[0040] Through the above steps, the switch includes a controller and multiple switches, the controller is connected to each switch respectively, the switch is used to transmit message data between network devices, the controller receives the target message to be forwarded and the message information for indicating the forwarding mode of the target message sent by the first switch among the multiple switches, and then selects the second switch from the multiple switches according to the switch information and message information for indicating the current message forwarding service load of the switch, and controls the second switch to perform the forwarding operation corresponding to the message information on the target message, that is, the controller will select the appropriate second switch to complete the forwarding operation of the target message according to the current message forwarding service load of each switch and the forwarding mode of the target message after any switch receives the target message to be forwarded, so as to avoid the situation that other switches are in a relatively idle state when one switch undertakes too many message forwarding tasks, avoid the waste of message forwarding resources of the switch, and improve the forwarding efficiency of the message. The above technical solution solves the problems of low message forwarding efficiency in the related technology and achieves the technical effect of improving the forwarding efficiency of the message.

[0041] Optionally, in an embodiment of the present application, including but not limited to, multiple processor cores are arranged in the switch, the master core is the controller, and the multiple slave cores are multiple switches.

[0042] In the technical solution provided in the above step S202, the message information is used to indicate the forwarding method of the target message, which may include but is not limited to the length of the message and whether the message needs to be looped back.

[0043] Optionally, in this embodiment, including but not limited to receiving the target message and the message information of the target message sent by the first switch when the business of the switch is relatively busy, and not receiving the target message and the message information when the business is relatively idle. In this way, when the load pressure of a single switch is too large and other switches are idle, the controller intervenes to balance the load, and when the overall pressure is relatively low, each switch itself directly completes the task of forwarding the received message.

[0044] Optionally, in an embodiment of the present application, including but not limited to detecting switch information, when it is detected that the message forwarding service load indicated by the switch information exceeds the service load capacity of the message forwarding service that can be undertaken by a single switch, receiving the target message and message information of the target message sent by the first switch among multiple switches.

[0045] In the technical solution provided in the above step S204, the switch information is used to indicate the current message forwarding service load of the switch, which may include but is not limited to the length of the message processed by the switch or the data volume of the message.

[0046] Optionally, in this embodiment, selecting a second switch from multiple switches based on the switch information and message information of each switch includes but is not limited to selecting a switch with the smallest message forwarding service load indicated by the switch information from multiple switches as the second switch based on the switch information; or detecting whether the target message is a message that needs to be looped back based on the message information, and when it is detected that the target message is a message that needs to be looped back, selecting switches that can implement the loopback function from multiple switches to obtain a switch set, and then selecting the second switch from the switch set based on the switch information in the switch set.

[0047] In the technical solution provided in the above step S206, controlling the second switch to perform a forwarding operation corresponding to the message information on the target message includes but is not limited to sending the target message and the message information to the second switch, and the second switch is configured to process and forward the message according to the received message and the message information of the message.

[0048] In an exemplary embodiment, a second switch is selected from multiple switches based on switch information and message information of each switch, including: detecting prediction information of each switch based on message information and switch information, wherein the prediction information is used to indicate the message forwarding service load status of the switch after currently undertaking the forwarding operation task of the target message; and selecting the second switch from multiple switches based on the switch information and the prediction information.

[0049] Optionally, in the embodiment of the present application, the prediction information is used to indicate the message forwarding service load of the switch after the forwarding load of the target message is added to the current load of the switch. Based on the acquisition of the prediction information, the second switch that performs the forwarding operation is selected with the help of the prediction information, so that if there is a target message that will cause the switch to be overloaded, the forwarding task of the target message will be processed by the switch that receives the target message, thereby reducing the impact on other messages to be forwarded.

