As shown in fig. 1, the computer terminal may include one or more (only one is shown in fig. 1) processors 102 (the processor 102 may include, but is not limited to, a microprocessor MCU or a processing device such as a programmable logic device FPGA) and a memory 104 for storing data, wherein the computer terminal may further include a transmission device 106 for communication functions and an input-output device 108.

In one example, the transmission device 106 includes a network adapter (Network Interface Controller, simply referred to as NIC) that can connect to other network devices through a base station to communicate with the internet. In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is configured to communicate with the internet wirelessly.
In this embodiment, a network transmission method running on the computer terminal is provided, and fig. 2 is a flowchart according to an embodiment of the present application, as shown in fig. 2, where the flowchart includes the following steps:
step S202, receiving a target message sent by a source server, and determining a multi-item-destination transmission path of the target message through a target server address corresponding to the target message, wherein the target transmission path represents a transmission path of the target message from a relay server to a target server;
step S204, determining the priority of a multi-label transmission path;
step S206, determining the transmission strategy of the target message according to the priority of the multi-label transmission path, the bandwidth required by the target message transmission and the residual bandwidth of the multi-label transmission path.
In the network transmission process, the relay server receives the target message sent by the source server, and the relay server passes through the transceiver device in the target transmission path, for example: the switch forwards to the target server.
In step S204, the priority of the multi-label transmission path, in an alternative manner, to a network segment of an entry, for example: in the case of a target server with multiple static routes, the conventional static path selection scheme:
1. the static route to an entry can be set with its priority and label value, the priority typically being the preferred criterion for static route. The configuration of the priority is generally based on the link bandwidth and the hop count to the destination network segment;
2. routes of the same priority as the plurality of static routes to the destination network segment, referred to as equivalent routes, the equivalent routes evenly distributing bandwidth to the destination network segment;
3. when the priorities of the static routes to the destination network segment are different, called non-equivalent routes, a route with a high priority is selected in the related art, and a route with a low priority is activated only in the case that the route with the high priority fails.
It can be understood that the priority configuration parameter of the static route is considered in the conventional static route selection scheme, and in the case of the configured static route, the target packet does not switch the forwarding path any more, and does not consider the actual traffic situation in the network. When the selected static route path is just occupied by other business to cause congestion, the unselected static route link has residual bandwidth, thus the packet loss caused by unreasonable forwarding route selection is liable to cause the technical problem of low transmission efficiency.
According to the method, the final transmission path is comprehensively determined according to the residual bandwidth in the actual transmission path, the bandwidth required by the target message transmission and the priorities of the transmission paths, so that the network bandwidth is more fully utilized, and the transmission efficiency is improved.
It should be noted that in step 206, the transmission policy of the target packet is used to determine transmission rules, for example: selecting a proper path from a plurality of target transmission paths to transmit a target message, and the like.
According to the method and the device for transmitting the target message, the transmission strategy of the target message is determined according to the priority of the multi-item target transmission path, the bandwidth required by the target message transmission and the residual bandwidth of the multi-item target transmission path, so that the transmission path of the target message can be flexibly adjusted, and the effect of flexibly adjusting the transmission path in the network transmission process to provide transmission efficiency is achieved.
Steps S202 to S206 are specifically described below by way of examples.
In step S206, the transmission policy of the target message is determined by the following method, which specifically includes: determining a first transmission strategy of the target message based on the bandwidth required by the target message transmission and the residual bandwidth of the multi-label transmission path under the condition that the priorities of the multi-label transmission paths are the same; and under the condition that the priorities of the multi-entry target transmission paths are different, determining a second transmission strategy of the target message based on the priorities of the multi-entry target transmission paths, the bandwidth required by the target message transmission and the residual bandwidth of the multi-entry target transmission paths.
In the first case (the priority of the multi-label transmission paths is the same), it means that the multi-label transmission paths (static routes) are equivalent, and in the second case (the priority of the multi-label transmission paths is different), it means that the multi-label transmission paths (static routes) are non-equivalent.
In the first case, only the first transmission strategy of the target message is determined according to the bandwidth required by the transmission of the target message and the residual bandwidth of the multi-entry transmission path; in the second case, a second transmission policy of the target packet needs to be determined based on the priority of the multi-label transmission path, the bandwidth required for transmission of the target packet, and the remaining bandwidth of the multi-label transmission path.
