Therefore, a message transmission method is needed to ensure low network latency while improving throughput, thereby improving user experience.

Detailed ways

The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application and are not intended to limit the present application. In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

This embodiment of the present application provides a message transmission method. Please refer to Figure 1 , which shows a schematic diagram of the implementation environment of the method provided by the embodiment of the present application. The implementation environment includes: a sending device 101 and a receiving device 102. Among them, a first link and a second link are connected between the sending device 101 and the receiving device 102.

Optionally, after receiving multiple messages, the sending device 101 allocates the multiple messages based on the message transmission method provided by the embodiment of the present application, and then transmits the first message to the receiving device 102 through the first link. The second link transmits the second message to the receiving device 102 . Optionally, the sending device 101 and the receiving device 102 are located on the same network device.

Alternatively, the sending device 101 may be a system composed of multiple devices, and the receiving device 102 may be a system composed of multiple devices, which is not limited in the embodiment of the present application.

It should be noted that the network device can be any device that can transmit packets, such as terminals, servers, routers, switches, virtual machines, access switches, access routers (AR), etc.

Based on the implementation environment shown in Figure 1 above, embodiments of the present application provide a message transmission method. The message transmission method can be executed by the sending device. The flow chart of the method is shown in Figure 2, including S201-S202.

S201. The sending device obtains multiple messages to be transmitted. The multiple messages include a first message and a second message. The timing of the first message is earlier than the timing of the second message.

The embodiments of this application do not limit the multiple messages to be transmitted, and they can be messages of any content, type and size. In a possible implementation manner, multiple messages belong to the same service. For example, multiple packets are for the same video phone service. Optionally, multiple messages may also belong to the same type of business, which includes but is not limited to the same business type or the same service level agreement (service level agreement, SLA). For example, the sending device receives multiple video phone service packets. Since the service types of the packets are the same and they are all video phone services, the multiple video phone service packets belong to the same type of service. For another example, the sending device receives a video phone service packet and a game service packet. Since the video phone service and the game service have the same SLA, the video phone service packet and the game service packet belong to the same category. business.

Optionally, the sending device receives multiple messages and uses the multiple messages as messages to be transmitted. The transmission protocol of the multiple received messages may be a transmission control protocol (transmission control protocol, TCP). It may also be other transmission protocols, which are not limited in the embodiments of this application. In addition, the multiple messages received by the sending device may be messages from within the network device. For example, the sending device receives a message forwarded inside the sending device as multiple packets to be transmitted. message. The multiple messages received by the sending device may also be messages from outside the network device, that is, messages sent by other network devices. For example, receive a packet sent from a network device upstream of the sending device. In one possible implementation, the sending device provides a buffer for multiple received messages. After arriving at the sending device, the multiple messages will be cached in the buffer and wait for transmission. For the process of determining the first message and the second message from multiple messages, see S202.

S202, the sending device connects the first link and the second link, and the performance of the first link is better than the performance of the second link; the sending device transmits the first message through the first link, and transmits the second message through the second link. Two messages.

Optionally, the performance of the first link is determined based on at least one of the delay, bandwidth, and packet loss rate of the first link, and the performance of the second link is determined based on the delay, bandwidth, and packet loss rate of the second link. At least one of them is determined. It should be noted that the indicators referenced when determining the performance of the first link and the second link are the same, that is, when the performance of the first link is determined based on the delay of the first link, the second link The performance of the link is determined based on the delay of the second link. Regarding the performance of the first link being better than the performance of the second link, taking the performance of the link based on the delay as an example, when the delay of the first link is lower than the delay of the second link, the first link The performance of the link is better than the performance of the second link. Optionally, the process of obtaining the delay, bandwidth, and packet loss rate of the first link is similar to the process of obtaining the delay of the first link shown in the following embodiments, and the process of obtaining the delay, bandwidth, and packet loss rate of the second link The process of obtaining the packet rate is similar to the process of obtaining the delay of the second link shown in the following embodiments, and will not be described again here.