[0050] In an exemplary embodiment, a second switch is selected from a plurality of switches according to switch information and prediction information, including: extracting a switch with the smallest switch parameter from a plurality of switches according to switch parameters of each switch to obtain a reference switch, wherein the switch parameter is used to indicate the data volume of a message to be processed by the switch, and the switch information includes the switch parameter; detecting the size relationship between the switch parameter of the reference switch and the message threshold of the reference switch; in the case where it is detected that the switch parameter of the reference switch is less than or equal to the message threshold, determining the first switch as the second switch; in the case where it is detected that the switch parameter of the reference switch is greater than the message threshold, detecting the size relationship between the prediction parameter of the reference switch and the message threshold, wherein the prediction parameter is used to indicate the data volume of a message to be processed after the reference switch currently undertakes a forwarding operation task, and the prediction information includes the prediction parameter; in the case where it is detected that the prediction parameter is greater than or equal to the message threshold, determining the reference switch as the second switch; in the case where it is detected that the prediction parameter is less than the message threshold, determining the first switch as the second switch.

[0051] As an optional implementation, screening out a second switch from multiple switches based on the switch information and message information of each switch includes extracting a switch with the smallest switch parameter from multiple switches based on the switch parameters of each switch to obtain a reference switch, wherein the switch parameter is used to indicate the data volume of the message to be processed by the switch, and the switch information includes the switch parameter; detecting the size relationship between the switch parameter of the reference switch and the message threshold of the reference switch; when it is detected that the switch parameter of the reference switch is less than or equal to the message threshold, determining the first switch as the second switch; when it is detected that the switch parameter of the reference switch is greater than the message threshold, determining the reference switch as the second switch.

[0052] In an exemplary embodiment, the method also includes: detecting whether the information refresh opportunity has arrived; when it is detected that the information refresh opportunity has arrived, refreshing the switch information of each switch according to the capability information of each switch, wherein the capability information is used to indicate the status of the messages that the switch can forward and process within the time period from the time when the last refresh opportunity arrived to the time when the current refresh opportunity arrived.

[0053] Optionally, in this embodiment, it includes but is not limited to setting the next refresh opportunity to arrive at a fixed time interval after the arrival of a refresh opportunity, or setting the next refresh opportunity to arrive at any time after completing the refresh of the switch information of each switch according to actual usage requirements.

[0054] Optionally, in an embodiment of the present application, the capability information of each switch may be fixed, or may be constantly changing according to changes in the network environment, and the present application does not limit this.

[0055] In an exemplary embodiment, the switch information of each switch is refreshed according to the capability information of each switch, including: detecting the size relationship between the operating parameters and refresh parameters of each switch, wherein the operating parameters are used to indicate the data volume of the message to be processed by the switch, and the refresh parameters are used to indicate the data volume of the message that can be forwarded and processed by the switch within a time period, the capability information includes the refresh parameters, and the switch information includes the operating parameters; when it is detected that the operating parameters are greater than or equal to the refresh parameters, calculating the difference between the operating parameters and the refresh parameters to obtain a first refresh value; refreshing the switch information using the operating parameters replaced by the first refresh value; when it is detected that the operating parameters are less than the refresh parameters, determining the second refresh value to be 0; and refreshing the switch information using the operating parameters replaced by the second refresh value.

[0056] Optionally, in this embodiment, Figure 3 1 is a flow chart of a method for refreshing switch information according to an embodiment of the present application. Figure 3 As shown, a load refresh timer module can be set on the controller to be responsible for periodically refreshing the load value (i.e., operating parameter) of each of the (M+1) slave cores (i.e., slave core 0 to slave core M) by subtraction. The purpose is to make the load value truly reflect the load situation of the slave core within the cycle. If this operation is not performed, the load value will only be accumulated. When the message flow stops after a period of time on some slave cores, if this load value is not refreshed and reduced, it will cause the switch selection error. By continuously reading each slave core load register and each slave core load refresh value register to obtain the current load value of each slave core and the refresh value of each slave core to update the load value of each slave core, the correct switch selection can be ensured.

