Detailed Description

The terminology used in the description of the embodiments of the application herein is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application. For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

In equal cost multi-path (ECMP), multiple links may be connected between two transmission devices, and the transmission devices may use the multiple links to share the transmission of the message in the process of transmitting the message, so as to increase the transmission bandwidth and improve the transmission efficiency. The transmitted message comprises a first message and a second message, and the transmission requirement of the first message is higher than that of the second message. The multiple links connected between the two transmission devices all meet the transmission requirement of the second message, and can transmit the second message, but only part of the links meet the transmission requirement of the first message, so how to transmit the message becomes a problem to be solved.

In the related art, since the multiple links can meet the transmission requirement of the second message, the multiple links share the transmission of the second message in an equally-divided manner. The transmission mode can lead to the fact that the links capable of transmitting the first messages transmit too many second messages, the links capable of transmitting the first messages are occupied too much, and the transmission of the first messages cannot be guaranteed and is easy to influence. Based on the above, the embodiment of the application provides a message transmission method.

Fig. 1 is a schematic diagram illustrating an implementation environment of a message transmission method according to an embodiment of the present application. The implementation environment includes a plurality of transmission devices. And a plurality of links, namely a first link and a second link, are connected between any two transmission devices in the plurality of transmission devices. The link connection in fig. 1 is intended to illustrate a connection relationship between transmission devices, and is not used to define a connection manner of the transmission devices, and the link connected between the transmission devices may be established by a wired or wireless network, that is, the link connection in fig. 1 is not used to define an actual physical connection between the transmission devices. In addition, the number of transmission apparatuses included in the network topology may be 8 transmission apparatuses of the transmission apparatus 1 to the transmission apparatus 8 shown in fig. 1, or may be other numbers. Moreover, the number of links connected between different transmission devices may be the same as shown in fig. 1 or may be different.

The embodiment of the application is not limited to the network device for executing the message transmission method, and the network device may be a transmission device configured on a forwarding path. Taking the first link through which the message is transmitted as an example of the first link between the transmission device 1 and the transmission device 2 in fig. 1, the network device is the transmission device 1 or the transmission device 2. Alternatively, the network device may be connected to the transmission device instead of being arranged on the forwarding path. For example, as shown in fig. 2, the control device 01 and the transmission device establish a communication connection by way of a wired or wireless network, and the control device 01 can interact with the transmission device to implement management of a link connected with the transmission device. The transmission devices to which the control device 01 is connected may be part of the transmission devices shown in fig. 2, for example, the transmission device 1, the transmission device 2, and the transmission device 4, or may be all the transmission devices in the network topology.

In addition, the control device 01 and the transmission device may independently execute the message transmission method provided by the embodiment of the present application, or may interactively execute the message transmission method provided by the embodiment of the present application. For example, after determining the bandwidth demand of the first link, the control device 01 issues the bandwidth demand of the first link to the transmission device, and the transmission device determines the transmission weight of the first link according to the received bandwidth demand, and transmits the second message through the first link according to the transmission weight.

Alternatively, the transmission device in fig. 1 and 2 may be a Router (RT), or may be other devices with packet forwarding capability, such as a switch and Gateway (GW), etc. The control device 01 in fig. 2 may be any device having data processing capabilities, and may be a server, for example a central server, an edge server, or a local server in a local data center. The server can be a physical server, and can also be a cloud server for providing cloud computing service in a cloud scene. In some embodiments, the control device 01 may also be a terminal device such as a desktop, notebook, or smart phone.

The flow chart of the message transmission method provided by the embodiment of the application is shown in fig. 3, and comprises S301-S303.

S301, obtaining the bandwidth demand of a first link, wherein the first link meets the transmission demands of a first message and a second message, the bandwidth demand is the bandwidth of the first link for transmitting the first message, and the transmission demand of the first message is higher than the transmission demand of the second message.