For example, before transmitting the first message and the second message, the sending device further needs to determine the first message and the second message from multiple messages. The determination method includes: determining the first transmission number of packets transmitted by the first link in one transmission cycle, and determining the second transmission number of packets transmitted by the second link in one transmission cycle; based on the number of multiple messages and The first transmission quantity determines the first message from the plurality of messages, and the second message is determined from the plurality of messages based on the number of the plurality of messages and the second transmission quantity.

Optionally, determining the first transmission number of packets transmitted by the first link in one transmission cycle includes: determining the transmission cycle based on the delay of the first link and the delay of the second link; The first transmission number is calculated based on the average packet size, transmission cycle and bandwidth of the first link. The embodiments of this application do not limit the method of obtaining the delay of the first link and the delay of the second link, and they can be obtained by including but not limited to the following three methods.

Obtaining method 1: The sending device receives the delay of the first link and the second link sent from the receiving device. The delay is obtained based on statistics of the receiving device. The receiving device is connected to the first link and the second link.

For example, Figure 3 provides a schematic diagram of a process of transmitting multiple messages. Referring to Figure 3, there are two links (the first link and the second link) connecting the sending device and the receiving device. The receiving device is configured with the link status statistics function. When the receiving device receives the message transmitted from the sending device Finally, based on the received message information, the delays of the first link and the second link are counted, and the delays of the first link and the second link are sent to the network-aware scheduling model of the sending device. The network-aware scheduling model is used to determine the first message and the second message from multiple messages based on the received delays of the first link and the second link. In one possible case, the received message information includes the time of the received message.

It should be noted that the packets received by the receiving device for counting the delay of the first link and the second link may be packets transmitted by the sending device to meet user requirements before the sending device transmits multiple packets. arts. For example, messages transmitted to meet users' needs for network access. The message received by the receiving device for counting the delay of the first link and the second link may also be a message only used for obtaining the delay of the first link and the second link. For example, the sending device sends a test packet to the receiving device, and the receiving device counts the delays of the first link and the second link based on the test packet, and sends the statistical results to the sending device.

Optionally, the receiving device may periodically collect statistics on the delays of the first link and the second link. The statistical period can be a value with any unit and size set based on experience. For example, set the statistical period to count once for each transmission. At this time, the reception Each time the device receives a message transmitted by the sending device, statistics will be collected. For another example, set the statistics period to once every minute. At this time, the receiving device counts the delay of the first link and the second link every one minute. Optionally, after collecting statistics based on the statistical period, the receiving device may send the statistical results to the sending device every time the statistics are collected, so that the sending device obtains the delays of the first link and the second link. The receiving device can also send statistical results to the sending device based on the sending period after collecting statistics based on the statistical period. The process of determining the sending cycle is similar to the process of determining the statistical cycle, and will not be described in detail here.

Obtaining method 2: The sending device counts the delays of the first link and the second link.

Optionally, the second acquisition method should be used in an application scenario where the sending device is configured with a link status statistics function. For example, sending devices with built-in link status statistics functions include ARs with active link detection and ARs that can perform dialing algorithms or congestion control algorithms. Congestion control algorithms are, for example, bottleneck bandwidth and round-trip propagation time (BBR). Since executing the above congestion control algorithm requires its own link status statistics as input to the congestion control algorithm, that is, the AR that executes the congestion control algorithm is configured with the link status statistics function.

For example, FIG. 4 provides a schematic diagram of another process of transmitting multiple messages. Referring to Figure 4, there are two links (the first link and the second link) connecting the sending device and the receiving device. The sending device is configured with a network-aware scheduling model to determine the first message from multiple messages. and the second message. The sending device obtains the delay of the first link and the second link based on its own link status statistics function. Optionally, the link status statistics function of the sending device can be implemented by a network-aware scheduling model. In this case, the network-aware scheduling model is not only used to determine the first message and the second message from multiple messages, but also The delays of the first link and the second link can be obtained directly. Optionally, the link status statistics function of the sending device may not be a function of the network-aware scheduling model, but may be implemented by an independent link status statistics module. At this time, after obtaining the delay of the first link and the second link, the module with the link status statistics function inside the sending device can send the delay of the first link and the second link to the network-aware scheduling Model.

