the method for controlling packet flow includes the following steps.

Step 203, the second device receives the second message.

And the second equipment receives the second message through the first transmission network. Illustratively, the second packet includes first information, which may include at least one of quintuple information and priority information. The quintuple information includes a source IP address, a source port, a destination IP address, a destination port and a transport layer protocol. Transport layer protocols include, but are not limited to: a Transmission Control Protocol (TCP), a User Datagram Protocol (UDP), and RTP. Priority information includes, but is not limited to: any one of an IP priority, a type of service (TOS) priority, and a Differentiated Services Code Point (DSCP) priority; wherein, the types of DSCP priority include: class Selector (CS), expedited Forwarding (EF), assured Forwarding (AF) levels 1 to 4, and default (BE).

Illustratively, the second packet is an IP packet, and the second packet includes an IP packet header and an IP data portion. The IP message header carries a source IP address, a destination IP address, a transport layer protocol and priority information, and the IP data part carries a source port and a destination port. The structure of the IP header is shown in fig. 7, and the principle of each part of the IP header is the same as that of the corresponding part in the IP header shown in fig. 3, and is not described again here. It should be noted that, when the second packet is an IP packet, the structure of the IP packet header may also be another structure including a source IP address, a destination IP address, a transport layer protocol, and priority information. In the embodiment of the present application, only the second message is used as an IP message, and the IP message header is an example of the IP message header structure shown in fig. 7, which is not limited in the embodiment of the present application.

Taking the first information including quintuple information and priority information as an example, as shown in the following table one, each second message includes one piece of first information in the following table one.

Watch 1

In the first table, when the second packet 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. The principle that the second message includes the first information with the number 1 is the same when the second message includes other first information in the table one, and details are not repeated here. It should be noted that the first information included in the second message shown in the table one is only the first information illustrated in the embodiment of the present application. For any second packet, the second packet may include other five-tuple information and/or priority information, which is not limited in this embodiment of the present application.

And step 204, the second equipment identifies the type of the second message.

Exemplarily, the second device obtains first information of a second message, matches the first information with second information in a model base, where the model base includes a plurality of second information, and each second information corresponds to a type of the message; and determining the type of the message corresponding to any second information as the type of the second message in response to the first information being successfully matched with any second information in the plurality of second information. Illustratively, the model library is a model library of embedded artificial intelligence (eAI). The library of models is eAI as shown in table two below.

Watch two

In table two above, the model library of eAI includes a plurality of second information, each of which includes quintuple information and priority information. The quintuple information and the priority information included in the second information are respectively the same as the quintuple information and the priority information included in the first information in the first table in principle, and are not described again here. In the second table, the type of the message corresponding to the second information with the number of 1 is the first type game type, and the real-time performance index of the first type game type is high. It should be noted that the model library of eAI shown in table two above may include more message types, and any message type may correspond to more second information, for example, for a first game type, three or more second information may be corresponded, which is not limited in this embodiment of the present application.

Illustratively, the first information is matched with the second information in the model library, including but not limited to the following three cases.

Case one, the first information includes only five tuple information.

For the first case, matching quintuple information included in the first information with quintuple information included in the second information; and in response to the fact that the five-tuple information included in the first information is successfully matched with the five-tuple information included in the second information, taking the second information as the successfully matched second information. For example, in response to that the first information includes the same five-tuple information as the second information, the first information and the second information are successfully matched. For example, the first information includes five tuple information, which is a source IP address A1, a destination IP address B1, a source port C1, a destination port D1, and a transport layer protocol UDP; and matching quintuple information included in the first information with second information in a model library, and determining the first type of game as the type of the second message in response to that the matching of the quintuple information of the first information and the second information of the five tuple information including a source IP address A1, a destination IP address B1, a source port C1, a destination port D1 and a transport layer protocol UDP is successful, and the type of the message corresponding to the second information is the first type of game.

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, matching between the first information and the second information fails. For example, the first information includes five tuple information, which is a source IP address A1, a destination IP address B2, a source port C1, a destination port D1, and a transport layer protocol UDP; the second information comprises quintuple information including a source IP address A1, a destination IP address B1, a source port C1, a destination port D1 and a transport layer protocol UDP; and responding to the condition that the destination IP address in the first information is different from the target IP address in the second information, and the first information and the second information fail to be matched.

In case two, the first information includes only priority information.

For the second case, matching the priority information included in the first information with the priority information included in the second information; and in response to the priority information included in the first information and the priority information included in the second information being successfully matched, taking the second information as the successfully matched second information. For example, in response to the first information including the same priority information as the second information, the first information and the second information are successfully matched. Optionally, in response to that the priority information included in the first information is different from the priority information included in the second information, the first information and the second information fail to be matched.

Case three, the first information includes quintuple information and priority information.

For the third case, matching the quintuple information included in the first information with the quintuple information included in the second information; in response to the matching success of the five-tuple information included in the first information and the five-tuple information included in the second information, matching priority information included in the first information with priority information included in the second information; and in response to the priority information included in the first information and the priority information included in the second information being successfully matched, taking the second information as the successfully matched second information. The mode of matching the quintuple information included in the first information with the quintuple information included in the second information and the mode of matching the priority information included in the first information with the priority information included in the second information are the same as the mode of matching in the first case and the mode of matching in the second case respectively, and are not described herein again. In addition, the priority information included in the first information may be matched with the priority information included in the second information; in response to the fact that the priority information included in the first information is successfully matched with the priority information included in the second information, matching quintuple information included in the first information with quintuple information included in the second information; and in response to the fact that the five-tuple information included in the first information is successfully matched with the five-tuple information included in the second information, taking the second information as the successfully matched second information.

Step 205, the second device adds indication information to the second packet to generate a first packet, where the indication information is used to indicate the type of the first packet.

Exemplarily, the second message is an IP message, the second device adds an indication field in an IP message header of the second message, and the indication field carries indication information; and based on the IP message header added with the indication field, the second equipment generates a first message. Exemplarily, the structure of the IP packet header with the added indication field, the manner in which the indication field carries the indication information, and the manner in which the indication information indicates the type of the first packet are the same as the structure of the IP packet header in step 201, the manner in which the indication field carries the indication information, and the manner in which the indication information indicates the type of the first packet, respectively, and are not described again here.

It should be noted that the second packet may also be other types of packets, and when the second packet is an IP packet, the structure of the header of the IP packet may also be other structures that carry the indication field, which is not limited in this embodiment of the present application.

And step 206, the second equipment sends the first message to the first equipment.

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

In one possible implementation, the method further includes: and the second equipment receives a third message, the type of the third message is different from the types of the messages corresponding to the plurality of pieces of second information in the model library, and the second information corresponding to the type of the third message is added into the model library. Because the type of the third packet is different from the type of the packet corresponding to the second information in the model library, it is indicated that the model library does not have the second information corresponding to the type of the third packet, and therefore, the model library can be more complete by adding the second information corresponding to the type of the third packet to the model library, i.e., the second information in the model library is more comprehensive, and more types can be identified in the subsequent use of the model library.

According to the method provided by the embodiment of the application, the second device generates the first message carrying the indication information for indicating the type of the first message, and then the first message is sent to the first device, the first device can directly determine the type of the first message according to the indication information without comparing other contents of the first message, and the efficiency of determining the type of the first message is high. Secondly, when the type of the first message is the type which needs to perform flow control, the flow control can be performed by adopting corresponding processing modes for different types of messages. According to the scheme of the application, the message is processed in a corresponding mode according to the type of the message, so that the scheme of the application has high flexibility, high flow control accuracy and fine control granularity.