Illustratively, the first link refers to a link with high transmission performance. The transmission performance of the link can be determined according to transmission parameters such as time delay, bandwidth, packet loss rate and the like. For example, when the time required for end-to-end transmission through one link is less than 20 milliseconds, it is determined that the transmission performance of the link is high, belonging to the first link. When the bandwidth of one link is higher than 40 gigabytes (G), it is determined that the transmission performance of the link is high, belonging to the first link. Or when the packet loss rate of one link is lower than 0.5%, determining that the transmission performance of the link is high, and belonging to the first link.

Based on high transmission performance, the first link can meet the transmission requirements of the first message and the second message. The first message and the second message may be any type of message, including but not limited to a game message, a video message, a picture message, and the like. The message types of the first message and the second message may be the same or different. The transmission requirement of the first message is higher than that of the second message. The transmission requirement of the message can be determined according to a service level agreement (SERVICE LEVEL AGREEMENT, SLA) of the message, and when the transmission delay specified in the SLA of a certain message is smaller than a first threshold value, the transmission requirement of the message is determined to be high, and the message belongs to the first message. Otherwise, determining that the transmission requirement of the message is low, and the message belongs to the second message.

Because the link in the network capable of meeting the transmission requirement of the first message is the first link, that is, the link carrying the first message is the first link. For example, as shown in fig. 4, the first links connecting between different transmission devices may be considered as being integrated in a single network plane, which is used for carrying the transmission of the first message. When the transmission requirement of the first message exists, path calculation is directly carried out according to the integrated network plane, and a transmission path formed by a first link with high transmission performance is planned on the network plane. And because the first message has high requirements for network quality assurance and low transmission fault tolerance, even if the first link can meet the transmission requirement of the second message, the transmission of the second message is carried out, and the transmission of the first message is also required to be guaranteed preferentially. Based on the priority guarantee requirement, the network device for executing the message transmission method obtains the bandwidth requirement of the first link, where the bandwidth requirement is the bandwidth of the first link for transmitting the first message.

The embodiment of the application does not limit the time for the network equipment to acquire the bandwidth demand of the first link, and can be after receiving the demand of transmitting the second message. For example, the network device acquires a transmission path of a second message to be transmitted, and counts a bandwidth demand of a first link corresponding to the transmission path of the second message. The first link corresponding to the transmission path refers to a first link connected between transmission devices included in the transmission path. As shown in fig. 5, the transmission path of the second packet is transmission device 1-transmission device 2-transmission device 3-transmission device 4, and the first links corresponding to the transmission path are the first link 1 connected between the transmission device 1 and the transmission device 2, the first link 2 connected between the transmission device 2 and the transmission device 3, and the first link 3 connected between the transmission device 3 and the transmission device 4, respectively. The network device executes the message transmission method provided by the embodiment of the application and starts to determine the bandwidth demand of the first link corresponding to the transmission path.

Alternatively, the network device may determine the bandwidth requirements of each first link managed before receiving the requirement for transmitting the second message. For example, as shown in fig. 6, link a in fig. 6 is a first link, and the network device obtains a bandwidth requirement of 5 gigabytes (G) of the first link. And determining the transmission weight of each first link according to the bandwidth demand of the first link so as to directly transmit the second message according to the transmission weight of the first link under the condition that the second message needs to be transmitted, thereby improving the transmission efficiency of the second message.

In one possible scenario, the bandwidth requirement of the first link indicates a bandwidth size reserved for the first message in the first link, which reserved bandwidth size may be a fixed value set empirically. Taking a flexible algorithm (flex-algorithm, flex-algo) as an example, the first link belongs to a link used for transmitting a message of flex-algo in a circuit topology defined by the flex-algo algorithm. In the road calculation scene, the first message is a message of flex-algo. Empirically, a bandwidth of 2 gigabytes (G) exists in the first link for a packet of fixed transmission flex-algo, then the bandwidth requirement of the first link is 2G.

