Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.
The following describes a software optimization method, a device and an electronic device based on a MAC address forwarding table according to an embodiment of the present application with reference to the accompanying drawings. Aiming at the problem that when the Switch interface is called in the background art, the calling time is overtime, the system is blocked, so that the system operation function and the protection switching function of the ring network are affected, the application provides a software optimization method based on an MAC address forwarding table. Therefore, the problems that when the Switch interface is called, the system is blocked due to overtime calling time, the system operation function and the protection switching function of the ring network are affected are solved, and the two ports belonging to the virtual local area network and used by the Ethernet ring network are bound to each MAC address forwarding table, so that the MAC address forwarding table is effective, and the protection switching function of the ring network is realized.
Specifically, fig. 1 is a schematic flow chart of a software optimization method based on a MAC address forwarding table according to an embodiment of the present application.
As shown in fig. 1, the software optimization method based on the MAC address forwarding table includes the following steps:
in step S101, at least one ring network status of the current vehicle ring network is determined.
Specifically, in the embodiment of the application, the vehicle-mounted ring network mainly comprises three ring networks including a single ring, a double ring and multiple rings, wherein the virtual local area networks used by each ring of the single ring, the double ring and the multiple rings are different, so that the rings do not influence each other when the data flow runs in the respective rings.
Further, as shown in fig. 2, in the embodiment of the present application, a single ring is taken as an example, and in the single ring state, the ring network state in the embodiment of the present application mainly includes at least one of a no-fault state, a single link fault state, and a double link fault state.
In step S102, based on the at least one ring network state, a virtual local area network corresponding to the at least one ring network state and a target physical address of a rotatable port and forwarding data of each switch in the at least one ring network state are determined from a preset MAC address forwarding table.
Further, in one embodiment of the present application, before determining, based on at least one ring network state, a virtual local area network corresponding to the at least one ring network state and a target physical address of a port capable of forwarding data of each switch in the at least one ring network state from a preset MAC address forwarding table, the method further includes: determining a plurality of rotatable ports used when at least one static MAC address forwarding table binds the current vehicle-mounted ring network; determining a target physical address of corresponding forwarding data of each rotatable port according to the plurality of rotatable ports; and obtaining a preset MAC address forwarding table according to the plurality of the rotatable ports and the target physical addresses of the corresponding forwarding data of each rotatable port.
Specifically, the switch a, the switch B and the switch C in the embodiment of the present application each have a plurality of rotatable ports used when the vehicle-mounted ring network is provided, each port corresponds to a target physical address of a target connection device, and the plurality of rotatable ports of each switch and the target physical address of the corresponding forwarding data of each rotatable port are mapped, so as to store the mapped data in a preset MAC address forwarding table.
Further, in the embodiment of the present application, in the obtained preset MAC address forwarding table, a virtual local area network corresponding to at least one ring network state and a rotatable port of each switch and a target physical address for forwarding data in at least one ring network state need to be determined, and since each port of the switch achieves a function of data exchange by identifying a corresponding target physical address, data traffic transmitted by a port of each switch has its own dedicated channel and also has its own target physical address, so that no blocking phenomenon occurs when the data traffic runs on the respective channel regardless of whether it is a single ring, dual ring or multiple ring ethernet.
Specifically, as shown in fig. 2, if the embodiment of the present application is in the non-failure ring network state in the single ring state, when the switch B communicates with the switch C and the lower hanging node device of the switch a, respectively, because the target physical address corresponding to each port of the switch is related to the virtual lan configured at the port, when the virtual lan of the P5 port of the switch B is closed, the static MAC forwarding table of the port is not effective at this time, so the outgoing data traffic can only be transferred from the P7 port of the switch B, and similarly, the data traffic on the switch a can only be transferred from the P5 port of the switch a; when the virtual local area network of the two ports of the switch C is in a completely opened state, outgoing data traffic can be simultaneously transferred out of the two ports respectively, and it is required to be noted that when the outgoing data traffic is transferred out of each port, one more invalid traffic can occupy the switch bandwidth.