The steps specifically include: comparing the bandwidth required by the target message transmission with the residual bandwidth of the multi-item target transmission path, and counting a first comparison result; determining the first transmission strategy based on the first comparison result; comparing the bandwidth required by the target message transmission with the residual bandwidth of the multi-item target transmission path, and counting a second comparison result; and determining the second transmission strategy based on the second comparison result and the priority of the multi-label transmission path.
It can be appreciated that the first comparison result and the second comparison result are both used to indicate the comparison result of the bandwidth required for the transmission of the target message and the remaining bandwidth of the multi-target transmission path.
In an optional manner, when the first comparison result indicates that the bandwidth required for transmitting the target message is smaller than the remaining bandwidth of each target transmission path in the multi-target transmission path, determining the first transmission policy to evenly distribute the target message to the multi-target transmission path and send the target message to a target server; determining the first transmission strategy to select a target transmission path with the largest residual bandwidth from the multi-item target transmission paths to send the target message under the condition that the first comparison result indicates that the bandwidth required for transmitting the target message is larger than the residual bandwidth of a first number of target transmission paths in the multi-item target transmission paths and smaller than the residual bandwidth of a second number of target transmission paths; and under the condition that the first comparison result indicates that the bandwidth required by the target message is larger than the residual bandwidth of each target transmission path in the multi-target transmission path, determining the first transmission strategy to distribute the bandwidth required by the target message transmission according to the ratio of the residual bandwidths of each target transmission path in the multi-target transmission path so as to send the target message.
In another optional manner, when the second comparison result indicates that the bandwidth required for transmitting the target packet is smaller than the remaining bandwidth of each target transmission path in the multi-target transmission paths, determining the second transmission policy to select a target transmission path with the highest priority from the multi-target transmission paths to transmit the target packet; determining that the second transmission strategy is to select a target transmission path with the largest residual bandwidth from the multi-item target transmission paths to transmit the target message under the condition that the second comparison result indicates that the bandwidth required for transmitting the target message is larger than the residual bandwidth of the target transmission path with the higher priority than the preset level in the multi-item target transmission paths and smaller than the residual bandwidth of the target transmission path with the lower priority than the preset level in the multi-item target transmission paths; and under the condition that the second comparison result indicates that the bandwidth required by the target message is larger than the residual bandwidth of each target transmission path in the multi-target transmission path, determining the second transmission strategy to distribute the bandwidth required by the target message according to the ratio of the residual bandwidths of each target transmission path in the multi-target transmission path.
After determining the transmission strategy of the target message according to the priority of the multi-item target transmission path, the bandwidth required by the target message transmission and the residual bandwidth of the multi-item target transmission path, the transmission rate of the target message can be acquired according to a preset acquisition period, and the transmission strategy of the target message is redetermined under the condition that the transmission rate of the target message is lower than the preset transmission rate.
Specifically, when a path selected by the residual bandwidth mode before has congestion, the residual bandwidths of a plurality of target paths need to be checked again, and the forwarding paths are reselected, so that the specific transmission strategy is consistent with the method and is not repeated herein.
In some embodiments of the present application, in the case of an equal cost path:
case 1: the required rate (bandwidth) of the data message (target message) to be forwarded is smaller (smaller than the residual bandwidth of each link of the equivalent path), and then the data message to be forwarded is equally divided on each equivalent path according to the equivalent path forwarding principle.
Case 2: the data message rate to be forwarded is larger (the data message rate is larger than the residual bandwidth of some equivalent paths but smaller than the bandwidth of some equivalent links), then a link with the largest residual bandwidth path is selected, and the rest paths can not be used for forwarding the service.
Case 3: the data message to be forwarded has a very high rate, or the residual bandwidth of all forwarding paths is not much. (greater than the residual bandwidth of all equivalent links), then the message forwarding rate is proportionally distributed according to the ratio of the residual bandwidth of the links.
Case 4: when there is a link congestion in the path previously selected by the residual bandwidth method, the residual bandwidth of the link needs to be checked again at this time, and the forwarding path is reselected (rerouting continues with reference to cases 1, 2 and 3).