Obtaining method three: receiving the delay of the first link and the second link sent from the network management device. The network management device is used to manage the network related to the sending device.

Optionally, the network related to the sending device may refer to the network used by the sending device to transmit multiple packets, or may also refer to other networks. The network management device manages the network related to the sending device to ensure the normal and efficient operation of the network. The embodiments of this application do not limit the network management device, and it can be any device embedded with a network management protocol, such as a router, a switch, etc. The network management device counts the delays of the first link and the second link, and sends the delays of the first link and the second link to the sending device.

No matter how the delay of the first link and the second link is obtained, the sending device can determine the transmission period based on the delay of the first link and the second link. For example, the least common multiple (LCM) of the delay of the first link and the delay of the second link is calculated, and the least common multiple is determined to be the transmission period. After the transmission period is determined, the first transmission number may be further calculated based on the average message size of multiple messages, the transmission period and the bandwidth of the first link. The process of obtaining the bandwidth of the first link is similar to the process of obtaining the delay of the first link, and will not be described again here. Optionally, for the situation where the sending device caches multiple received messages in the buffer as shown in the above embodiment, the sending device obtains the average message size of the multiple messages cached in the buffer. Of course, the sending device can also obtain the average packet size of multiple packets based on other methods. For example, the sending device has a packet statistics function and counts the average packet size of multiple packets to be transmitted based on the packet statistics function.

For example, the delay R _i =(R ₁ , R ₂ ,..., R _n ) corresponding to the link _Pi = (P ₁ , P ₂ ,...P _n ), and the bandwidth C _i = (C ₁ , C ₂ ,...,C _n ), the average message size of multiple messages is L, calculate the transmission period K=LCM (R ₁ , R ₂ ,..., R _n ), calculate the transmission period of each link within the transmission period K The number of transmission messages pkt _i = (pkt ₁ , pkt ₂ , ..., pkt _n ), pkt _i = (R _i ×C _i ×K)/L.

Among them, i is the index used to distinguish links, and n is a positive integer. When n equals 2, that is, the sending device shown in the above embodiment connects the first link and the second link. The embodiment of the present application does not limit the link sorting method, which may be based on increasing delay. In this case, link P ₁ is the link with the lowest delay. It can also be sorted in descending order based on transmission delay. In this case, link P ₁ is the link with the highest delay. LCM is used to represent the least common multiple. Taking n as 2 as an example, K=LCM(R ₁ , R ₂ ), that is, K is equal to the least common multiple of R ₁ and R ₂ . Taking the first link as link P ₁ as an example, the relationship between the above-mentioned link, delay, bandwidth and transmission quantity will be explained with an example. The corresponding delay of link P ₁ is R ₁ and the bandwidth of link P ₁ is C ₁ , based on the average packet size L of multiple packets, the first transmission number of link P ₁ within one transmission cycle K is calculated to be pkt ₁ .

Illustratively, taking the schematic diagram of the process of transmitting messages shown in Figure 3 as an example, the performance of the first link is determined based on the delay of the first link, and the performance of the second link is determined based on the delay of the second link. . For example, the delay of the first link is 40 milliseconds (MS) and the bandwidth is 10 megabits per second (Mbps). The delay of the second link is 80ms and the bandwidth is 10Mbps. Multiple reports The average size of a message is 100 bytes (byte, B). Based on the delay of the first link and the delay of the second link, the transmission period is determined to be 80ms. At this time, the first transmission number of the first link is 100, and the second transmission number of the second link is also 100. .

