Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a method and device for transmitting message data, a storage medium, and an electronic device. Background Art

[0002] In network forwarding, there may be multiple paths for message data to reach the destination from the current hop. If the costs of these paths are the same (the costs may include the number of devices to be passed, the number of routes, the time, etc.), these paths constitute an ECMP (Equal Cost Multiple Path) group, and each path is a member of the ECMP group. The switching chip will select data streams to forward to different members according to the current traffic load of each member to achieve load sharing. If a member's link fails, the data needs to be switched to other unfaulted paths to prevent a large number of packet losses from causing service interruptions.

[0003] In a network switching device composed of multiple stacked switching chips, there is a situation where the local chip port and the remote chip port (i.e., not the local chip) are in the same ECMP group. At this time, if the remote chip port fails or the service is overloaded, the local chip needs to switch the message data to other normal paths for forwarding to prevent the loss of message data from causing service interruption. In the related technology, since the local chip cannot perceive the abnormal situation of the remote chip port in real time, the remote chip needs to interrupt the current service and notify the main control CPU (Central Processing Unit) of the network switching device, and then the main control CPU notifies the local chip to switch the data link, and then selects other normal ports for message data transmission. This switching time can be as long as hundreds of milliseconds, resulting in low transmission efficiency of message data.

[0004] With regard to the problem of low transmission efficiency of message data in related technologies, no effective solution has been proposed yet. Summary of the invention

[0053] In this embodiment, a method for transmitting message data is provided, which is applied to the above-mentioned computer terminal. Figure 2 1 is a flow chart of a method for transmitting message data according to an embodiment of the present application, and the flow includes the following steps:

[0054] Step S202, receiving a data transmission request, wherein the data transmission request is used to request to send target message data to other network devices;

[0055] Step S204, in response to the data transmission request, obtaining port status data sent by a reference processor, wherein the reference processor is a processor configured on a reference switching chip other than the target switching chip among the plurality of switching chips, and the port status data is used to indicate a message transmission status of a message transmission port included in the corresponding switching chip;

[0056] Step S206, updating the initial state table on the target switching chip according to the port state data to obtain a target state table, wherein the initial state table records the message transmission state of the message transmission port included in each of the switching chips in the plurality of switching chips;

[0057] Step S208: Screening out a candidate switch chip for transmitting the target message data from a plurality of switch chips according to the target state table.

[0058] Through the above steps, a processor is configured on each of the multiple switching chips deployed on the network switching device, and the processors of different switching chips are associated with each other. Therefore, before the target switching chip transmits the message data, it can obtain the port status data sent by the processor configured on the reference switching chip through the processor configured on the target switching chip, and then query the message transmission status of the message transmission port included in the corresponding switching chip according to the port status data, and then update the initial state table on the target switching chip according to the port status data to obtain the target state table, and then screen out the candidate switching chips for transmitting the target message data from the multiple switching chips according to the target state table, so that the switching chip can directly perform data interaction through the processor configured on the switching chip. This process does not require the participation of the main control CPU in the network switching device, and only needs to monitor the message transmission status of the message transmission port included in the current switching chip in real time through the processor configured on the switching chip, and then synchronize and update the initial state table on the target switching chip, thereby realizing the rapid switching of the message data forwarding path of the target switching chip, avoiding the delay problem caused by the third device transmitting the port status data in the related technology, and improving the transmission efficiency of the message data. The above technical solution solves the problem of low transmission efficiency of message data in related technologies and achieves the technical effect of improving the transmission efficiency of message data.

[0059] In the embodiment provided in the above step S204, the message transmission state of the message transmission port can be used, but not limited to, to characterize whether the corresponding message transmission port can normally perform the message transmission service, that is, the port state data includes data for whether the message transmission port is currently in a fault state. The message transmission state can also be used to characterize the execution of the message transmission service by the corresponding message transmission port, so the port state data includes the service load of the message transmission port, the message transmission rate, etc., which is not limited in this solution.

[0060] Optionally, in an embodiment of the present application, the port status data sent by the reference processor can be obtained by sending a status acquisition request to the reference processor, that is, when the target processor detects that the port status data of the reference switching chip is needed, it sends a status acquisition request to the processor deployed on the corresponding switching chip, and then queries the current operating status of the message transmission port on the reference switching chip, and then converts the port status data of the reference switching chip according to the target response information sent by the reference processor. The target processor detects whether the port status data of the reference switching chip is needed by: detecting the update status of the port status data of the reference switching chip in the status table recorded in the target switching chip, and the update status indicates the time interval between the update time of the port status data of the reference switching chip and the current moment. When the time interval is greater than the target time interval, it is determined that the reference switching chip needs to be obtained. Port status data; in this embodiment, it can be obtained by querying the port operation log recorded in the reference switching chip, which can be achieved in the following ways: sending a log acquisition request to the reference processor, the log acquisition request is used to request to obtain the port operation log generated by the reference switching chip, the port operation log records the port operation status information of the message transmission port included in the reference switching chip; converting the data format of the port operation log to obtain a target operation log, the data format of the target operation log is an internal data format that can be directly processed by the processor; traversing each field in the target operation log, extracting the field value of the status field corresponding to the message transmission port included in the reference switching chip, the status field is used to indicate the operation status of the message transmission port included in the reference switching chip; converting the port status data of the reference switching chip according to the field value of the status field.

[0061] In the embodiment provided in the above step S206, the initial state table is a data storage structure for recording the real-time or historical operation state data of each message transmission port on all switch chips in the network switching device. Such data may include, but is not limited to, the operation state of the port (normal, faulty, maintenance-medium), the fault type (such as open circuit, short circuit, logic error, electrical performance degradation, etc.), the time when the fault occurred, the recovery time (if it has been recovered), and possible fault causes.

