[0046] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0048] The present invention provides a method, apparatus, computer device, and computer-readable storage medium for switching between active and standby high-speed signal circuits. The method can be applied to a computer device, such as a laptop computer or desktop computer.

[0049] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0050] Please refer to Figure 2 , Figure 2 A flowchart of a method for switching between active and standby high-speed signal circuits provided in an embodiment of the present application is provided.

[0051] like Figure 2 As shown, the method includes steps S101 to S105.

[0052] Step S101: Receive status indication information, and determine master and backup information of a master system and a backup system according to the status indication information.

[0053] Exemplarily, status indication information sent by a receiving system side is received, and the status indication information includes status indication information of a primary system and status indication information of a backup system. For example, the status indication information of the primary system includes primary presence indication information of the primary system, and the status indication information of the backup system includes backup presence indication information of the backup system. After receiving the status indication information sent by the system side, primary and backup information of the primary and backup systems are determined based on the status information, wherein the primary and backup information includes the primary state and the backup state.

[0054] Specifically, receiving the status indication information includes receiving, through the CPU, the status indication information sent by the primary system and / or the backup system.

[0055] Exemplary, such as Figure 3 As shown, the main presence indication signal and the standby presence indication signal on the system side are connected to the CPU in advance, respectively. Through the main presence indication signal and the standby presence indication signal on the system side, the CPU receives the main system or standby system status indication information on the system side.

[0056] Specifically, read the mark information carried in the status indication information, wherein the mark information includes a main status mark and a backup status mark; if the status information is a main status mark, determine whether the main system is in the main status or the backup status; if the status information is a backup status mark, determine whether the backup system is in the main status or the backup status.

[0057] Exemplarily, upon receiving real-time status information, the marking information carried in the status indication information is read, wherein the marking information includes a primary status mark and a backup status mark, which may be marked in color, text, or other marking methods. When the status information obtained is the primary status mark, the primary system is determined to be in the primary state or the backup state. For example, the status information is pre-configured so that when the primary status mark is obtained, the primary system is determined to be in the primary state, or when the primary status mark is obtained, the primary system is determined to be in the backup state. When the status information obtained is the backup status mark, the backup system is determined to be in the primary state or the backup state. For example, the status information is pre-configured so that when the backup status mark is obtained, the backup system is determined to be in the primary state, or when the backup status mark is obtained, the backup system is determined to be in the backup state. There is only one primary state and one backup state in the primary and backup systems. For example, when the primary system is in the primary state, the backup system is in the backup state; or when the backup system is in the primary state, the primary system is in the backup state.

[0058] Step S102: Determine whether the current primary system should be switched with the current backup system based on the primary and backup information of the primary and backup systems.

[0059] Exemplarily, obtain the master-slave information of the main system, the master-slave information of the backup system, the master-slave information of the current main system, and the master-slave information of the current backup system, compare the master-slave information of the main system with the master-slave information of the current main system, and determine whether the current main system is switched with the current backup system; or compare the master-slave information of the backup system with the master-slave information of the current backup system to determine whether the current device is switched with the current backup system. For example, when the master-slave information of the main system is consistent with the master-slave information of the current main system, it is determined that the current main system is switched with the current backup system; or, when the master-slave information of the backup system is consistent with the master-slave information of the current backup system, it is determined that the current main system is switched with the current backup system. Figure 3 As shown, the CPU and the SWITCH device are connected through a PCIE interface. After receiving the status indication information, the CPU determines whether the current main system and the current backup system are switched based on the status indication information.

[0060] Specifically, the first data packet sent by the main system or the backup system is received according to the preset downlink packet processing flow rules, including: if the current main system is in the main state, determining that the main system is in the backup state, and then determining that the current main system and the current backup system are switched; if the current backup system is in the backup state, determining that the backup system is in the main state, and then determining that the current main system and the current backup system are switched.

[0061] Exemplarily, the master / slave information includes the master status of the master system. If the master system is determined to be the master / slave and the current master system is found to be in the standby status, then a switchover between the current master system and the current standby system is determined. The master / slave information includes the standby status of the standby system. If the standby system is determined to be the master / slave and the current standby system is found to be in the standby status, then a switchover between the current master system and the current standby system is determined.

[0062] Step S103: If it is determined that the current primary system and the current backup system are switched, a preset ACL table is obtained, wherein the preset ACL table includes a preset uplink packet processing flow rule and a preset upstream packet processing flow rule.