[0057] In an exemplary embodiment, a switch includes a first engine and a second engine, the first engine is connected to the second engine, and the first engine and the second engine are both connected to a controller, the first engine is used to receive a first message to be processed and parse the first message to obtain first information indicating a forwarding mode of the first message and send the first message and the first information to the controller, the second engine is used to receive a second message to be processed sent by the controller and forward the second message according to the second information of the second message indicating a forwarding mode of the second message, before the second switch is screened out from a plurality of switches according to the switch information and message information of each switch, the method also includes: receiving a first parameter sent by the first engine and a second parameter sent by the second engine, wherein the first engine is configured to send a first parameter to the controller when receiving the first message, the first parameter is used to indicate a message data volume of the first message, and the first information includes the first parameter, the second engine is configured to send a second parameter to the controller when receiving the second message, the second parameter is used to indicate a message data volume of the second message, and the second information includes the second parameter; and updating the switch information according to the first parameter and the second parameter.

[0058] Optionally, in this embodiment, Figure 4 is an architectural diagram of a message forwarding method according to an embodiment of the present application, Figure 5 is a schematic diagram of a switch information maintenance method according to an embodiment of the present application, such as Figure 4 and Figure 5 As shown, each switch (i.e., slave core) includes a first engine (i.e., IPE) and a second engine (EPE), and a loopback channel, i.e., Slice0-SliceM, is provided between the first engine and the second engine, and the second engine can forward the second message to the first engine in the same switch through the loopback channel. A master core receiving slave core load information module can also be provided in the controller (i.e., the master core), and a slave core information sending module can be provided in the first engine and the second engine of each switch, and the slave core information sending module is responsible for sending the message length information passing through the slave core to the master core in real time, and the master core receiving slave core load information module is responsible for saving the message length information sent from the slave core according to the slave core number.

[0059] In an exemplary embodiment, the second switch includes a third engine and a fourth engine, the third engine is connected to the fourth engine, and the third engine and the fourth engine are both connected to a controller; the second switch is controlled to perform a forwarding operation corresponding to the message information on the target message, including: detecting the forwarding requirement of the target message according to the message information, wherein the forwarding requirement is used to indicate whether the target message needs to be looped back; when it is detected that the forwarding requirement is used to indicate that the target message needs to be looped back, sending a first instruction to the fourth engine, wherein the first instruction is used to instruct the fourth engine to forward the received target message to the third engine, and the third engine is used to forward the target message to the controller when the target message is received; when it is detected that the forwarding requirement is used to indicate that the target message does not need to be looped back, sending a second instruction to the fourth engine, wherein the second instruction is used to instruct the fourth engine to forward the received target message to the next hop device connected to the switch.

[0060] As an optional implementation, Figure 6 FIG. 1 is a flow chart of a loopback message forwarding method in a multi-core architecture according to an embodiment of the present application. Figure 6 As shown in the figure, if the message to be forwarded is a loopback message, when the loopback message passes through the main core (i.e., the controller), the routing logic will be triggered, and the loopback channel selection module will select the loopback path based on the loopback path selection logic. Figure 6 The logic is to select the slave core (minLoadSlice) (i.e., the switch) with the minimum load (minLoad) according to the current load (curLoad) of each slave core. If the load of the selected slave core exceeds the RegLoadThrd configured by the CPU (the CPU configures the bandwidth threshold upper limit for each slave core), the slave core that receives the forwarded message is selected, otherwise the minLoadSlice is selected, and the loopback message is forwarded to the EPE of the selected slave core and then returned to the IPE of the selected slave core. For example, when the load of the selected minLoadSlice exceeds the 2T bps configured by the CPU, it is considered that it has exceeded the bandwidth capacity of the current slave core. At this time, the loopback message is still looped back from its original forwarding core. Through the above steps, the problem of packet loss caused by the loopback message on each core can be effectively balanced.

[0061] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software and a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods of each embodiment of the present application.