In some embodiments of the present application, the non-equivalent routing case:
case 5: the data message rate required to be forwarded is smaller (smaller than the residual bandwidth of each link), and then the path with the highest priority is selected for the target message required to be forwarded according to the static route selection principle.
Case 6: the data message rate to be forwarded is larger (larger than the residual bandwidth of the high-priority path but smaller than the residual bandwidth of some low-priority links), then a link with the largest residual bandwidth path is selected at this time, and the rest paths can not be used for forwarding the service.
Case 7: the data message to be forwarded has a very high rate, or the residual bandwidth of all forwarding paths is not much. (greater than the residual bandwidth of all links), then the message forwarding rate is proportionally distributed according to the ratio of the residual bandwidth of the links.
Case 8: when a path selected by the residual bandwidth mode forwards for a period of time, if a link congestion occurs, the residual bandwidth of the link needs to be checked again at the moment, and a forwarding path is reselected (rerouting continues to refer to cases 5, 6 and 7); if no link congestion condition occurs, the path previously selected by the residual bandwidth mode is kept.
Fig. 3 shows a schematic diagram of a network topology, as shown in fig. 3, where a plurality of virtual machines VM1, VM2 … VM31, a plurality of relay servers and a plurality of switches are respectively configured in different network segments.
In an exemplary embodiment, after the target message is sent to the relay server TOR1 by VM1, the static routing table is checked on TOR1, and paths to the target network segment are TOR1- > SW1 and TOR1- > SW2. Since the bandwidths of TOR1 to SW1 and TOR1 to SW2 are both 40G, the priorities of both routes are set to be the same, for example, 1, and at this time, the two static routes TOR1- > SW1 and TOR1- > SW2 are equivalent routes. However, the optimal route forwarded from VM1 to VM21 also needs to be calculated by judging the traffic on the actual network, for example: VM1 through VM21 require 10Gbps bandwidth, the TOR1- > SW1 path is now already occupied by other traffic for 38Gbps (40G-38G=2G remaining), and the TOR1- > SW2 path is not occupied by any other traffic (40 Gbps remaining). Then the routing scheme in case 2 of the equivalent routing is adopted at this time, and the path TOR1- > SW2 is selected as the optimal path for forwarding the traffic. After a period of time, if other traffic of the path TOR1- > SW2 increases to affect the traffic forwarding from VM1 to VM21, then actively checking the bandwidth surplus condition of the path TOR1- > SW1, for example, when the bandwidth surplus condition of 4Gbps is left, and allocating the traffic from VM1 to VM21 to the path TOR1- > SW 1.
In one exemplary embodiment, VM21 to VM1 forwarding flow: after the message is forwarded to TOR2 by VM21, the static routing table is checked on TOR2, and the paths of the checked destination network segments are TOR2- > SW1 and TOR2- > SW2. Since the bandwidths of TOR2 to SW1 and TOR2 to SW2 are 40G and 100G, respectively, the priority settings for setting the two routes are different, for example, TOR2 to SW1 are set to 3, TOR2 to SW2 are set to 1, and at this time, the two static routes TOR2- > SW1 and TOR2- > SW2 are non-equivalent static routes. However, the optimal route forwarded by VM21 to VM1 also requires determining the traffic on the actual network to calculate:
for example, VM21 to VM1 requires 10Gbps bandwidth, the TOR2- > SW1 path is now already occupied 34Gbps by other traffic (40G-34 G=6G remaining), and the TOR2- > SW2 path is occupied 96G by other traffic (100G-96 G=4G remaining). Then according to the non-equivalent path case 3 (divided according to the ratio of the residual bandwidths), the residual bandwidths are 3:2 at the moment, and the forwarding rate of the path TOR2- > SW1 is selected to be [ 3/(3+2) ]x10g=6g at the moment. At this time, TOR2- > SW1 is selected and this path forwards [ 2/(3+2) ], 10g=4g. After a period of time, if other services of the TOR2- > SW1 path are increased, and service forwarding from the VM21 to the VM1 is affected, at this time, the bandwidth residual condition of the TOR2- > SW2 path is actively checked, and the forwarding path is reselected according to the residual bandwidth condition.