In another possible scenario, the bandwidth size reserved for the first link may also be determined according to the message prediction result. The network equipment determines the corresponding relation between the historical flow of the first message and the transmission moment according to the historical transmission condition of the first message; determining the flow of the first message according to the corresponding relation between the current moment and the historical flow and the transmission moment of the first message; and determining the bandwidth demand according to the flow size of the first message. Taking 9-day as an operation peak period of an entertainment application program, taking a service corresponding to a first message as an example of the entertainment application program, determining that a first message can generate a flow burst at 9-day according to a historical transmission condition of the first message, predicting that the flow of the first message at 9-day is likely to be 100 gigabytes (G), determining that a first link needs to reserve 90% of bandwidth for transmitting the first message according to the predicted flow of the first message, and determining that the bandwidth demand of the first link is 90% multiplied by the total bandwidth of 10G=9G.

The bandwidth requirement of the first message may also be determined based on the bandwidth currently used by the first link to transmit the first message. Since the different network devices acquire the bandwidths used by the first link to transmit the first message currently, the acquisition modes of the control device in the two cases will be described respectively.

In the first acquisition mode, when the network device is a transmission device connected with the first link, the transmission device determines the bandwidth demand according to the bandwidth used by the first link to transmit the first message when the link identifier included in the first message is the first link.

In one possible implementation manner, after receiving the message to be transmitted, the transmitting device needs to determine whether the message to be transmitted is the first message, and then determine the bandwidth demand according to the bandwidth used by the first link to transmit the first message if the message to be transmitted is the first message. The process of determining whether the message to be transmitted is the first message is, for example, that the transmitting device parses the message to be transmitted, and determines whether the message to be transmitted is the first message according to fields that can identify service information, such as DIFFERENTIATED SERVICES code-point (DSCP), flow label (flow label), five-tuple, and the like, included in the message to be transmitted.

Fig. 7 and 8 show fields carrying identifiable service information in a message to be transmitted, and fig. 7 shows a message to be transmitted belonging to internet protocol 4 th edition (internet protocol version, ipv 4), where the message to be transmitted includes a version (version) field, a header length (HEAD LENGTH) field, a type of service (ToS) field, a total length of data (total length) field, and the like. The ToS field includes a DSCP field byte, and bits 0 to 5, which are the lower 6 bits in the DSCP field byte, are used to distinguish service code points DSCP. Bits 0-2, which are the lower 3 bits, are class selection code points (class selector code point, CSCP), representing a class of DSCP used to identify traffic information. Bits 6 and 7, which are the upper 2 bits, are reserved bits.

Fig. 8 shows a message to be transmitted belonging to IPv6, where the message to be transmitted includes a version (version) field, a traffic class (TRAFFIC CLASS, TC) field, a Flow Label (FL) field, and a payload length (payload length) field. There are two fields related to quality of service (quality of service, qoS) that can be used to identify the traffic information of the message to be transmitted, the TC field and the FL field, respectively. The TC field has 8 bits, has the same function as the ToS field of the message to be transmitted, which belongs to IPv4 and is shown in fig. 7, and is used for identifying the service information of the message to be transmitted; the FL field has 20 bits for identifying messages for the same service. The FL field, together with the source address and destination address, uniquely identifies a service message. According to the TC field and the FL field, after determining the service information of the message to be transmitted, the transmission device determines that the message to be transmitted is the first message under the condition that the service information is the service information corresponding to the first message.

After determining that the received message to be transmitted is the first message, the transmission device further determines a first link to which the first message needs to be transmitted. For example, one transmission device may be connected to a plurality of first links. Taking the transmission device 1 shown in fig. 5 as an example, a first link is connected between the transmission device 1 and the transmission device 2, and a first link is also connected between the transmission device 1 and the transmission device 5. Therefore, after receiving the first message to be transmitted, the transmission device 1 analyzes the received first message, and obtains the link identifier carried in the first message to determine the transmission link of the first message. The link identification may be a device identification of a next hop device of the first message, an address of a next hop device. The transmission device determines the next hop device to be sent to according to the link identification, so as to determine a first link for transmitting the first message, and statistics the bandwidth used by the first link for transmitting the first message. The statistics process is, for example, that since the first messages of the same service have the same FL field, the traffic of the first message can be counted according to the FL field, so as to determine the bandwidth used by the first link for transmitting the first message.