[0063] Exemplarily, when it is determined that the current primary system and the current backup system are switched, a switching request is generated, and a preset ACL table is obtained through the switching request, wherein the preset ACL table includes a preset uplink packet processing flow rule and a preset upstream packet processing flow rule.

[0064] Step S104: Receive a first data packet sent by the primary system or the backup system according to the preset downlink packet processing flow rule.

[0065] Exemplarily, when a preset downlink packet processing flow rule in a preset ACL table is obtained, the first data packet sent by the primary system or the backup system is received through the preset downlink packet processing flow rule. For example, when it is determined that the primary system after switching is in the primary state, the primary system sends the first data packet through the first port, the backup system sends the first data packet through the second port, the first data packet sent by the primary system through the first port is received, and the first data packet sent by the backup system through the second port is discarded; or, when it is determined that the backup system after switching is in the primary state, the backup system sends the first data packet through the first port, the primary system sends the first data packet through the second port, the first data packet sent by the backup system through the first port is received, and the first data packet sent by the primary system through the second port is discarded.

[0066] Specifically, the receiving of the first data packet sent by the main system or the backup system according to the preset downstream packet processing flow rule includes: if it is determined that the main system is in the main state after the switching, the preset downstream packet processing flow rule is used to enable the first port or the second port to receive the first data packet sent by the main system; if it is determined that the backup system is in the main state after the switching, the preset downstream packet processing flow rule is used to enable the first port or the second port to receive the first data packet sent by the backup system.

[0067] Exemplarily, when it is determined that the main system is in the main state after the switch, by presetting the downlink packet processing flow rules, the first port corresponding to the main system receives the first data packet sent by the first port, and discards the first data packet sent by the second port corresponding to the backup system; or, the second port corresponding to the main system receives the first data packet sent by the second port, and discards the first data packet sent by the first port corresponding to the backup system.

[0068] Step S105: forwarding the second data packet sent by the preset SWITCH device to the primary system or the backup system according to the preset uplink packet processing flow rule.

[0069] Exemplarily, when the main system is determined to be in the main state, the second data sent by the preset SWITCH device is forwarded to the main system through the first port or the second port through the preset uplink packet processing flow rule; or, when the backup system is determined to be in the main state, the second data sent by the preset SWITCH device is forwarded to the backup system through the first port or the second port through the preset uplink packet processing flow rule.

[0070] Specifically, before the receiving status indication information, it also includes: when detecting that the preset SWITCH device is initialized, configuring the ACL table according to the preset uplink packet processing flow rule and the preset downlink packet processing flow rule to generate a configured preset ACL table; wherein the preset downlink packet processing flow rule includes if the main system is in the main state, then determining that the first port or the second port receives the first data packet, or if the standby system is in the main state, then determining that the first port or the second port receives the first data packet; the uplink packet processing flow rule includes if the main system is in the main state, then the main system receives the second data packet forwarded by the preset SWITCH device through the first port or the second port, or the uplink packet processing flow rule includes if the standby system is in the main state, then the standby system receives the second data packet forwarded by the preset SWITCH device through the first port or the second port.

[0071] For demonstration purposes, when the preset SWITCH device is detected to be initialized, the ACL table is configured through the preset uplink packet processing flow rules and the preset downlink packet processing flow rules to generate the configured preset ACL table. The SWITCH device has multiple external access interfaces, flexible and fast ACL table entry control, and diversified packet processing rules, such as Figure 3 As shown, the PCIE interface is connected to the external CPU interface. For example, the CPU starts running, and after setting its own operating parameters and configuring the external communication interface and interrupt interface parameters, it starts initializing the SWITCH device. The preset downlink packet processing flow rule includes: when the main system is in the main state, the first port allows the reception of packets and can forward processing, and the second port discards all packets received; when the main system is in the standby state, the first port discards all packets received, and the second port allows the reception of packets and can forward processing. For example, when the main system is in the main state, the C1 port allows the reception of packets and can forward processing, and the C2 port discards all packets received; when the main system is in the standby state, the C1 port discards all packets received, and the C2 port allows the reception of packets and can forward processing. The preset uplink packet processing flow rule includes: if the main system is in the main state, determining whether the first port or the second port receives the first data packet, or if the standby system is in the main state, determining whether the first port or the second port receives the first data packet. For example, after the CPU initializes the SWITCH device, it configures the SWITCH device to flood the second data packet to the upstream aggregation ports, namely, the C1 port and the C2 port. When the master system is in the master state, the second data packet is received through the C1 port corresponding to the master system, or, the second data packet is received through the C2 port corresponding to the master system; or, when the standby system is in the master state, the second data packet is received through the C1 port corresponding to the standby system, or, the second data packet is received through the C2 port corresponding to the standby system.