Further, when the embodiment of the application is in a single-link fault state in a single-ring state, taking the link 1 fault in fig. 2 as an example, the switch C communicates with the switch B and the switch a down-hanging device respectively, because the P6 port virtual local area network of the switch C is closed, the outgoing data traffic can only be turned out from the P7 port of the switch C, and similarly, the outgoing data traffic on the switch a can only be turned out from the P6 port of the switch; when the virtual local area network of the two ports of the switch B is in a fully-opened state, outgoing data traffic can be simultaneously transferred out of the two ports respectively.
Further, in the case of the dual-link failure state in the single-ring state in the embodiment of the present application, taking the RPL (Remote Initial Program Load, remote start service) link and link 1 failure in fig. 2 as an example, since the RPL link and link 1 have failures, the virtual local area networks of the P5 and P6 ports of the switch a, the P5 port of the switch B, and the P6 port of the switch C are in the closed state, and the outgoing data traffic is intelligently transferred out through the P7 ports of the switch B and the switch C without being affected by the link failure.
In step S103, based on the virtual local area network corresponding to the at least one ring network state, the forwarding action of forwarding data is executed according to the port capable of being turned out and the target physical address of forwarding data, so as to optimize the ring network switching function of the current vehicle ring network.
Specifically, the embodiment of the application forwards the data traffic of each port channel to the corresponding target physical address based on the virtual local area network state corresponding to each switch port in at least one ring network state and the target physical address corresponding to each port so as to optimize the ring network switching function of the current vehicle-mounted ring network, and meanwhile, if the MAC address forwarding table discovers a new switch port, the target physical address of the new port can be learned and stored so as to improve the operation performance of the vehicle-mounted ring network system.
Further, in an embodiment of the present application, the software optimization method based on the MAC address forwarding table further includes: when the virtual local area network binds a plurality of rotatable ports, the time consumption of each scheduling period is calculated according to the calling times set by each scheduling period.
Specifically, in the embodiment of the application, a plurality of rotatable ports are bound in the virtual local area network of each switch, and in the scene of ring network protection switching function and recovery switching, a EthSwt _Enable Vlan interface or a AutoSar standard interface is required to be called to realize data information transmission of each port.
For example, taking the example of calling the switch a port, the embodiment of the present application uses a scheduling period of 10ms, and each period needs to call the EthSwt _enable Vlan interface 2 times, and at this time, the switch a port needs to process three periods, so that the time consumption of each scheduling period is 3×10ms+20-30 ms=50-60 ms, and at the same time, one processing period is increased every virtual local area network is added.
Further, in an embodiment of the present application, the software optimization method based on the MAC address forwarding table further includes: identifying a current mode of each switch within the at least one ring network state; if the current mode is the dynamic learning mode, the dynamic learning mode of each switch is closed.
Specifically, when the embodiment of the application is used for transmitting data traffic, the current operation mode of each switch in at least one ring network state needs to be identified, and if the current mode of each switch is a dynamic learning mode, unknown unicast data traffic can be flooded to all devices of an invalid link at the moment, so that the dynamic learning mode of each switch needs to be closed in order to ensure the stability of a communication system.
According to the software optimization method based on the MAC address forwarding table, based on at least one ring network state of the current vehicle-mounted ring network, a virtual local area network corresponding to the at least one ring network state and a target physical address of a rotatable port of each switch and forwarding data in the at least one ring network state are determined from a preset MAC address forwarding table, and forwarding actions of forwarding data are further executed, so that ring network switching functions of the current vehicle-mounted ring network are optimized. Therefore, the problems that when the Switch interface is called, the system is blocked due to overtime calling time, the system operation function and the protection switching function of the ring network are affected are solved, and the two ports belonging to the virtual local area network and used by the Ethernet ring network are bound to each MAC address forwarding table, so that the MAC address forwarding table is effective, and the protection switching function of the ring network is realized.