Taking the Slice service scenario as an example, the link identifier of the first message is a Slice identity number (SLICE IDENTITY documents, slice ID). Such as the message structure of the first message shown in fig. 9, which includes an internet protocol version 6 (internet protocol version, IPv 6) message header, a hop-by-hop header (hop-by-hop header), a segment routing header (segment routing header, SRH) and an IPv6 payload. The hop-by-hop header includes a plurality of fields as shown in fig. 9, and the plurality of fields include a Slice ID field. And because the interfaces of different first links on the transmission equipment are different, the transmission equipment searches FlexE interfaces of the corresponding slicing resources of the next-hop equipment according to the Slice ID field, and the determination of the transmission link of the first message is completed. When the determined transmission link is the first link which is currently counting the bandwidth demand, the transmission equipment can count the flow of the first message carrying the Slice ID in real time according to the Slice ID field, so that the bandwidth used by the first link for transmitting the first message carrying the Slice ID is obtained.

The bandwidth requirement can be determined according to the bandwidth used by the first link to transmit the first message no matter what mode the transmission device determines the bandwidth of the first link to transmit the first message. Optionally, the transmission device uses the bandwidth used by the first link to transmit the first message as the bandwidth requirement. For example, if the bandwidth used for transmitting the first message by the first link is 2G, the bandwidth requirement of the first link is 2G. Or the transmission equipment combines the reserved bandwidth on the basis of the bandwidth used by the first link for transmitting the first message, and determines the bandwidth demand. Continuing taking the bandwidth used by the first link to transmit the first message as 2G as an example, setting the reserved bandwidth of the first link to be 1G based on experience, and then setting the bandwidth requirement of the first link to be 2+1=3 gigabytes (G). By setting the reserved bandwidth, the transmission bandwidth is reserved for the first message to be transmitted later on the basis of the occupied bandwidth of the first message, so that the normal transmission of the first message to be transmitted later is ensured.

And in the second acquisition mode, under the condition that the network equipment is control equipment connected with the transmission equipment, receiving the bandwidth used by the first link transmitted by the transmission equipment for transmitting the first message, and determining the bandwidth demand according to the bandwidth used by the first link for transmitting the first message.

In one possible case, the control device is configured to perform calculation of the transmission path according to the operation condition of each link to which the transmission device is connected. Therefore, the transmission device can report the bandwidth usage of each connected link including the first link to the control device in real time, and the control device obtains the operation condition of each link according to the received bandwidth usage of each link. The process of the transmission device counting the bandwidth used by the first link to transmit the first message is similar to the process of the transmission device counting the bandwidth used by the first link to transmit the first message in the first acquisition mode, and reference may be made to the related description, which is not repeated here.

The control device may also determine, for example, a bandwidth used by the first link to transmit the first message according to a result of the routing of the first message. According to the source port and the destination port of the first message, the control device calculates a first link which the first message needs to pass through by a route, and determines the bandwidth used by the first link which needs to pass through according to the route calculation result. For example, the control device calculates an end-to-end segment routing IPv 6Policy (segment routing IPv Policy, SRv Policy) path for the first packet a on the network plane of the first link integration as a transmission device 1-transmission device 2-transmission device 3-transmission device 4, and determines that the first link between the transmission devices corresponding to the first packet a is occupied by 5G bandwidth according to the path calculation result. The control device may then determine the bandwidth requirement according to the bandwidth used by the first link to transmit the first message, and optionally, the process of determining the bandwidth requirement according to the bandwidth used by the first link to transmit the first message by the control device is similar to the process of determining the bandwidth requirement according to the bandwidth used by the first link by the transmission device in the first acquisition mode, which will be described with reference to the related description and will not be repeated here.