[0072] In an embodiment of the present application, by presetting the downlink packet processing flow rules and the uplink packet processing flow rules, the first data packet sent by the main system or the backup system after the switching is received, and the second data packet is sent to the main system and the backup system. While reducing the hardware, not only the stability and real-time response speed are improved, but also the packet loss caused by the switching is avoided.

[0073] Please refer to Figure 4 , Figure 4 A flowchart of another method for switching between active and standby high-speed signal circuits is provided for an embodiment of the present application.

[0074] like Figure 4 As shown, the process includes steps S201 to S203.

[0075] Step S201: interrupt the current process of the primary system or the backup system receiving and sending data packets, generate a switching process, and determine the priority of the switching process.

[0076] Exemplarily, when it is determined that the current primary system and the backup system need to be switched, a switching request is generated, and the process of the current primary system or backup system receiving and sending data packets is interrupted through the switching request. A switching process is generated through the switching request, and the priority of the switching process is determined, wherein the data includes a first data packet and a second data packet, and the method of interrupting the process of the current primary system or backup system receiving and sending data packets includes interrupting the primary system or backup system from sending the first data packet and interrupting the primary system or backup system from receiving the second data packet. The interrupt method includes, after an interrupt pin in the CPU detects the switching request, searching a preset interrupt vector table and interrupting the process of the current primary system or backup system receiving and sending data packets through the preset interrupt vector table.

[0077] Determine the priority of the switching process, obtain all currently generated processes, sort all the processes, determine the processing order of each process by sorting, mark the switching process as the first order, and give priority to the switching process; or, unlock other current processes to lock the switching process, and give priority to the switching process by locking the switching process.

[0078] Step S202: Based on the priority of the switching process, the switching process is processed preferentially.

[0079] Exemplarily, the priority of the switching process is determined so that the switching process is processed first.

[0080] Step S203: Acquire a preset ACL table by processing the switching process, wherein the preset ACL table includes a preset uplink packet processing flow rule and a preset upstream packet processing flow rule.

[0081] Exemplarily, after processing the switching process, a preset ACL table is obtained, wherein the preset ACL table includes a preset upstream packet processing flow rule and a preset upstream packet processing flow rule. The first data packet sent by the main system or the backup system is received through the preset downstream packet processing flow rule. For example, when it is determined that the main system after switching is in the main state, the main system sends the first data packet through the first port, the backup system sends the first data packet through the second port, the first data packet sent by the main system through the first port is received, and the first data packet sent by the backup system through the second port is discarded; or, when it is determined that the backup system after switching is in the main state, the backup system sends the first data packet through the first port, the main system sends the first data packet through the second port, the first data packet sent by the backup system through the first port is received, and the first data packet sent by the main system through the second port is discarded.

[0082] Specifically, the receiving of the first data packet sent by the main system or the backup system according to the preset downstream packet processing flow rule includes: if it is determined that the main system is in the main state after the switching, the preset downstream packet processing flow rule is used to enable the first port or the second port to receive the first data packet sent by the main system; if it is determined that the backup system is in the main state after the switching, the preset downstream packet processing flow rule is used to enable the first port or the second port to receive the first data packet sent by the backup system.

[0083] When it is determined that the main system is in the main state after the switch, by presetting the downlink packet processing flow rules, the first port corresponding to the main system receives the first data packet sent by the first port, and discards the first data packet sent by the second port corresponding to the backup system; or, the second port corresponding to the main system receives the first data packet sent by the second port, and discards the first data packet sent by the first port corresponding to the backup system.

[0084] When the main system is determined to be in the main state, the second data sent by the preset SWITCH device is forwarded to the main system through the first port or the second port through the preset uplink packet processing flow rule; or, when the backup system is determined to be in the main state, the second data sent by the preset SWITCH device is forwarded to the backup system through the first port or the second port through the preset uplink packet processing flow rule.

[0085] In an embodiment of the present application, a switching process is generated through the process of receiving and sending data packets by the current primary system or backup system, and the priority of the switching process is determined to give priority to the switching process, obtain the preset ACL table to complete the switching process, reduce the processing time of the switching process, and thus avoid the problem of packet loss during the switching process.

[0086] Please refer to Figure 5 , Figure 5A schematic block diagram of a primary-standby high-speed signal circuit switching device provided in an embodiment of the present application.