Optionally, the determination process of the second transmission quantity is similar to the determination process of the first transmission quantity, and will not be described again here. After determining the first transmission number and the second transmission number, the first message and the second message may be determined from the plurality of messages based on the first transmission number and the second transmission number. For example, the first message among the plurality of messages whose timing sequence is not greater than the first transmission number is determined as the first message. Among them, the timing of multiple messages is also the time sequence in which the messages arrive at the sending device. After determining the first message from multiple messages, the first message after the end position of the first message can be used as the starting position of the second message, and a number no greater than the second transmission number can be selected. message as the second message.

Taking the first transmission number of the first link calculated in the above embodiment as 100, and the second transmission number of the second link as 100 as an example, at this time, the sum of the first transmission number and the second transmission number is for 200. When the number of multiple messages to be transmitted is 198 (less than 200), the 198 messages are numbered 1-198 according to the timing. The determination method is to determine the message with the timing number 1-100 as the first message. message, and determine the message with timing number 101-198 as the second message. Among them, the message with timing number 1 is the first message to arrive at the sending device, and the message with timing number 2 is the second message to arrive at the sending device. The meaning of other timing numbers is the same as timing number 1 and timing. The meaning of number 2 is similar and will not be repeated here.

In a possible implementation, the sending device groups multiple received messages. For example, the multiple messages are grouped based on the service type, and messages of the same service type are grouped into one group. For example, the sending device receives packets of video phone services and packets of game services with the same SLA. Among them, the timing numbers of the packets of the video phone service are 1-98, and the timing numbers of the packets of the game service are 99-198. The receiving device divides the packets of the video phone service into one group and the packets of the game service into another group based on the service type. At this time, when selecting the first message from multiple messages, in addition to referring to the first transmission number, the grouping situation of the multiple messages is also referenced. For example, select packets with timing numbers 1-98 as the first packet, and select packets with timing numbers 99-198 as the second packet, so that packets in the same group are located on the same link.

Optionally, the grouping of multiple messages can also be grouped based on the generation time of the multiple messages, and the messages whose generation time interval is less than the time threshold are grouped into one group. For example, the sending device receives the packets of a video phone service and divides the packets whose generation time interval is less than the time threshold into one group. The grouping result is that the packets with timing number 1-50 are one group, and the timing number is Messages with sequence numbers 50-98 are one group, messages with sequence numbers 99-125 are one group, and messages with sequence numbers 126-198 are the last group. Determine the message with timing number 1-98 as the first message, and determine the message with timing number 99-198 as the second message. message. Determine the first message from multiple messages based on grouping, ensuring that messages in the same group are on the same link, avoiding intra-group chaos in a group of messages due to different performance of different links. sequence situation. Optionally, the time threshold can be a value of any size and unit set based on experience. The time threshold can also be set based on the implementation environment, which is not limited in the embodiments of the present application.

It should be noted that when determining the first message from multiple messages based on the grouping situation of multiple messages, the first transmission quantity and the second transmission quantity also need to be considered. Before ensuring that the number of first messages does not exceed On the basis that the first transmission quantity and the second transmission quantity do not exceed the second transmission quantity, a group of messages is implemented on one link. Optionally, when ensuring that a group of messages is on one link, there may be a situation where the number of first messages exceeds the first transmission quantity or the number of second messages exceeds the second transmission quantity. At this time, the sending device You can choose to put a group of messages with later timing in the next transmission cycle. For example, messages with timing numbers 1-77 are one group, messages with timing numbers 78-161 are one group, messages with timing numbers 162-198 are one group, and the sending device determines that the timing numbers are 1-77 The message with sequence number 78-161 is regarded as the first message, the message with sequence number 78-161 is determined as the second message, and the message with sequence number 162-198 is the remaining message.