S302, determining a transmission weight corresponding to the first link according to the bandwidth demand, wherein the transmission weight indicates the flow size of the second message to be transmitted when the first link meets the bandwidth demand.

Optionally, the process of determining the transmission weight by the network device includes: acquiring the total bandwidth of a second link, wherein the second link and the first link are links between transmission equipment for transmitting a first message and a second message, and the second link meets the transmission requirement of the second message and does not meet the transmission requirement of the first message; and determining the transmission weight according to the total bandwidth and the bandwidth demand of the second link.

Referring to fig. 5, the two transmission devices are further connected to a second link on the basis of the connection of the first link, and the transmission performance of the second link is lower than that of the first link. Similar to the determination process of the transmission performance of the first link, the transmission performance of the second link may also be determined according to transmission parameters such as delay, bandwidth, packet loss rate, and the like. When the time required for realizing the end-to-end transmission through one link is not less than 20 milliseconds, the transmission performance of the link is determined to be low, and the link belongs to a second link. When the bandwidth of one link is not higher than 40G, the transmission performance of the link is determined to be low, and the link belongs to a second link. Or when the packet loss rate of one link is not lower than 0.5%, determining that the transmission performance of the link is high, and belonging to the second link.

Based on the low transmission performance, the second link can only meet the transmission requirement of the second message and is responsible for message transmission of the second link. The network device obtains a total amount of bandwidth of the second link. Since the total bandwidth of the second link belongs to the configuration information of the second link, the total bandwidth in the configuration information of the second link is set and stored in the storage space during the process of establishing the second link. The network device may obtain the configuration information of the second link by accessing the storage space, to obtain the total bandwidth of the second link.

Illustratively, after the network device obtains the total bandwidth of the second link, the network device may determine the transmission weight according to the total bandwidth of the second link and the bandwidth requirement of the first link, where the determining process includes: determining the residual bandwidth of the first link according to the bandwidth demand; adding the residual bandwidth of the first link and the total bandwidth of the second link, and obtaining a bandwidth sum according to the adding result; and determining the transmission weight according to the ratio of the residual bandwidth to the bandwidth sum of the first link.

In one possible implementation, the network device obtains a total amount of bandwidth of the first link, subtracts the bandwidth demand from the total amount of bandwidth of the first link, and uses the resultant difference as the remaining bandwidth of the first link. The process of obtaining the total bandwidth of the first link is similar to the process of obtaining the total bandwidth of the second link, and reference is made to the related description, which is not repeated here. Taking the total bandwidth of the first link as 10G and the bandwidth demand as 3G as an example, the determined residual bandwidth of the first link is 10-3=7g.

The remaining bandwidth over the first link indicates a bandwidth size by which the first link can transmit the second message. Alternatively, the network device may choose to determine the remaining bandwidth based on the bandwidth demand, or may choose to directly determine the remaining bandwidth of the first link. The bandwidth size for transmitting the second message in the first link is determined empirically, resulting in a remaining bandwidth of the first link. For example, the existence of 5G bandwidth in the first link is specified based on experience for fixed transmission of the second message, thereby directly determining that the remaining bandwidth of the first link is 5G.

Regardless of the manner in which the network device obtains the remaining bandwidth of the first link, the remaining bandwidth of the first link and the total amount of bandwidth of the second link may be added to obtain a bandwidth sum. The bandwidth and the overall transmission capacity of the transmission device for transmitting the second message are reflected. The network device then divides the remaining bandwidth by the sum of bandwidths, and takes the divided ratio as a transmission weight. Continuing taking the remaining bandwidth of the first link as 7G as an example, the total bandwidth of the two second links connected by the transmission device 1 in fig. 5 is 10G, and the sum of bandwidths is 7+10+10=27G, and the calculated transmission weight is 7/27.