[0062] Optionally, in an embodiment of the present application, after receiving the port status data sent by the reference processor, the initial status table on the target switching chip needs to be updated according to the port status data. When the port status data indicates port fault data, the initial fault data of the corresponding port in the initial status table on the target switching chip is updated; when the port status data indicates message transmission data, for example, a port on the reference switching chip may have a service overload or transmission error, the initial message transmission data of the corresponding port in the initial status table on the target switching chip is updated.

[0063] Optionally, in an embodiment of the present application, updating the initial state table on the target switching chip according to the port status data can also be achieved by parsing the port status data according to a protocol pre-agreed between the chips, and the implementation steps are as follows: S1: According to the protocol and data format pre-agreed between the target switching chip and the reference switching chip, the port status data sent by the reference processor is parsed to extract the current status information of each port included in the reference switching chip; S2: Based on the port status data obtained by the analysis, the corresponding entry is queried in the initial state table according to the port identifier corresponding to each port in the reference switching chip; S3: After finding the corresponding entry, the status information of the entry is updated according to the port status data. If the port status becomes inactive or faulty, the status of the entry is marked as unavailable; if the port resumes the active state, the status of the entry is marked as available.

[0064] In the embodiment provided in the above step S208, after the initial state table is updated to the target state table, it is necessary to reselect the candidate switching chip for transmitting the message data in the target state table, which can be to first filter out the message transmission ports in the target state table that are in normal operation, and then prioritize the filtered normal message transmission ports to obtain a port sequence, and then extract the reference message transmission ports that meet the sorting conditions from the sequence, and finally determine the switching chip to which the reference message transmission port belongs as the candidate switching chip. Then, the target message data can be transmitted to the candidate switching chip, and the candidate switching chip selects the message transmission port for transmitting the target message data according to its own load condition, thereby improving the transmission efficiency of the target message data.

[0065] As an optional embodiment, obtaining the port status data sent by the reference processor includes:

This solution does not limit this.

[0070] Optionally, in an embodiment of the present application, after receiving a data transmission request, the target processor will first detect the status update status of the message transmission ports included on each switching chip, and then trigger a status acquisition request when the port status information is not the latest information. In this way, the data transmission pressure caused by sending status acquisition requests to all reference processors can be effectively avoided, which can be achieved through the following steps: obtaining status update information of the reference processor, the status update information is used to indicate the status update status of the message transmission port included on the reference switching chip; extracting a status identifier corresponding to each message transmission port in the reference switching chip from the status update information, the status identifier is used to indicate whether the status information of the corresponding message transmission port is the latest information; when the status identifier is used to indicate that the status information of the corresponding message transmission port is not the latest information, sending a status acquisition request to the reference processor.

[0098] Optionally, in an embodiment of the present application, sub-data is used to characterize the transmission performance of the initial message transmission port when performing message transmission services from multiple dimensions.

[0101] In order to better understand the above process, the above process is described below in conjunction with an optional embodiment, but it is not intended to limit the technical solution of the embodiment of the present application.

[0102] In this embodiment, a method for fast ECMP switching in a stacking scenario is provided. The basic idea of ​​this method is to use the built-in CPU of the chip to implement link monitoring between stacked chips and fast switching of link status of ECMP group members. Figure 3 A schematic diagram of a method for fast ECMP switching in a stacking scenario according to an embodiment of the present application Figure 1 ,like Figure 3 As shown in the figure, each switch chip has a built-in small CPU. The built-in CPU is limited by memory size and other reasons, so it cannot complete complex logic like the main CPU, but its interaction speed with the chip is faster than that of the main control CPU. Since the logic required for link monitoring and state switching is not complex, the built-in CPU of the chip can be responsible for executing this logic, which mainly includes the following steps:

[0103] Step S301: There are three members in the ECMP Group: Port 1 and Port 2 of CHIP 1 and Port 3 of CHIP 2. The message enters from CHIP 1 and is originally forwarded from Port 3.

[0104] Step S302: Port 3 fails and forwarding is unavailable. The built-in CPU of CHIP 2 quickly senses the state change and organizes a message to send to the built-in CPU of CHIP 1 to notify the change.

[0105] Step S303: The built-in CPU of CHIP 1 receives the message, senses the state change of CHIP 2, and sends a configuration to modify the member state table of ECMP. The port state of Port 3 is changed to a fault state, and CHIP 1 automatically selects other members that are not faulty for forwarding subsequent traffic (the total time from the failure of Port 3 to the selection of traffic forwarding to the new member is sub-millisecond level);

[0106] Step S304: When Port 3 resumes working, the built-in CPU of CHIP 2 will also notify the built-in CPU of CHIP 1 to modify the ECMP member status table back to its original state.

[0107] In the above embodiment, from the working principle of the chip, the chip has a member status table, which records the link status of the ECMP group members. If the status is down, the chip automatically forwards the traffic to other members that are not faulty. For the member ports of this chip, the chip can automatically monitor their status and realize automatic switching after the port fails, but for the link status record of the remote member, it can only be perceived by the main control CPU and then sent down for configuration modification.

[0108] Figure 4 A schematic diagram of a method for fast ECMP switching in a stacking scenario according to an embodiment of the present application Figure 2 ,like Figure 4 As shown in the figure, the built-in CPU of the chip monitors the local port status in real time. Once a change occurs, it sends a message through the chip interconnection port to notify the built-in CPU of the remote chip. In this way, in a stacking scenario, the local chip monitors the port status of the remote chip. According to the monitoring situation, the built-in CPU modifies the ECMP member status table of its own chip to achieve fast traffic switching.

[0109] 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.