In addition, when determining the first message and the second message from multiple messages, there is also a situation where the number of multiple messages is not greater than the first transmission number, that is, the first link can Transmit a plurality of first messages to the receiving device. When the performance of the first link is much better than that of the second link, there is no need to distribute multiple packets to the second link. For example, the first transmission number of the first link is 100, and the second transmission number of the second link is also 100. When the number of multiple messages to be transmitted is less than 100, the sending device can further compare the number of packets to be transmitted. The performance of one link versus the performance of the second link. Optionally, the performance of the first link is much better than that of the second link means that the difference between the indicator used to determine the performance of the first link and the indicator used to determine the performance of the second link is greater than the scheduling threshold . As an example, take the indicator used to determine the performance of the first link as delay, the scheduling threshold as 30 ms, the delay of the first link as 40 ms, and the delay of the second link as 80 ms. Since the difference between the delay of the first link and the delay of the second link is 40ms, which is greater than the scheduling threshold, that is, the performance of the first link is much better than that of the second link. At this time, multiple The message is determined to be the first message, and multiple messages that do not exceed its own load capacity are transmitted through the first link. On the basis of ensuring the normal transmission of multiple messages, low-latency transmission of multiple messages is achieved. . Alternatively, the scheduling threshold may be set based on experience, with units consistent with the metric used to determine the performance of the first link.

After the first message and the second message are determined, the first message is transmitted through the first link, and the second message is transmitted through the second link. Taking the above embodiment as an example of determining that the message with sequence number 1-100 is the first message and the message with sequence number 101-198 as the second message, based on the first link transmission sequence number is 1 The first message of -100 is based on the second message with transmission sequence number 101-198 on the second link. By allocating packets according to the timing of multiple packets, the second packet with later timing is allocated to the second link with lower performance for early transmission, because the second packet with later timing does not need to wait for the second packet with earlier timing. As soon as the message transmission is completed, the transmission can be started, which shortens the transmission time. In addition, by allocating the first message to the first link with excellent performance, it can arrive at the sending device first, thereby achieving approximately orderly arrival of multiple messages at the receiving device.

It should be noted that, in addition to the grouping situation based on multiple messages shown in the above embodiment, there will be remaining situations after determining the first message and the second message from multiple messages. When the number of multiple messages is greater than the When the sum of the first transmission quantity and the second transmission quantity is equal to the sum of the first transmission quantity and the second transmission quantity, remaining messages will also appear. For example, the number of multiple messages is greater than the sum of the first transmission number and the second transmission number, that is, the sending device cannot send all the multiple messages to the receiving device in one transmission cycle. At this time, the sending device determines the first message and the second message from the multiple messages. The determination method may refer to the method of determining the first message and the second message shown in the above embodiment. The method of obtaining the number of multiple messages is similar to the method of obtaining the average message size of multiple messages, and there is no difference here. To elaborate further.

Taking the first transmission number calculated in the above embodiment as 100 and the second transmission number also as 100 as an example, at this time The sum of the first transmission number and the second transmission number is 200. When the number of multiple messages to be transmitted is 300 (more than 200), the sequence number is 1-300. The determination method is to determine the messages with timing numbers 1-100 as the first message, and determine the messages with timing numbers 101-200 as the second message. The first message is transmitted through the first link, and the second message is transmitted through the second link. For the remaining packets in the plurality of packets except the first packet and the second packet, for example, the packets with sequence numbers 201-300, the processing method can be referred to the following embodiments.

In a possible implementation, for the situation where there are remaining messages in multiple messages, after sending the first message and the second message, the sending device will also contact the first link based on the number of remaining messages. Based on the corresponding transmission number and the corresponding transmission number of the second link, the fourth message and the fifth message are determined from the remaining messages. The timing of the fourth message precedes the timing of the fifth message. The fourth message is transmitted through the first link, and the fifth message is transmitted through the second link. Optionally, the process by which the sending device determines the fourth message and the fifth message from the remaining messages is similar to the process by which the sending device determines the first message and the second message from multiple messages, where No more details will be given. In addition, since the packets to be transmitted have changed from multiple packets to the remaining packets among the multiple packets, the sending device will re-obtain the average packet size of the remaining packets, based on the remaining packets. The average packet size is calculated as the number of transmissions between the first link and the second link in one transmission cycle.