And determining the transmission weight according to the residual bandwidth of the first link, and reasonably distributing the flow carried by the first link in the second message transmission process according to the transmission capacity of the first link so as to avoid abusing and wasting the transmission capacity of the first link caused by excessively using the high-performance first link to transmit the second message with low transmission requirement, so that the task distribution of the first link and the second link is more reasonable. Further, the transmission weight of the first link may be a value that is continuously changed with the bandwidth demand of the first link. That is, in one possible scenario, the network device may update the transmission weight of the first link according to the change of the bandwidth used by the first link.

The process of updating the transmission weight of the first link may be similar to the process of determining the transmission weight in the above embodiment, and may be determined according to the bandwidth used for transmitting the first packet. For example, the first link further transmits the first packet B on the basis of transmitting the first packet a using the 2G bandwidth, and the bandwidth occupied by the first packet B is 5G, so that the bandwidth change condition used by the first link is changed to 2+5=7g, and the network device updates the bandwidth requirement of the first link to 7G. The remaining bandwidth of the first link is 3G, and the transmission weight is determined to be 3/(3+10+10) =3/23.

In another possible case, the transmission weight of the first link may be determined to be 0 based on the change in the bandwidth used by the first link satisfying the condition for limiting transmission. Wherein the condition that the change condition of the bandwidth used by the first link satisfies the transmission restriction may be that the remaining amount of the bandwidth of the first link is smaller than an empirically set bandwidth threshold. The fact that the bandwidth remaining amount of the first link is smaller than the bandwidth threshold value indicates that the amount of messages which can be transmitted by the first link is smaller, and if the first link is used for transmitting the second message, the first link cannot transmit the first message in time when the first message needs to be transmitted. Therefore, the transmission weight of the first link is set to be 0, so that the first link does not need to bear the message transmission of the second message, and the limited bandwidth is used for guaranteeing the message transmission of the first message.

Alternatively, the first link satisfying the limited transmission condition may further be that the transmission level of the first message currently transmitted by the first link is higher than a reference level set based on experience. The transmission level can be determined according to SLA and the like, and the first link stops transmitting the second message due to the fact that the transmission level of the first message to be transmitted by the first link is high and the tolerance of faults in the transmission process is low, so that smooth execution of the first message transmission is guaranteed.

S303, transmitting the second message through the first link according to the transmission weight.

The network device determines the transmission weight according to any mode, and controls the first link to transmit the second message according to the transmission weight. The proportion of the flow of the second message transmitted by the first link in the total amount of the second message is the same as the transmission weight. The network device may be a transmission device or a control device independent of the transmission device, and the processes of transmitting the second message by the network device through the first link under different conditions are different, and then the processes of controlling the message transmission by the network device under different conditions are respectively illustrated.

In the first transmission mode, when the network device is the control device, the network device sends the transmission weight to the transmission device connected with the first link, and the transmission device is used for transmitting the second message according to the transmission weight through the first link.

Optionally, a communication connection is established between the control device and the transmission device, based on the communication connection, the control device may send transmission information including transmission weights to the transmission device, and after the transmission device receives the transmission information, the transmission device reads the transmission weights in the transmission information, and groups the received second message according to the transmission weights, so as to obtain the first packet. Taking 27G as a second message to be transmitted and 7/27 as an example, the flow size of the second message included in the first packet is 7G. After the transmission equipment finishes grouping, the transmission equipment sends a second message included in the first grouping to the transmission equipment of the opposite terminal through the first link, and the second message is transmitted according to the transmission weight. For example, as shown in fig. 5, the bold straight line is the second message included in the first packet.

And in the second transmission mode, under the condition that the network equipment is the transmission equipment, the transmission equipment carries out grouping on the received second message according to the transmission weight to obtain a first grouping, and the first grouping is transmitted through a first link.

The transmission device, after calculating the transmission weight, groups the second packet according to the transmission weight to obtain the first packet. The process of the transmission device grouping the second message is similar to the process of the transmission device grouping the second message in the first transmission mode, the process of the transmission device transmitting the first packet through the first link is similar to the process of the transmission device transmitting the first packet through the first link in the first transmission mode, and reference is made to the related description, and the description is omitted here.

In one possible case, the network device may further determine a reference weight corresponding to the second link according to a ratio of the total bandwidth and the sum bandwidth of the second link; and transmitting a second message according to the reference weight through a second link. The second link cannot bear the transmission of the first message and is only used for transmitting the second message. Therefore, the reference weight of the second link can be determined according to the total bandwidth of the second link without considering the transmission bandwidth of the first message in the second link. And dividing the total bandwidth of the second link by the sum of the bandwidths, and taking the ratio obtained by the division as a reference weight. Continuing to take the second link shown in fig. 5 as an example, the total bandwidth of the two second links connected to the transmission device 1 is 10G, and the sum of the bandwidths is 27G calculated in the foregoing embodiment, so that the reference weights of the two second links connected to the transmission device 1 are 10/27.

Optionally, the process of transmitting the second message through the second link according to the reference weight is similar to the process of transmitting the second message through the first link according to the transmission weight in the above embodiment, and the network device may group the second message according to the reference weight to obtain a second packet, and transmit the second message included in the second packet through the second link. Continuing to take the total message amount of the second message to be transmitted as 27G as an example, the two second links respectively transmit the messages of 27×10/27=10g. The process of the network device transmitting the second message over the second link is similar to the process of transmitting the second message over the first link, for example, the bolded curve in fig. 5 is the second message included in the second packet transmitted by the second link.

Furthermore, the first link and the second link in the embodiments of the present application are intended to distinguish links with different transmission performance, and are not intended to limit the number of links connected between two transmission devices. For example, the first link connected between two transmission devices may be one or more of fig. 6, and the second link connected may be two or more of fig. 6. The transmission weight may be expressed as a fraction in the above embodiment or may be expressed as other expression. Taking the remaining bandwidth of the first link as 8G and the total bandwidth of the two second links as 10G as an example, the transmission weight of the first link may be further expressed as 8:10:10. taking the remaining bandwidth of the first link as 7G and the total bandwidth of the two second links as 10G as an example, the transmission weight of the first link may be further expressed as 7:10:10.

In addition, since the process of controlling the different first links and second links to transmit the second message is similar, in the process of introducing the message transmission method, the embodiment of the application is temporarily described by taking the first link and the second link connected by one of the transmission devices on the transmission path of the second message as an example. The method is not used for limiting the number of transmission devices to which the message transmission method provided by the embodiment of the application is applicable. For example, as shown in fig. 6, where link a represents a first link, link B and link C represent second links, the bandwidth requirement of each first link and the total bandwidth of each second link may be determined according to the method provided by the embodiment of the present application, so as to obtain the weight corresponding to each link in the network topology map.

In summary, according to the message transmission method provided by the embodiment of the application, the transmission weight corresponding to the first link is flexibly adjusted according to the bandwidth demand of the first link, so that the flow size of the second message transmitted by the first link is defined according to the transmission weight, the bandwidth occupied by the second message on the first link is reduced, the second message is transmitted by reasonably utilizing the first link under the condition that the transmission task of the first message is satisfied, the abuse of the first link is avoided, and the transmission process of the second message is more accurate. And after the transmission weight is determined, the transmission weight of the first link is updated in time according to the change condition of the bandwidth used by the first link, so that the real-time performance is good, and the accuracy of the transmission weight is high.

The device flexibly adjusts the transmission weight corresponding to the first link according to the bandwidth demand of the first link, and definitely transmits the flow of the second message according to the transmission weight, so that the bandwidth required by the first message transmitted in the first link is deducted in the process of determining the flow of the second message, the occupied bandwidth of the second message in the first link is reduced, the second message is transmitted by reasonably utilizing the first link under the condition of meeting the transmission task of the first message, the message transmission process is more accurate, and the reliable transmission of the first message is ensured.