It should be noted that when the sending device sends the first message and the second message to the receiving device, the sending device may also receive other messages to be transmitted. When sending the remaining messages, the sending device may first allocate the remaining messages based on the above embodiment, and then allocate other messages after the remaining messages are transmitted. The sending device can also allocate the remaining messages and other messages to the first link and the second link based on the average message size and number of messages of the remaining messages and other messages based on the method shown in the above embodiment. The application examples do not limit this.

Optionally, after receiving the first message and the second message transmitted by the sending device, the receiving device will obtain the target message based on the first message and the second message, check the order of the target messages, and adjust the target The out-of-order portion of the message. Taking the message with the sequence number 1-100 as the first message and the message with the sequence number 101-198 as the second message as an example, the receiving device receives the first message with the sequence number 90 based on the first link. message, the second message with sequence number 101 from the second link is received. At this time, the acquired target packets are partially out of order, and the receiving device will rearrange the out-of-order parts of the target packets and send the rearranged target packets to the destination. Optionally, the destination is the local area network (LAN) side, and the rearrangement is implemented using the rearrangement cache that comes with the TCP protocol. It should be noted that the first message sent based on the first link and the second message sent based on the second link are both determined based on the timing sequence. Therefore, the out-of-sequence part of the target packet is also limited to the tail of the transmission queue of the first link and the head of the transmission queue of the second link. The workload of rearrangement is small and the time is short.

For example, after sending multiple target packets, the receiving device will also calculate the latest delays of the first link and the second link based on the status of the received target packets, and compare the first link and the second link. The latest delay of the second link is sent to the network-aware scheduling model of the sending device to update and calibrate the delays of the first link and the second link. The sending device that receives the latest delay of the first link and the second link may be a sending device with a link statistics function, or may be a sending device without a link statistics function. This is not the case in the embodiment of the present application. Make restrictions.

It should be noted that the above example is intended to illustrate the message transmission process of multiple links, but does not limit the number of links connected between the sending device and the receiving device. Two links can be connected between the sending device and the receiving device, or more than two links can be connected. Among the two or more links, there are at least two links with different performance. In addition, when more than two links are connected between the sending device and the receiving device, the sending device can select two links from the two or more links to perform the message transmission method provided by the embodiment of the present application, and the sending device can also Select two or more links from the two or more links to perform the message transmission method provided by the embodiment of the present application.

Optionally, the sending device is also connected to a third link, when the performance of the first link and the second link is better than the performance of the third link. When enabled, the sending device obtains the third message to be transmitted, the timing of the first message and the second message is earlier than the timing of the third message, and transmits the third message through the third link. The method of transmitting the third message based on the third link is similar to the method of transmitting the first message based on the first link shown in the above embodiment, and will not be described again here. The performance of the third link may be different from the performance of the first link and the performance of the second link as shown in the above embodiment. The performance of the third link may also be the same as the performance of the first link, or may be different from the performance of the first link. The performance of the second link is the same. The method of determining the performance of the third link is similar to the method of determining the performance of the first link, and will not be described in detail here. Regarding the same performance, that is, the indicators used to determine performance are the same. Taking determining performance based on delay as an example, the performance of the third link is the same as the performance of the first link, which means that the delay of the third link is the same as that of the first link. The delay of the first link is the same.

To sum up, in the message transmission method provided by the embodiment of the present application, since the first message is the message with earlier timing among multiple messages, the first message with earlier timing is transmitted through the first link with better performance. Messages effectively alleviate the message out-of-order situation caused by the mismatch between link performance and timing. This message transmission method not only improves throughput, but also achieves low-latency transmission.

In addition, the indicators used to allocate the first packet and the second packet (the first transmission quantity and the second transmission quantity) are determined based on the delay and bandwidth of each link and the average size of multiple packets to be transmitted. , that is, the indicators used to allocate the first packet and the second packet will be flexibly adjusted based on the conditions of the packets to be transmitted, so the method of allocating the first packet and the second packet is more flexible.

Since the first message of the above device is the message with the earlier timing among multiple messages, the first message with the earlier timing is transmitted through the first link with better performance, which effectively alleviates the situation of packet disorder.
