Embodiment Construction

[0027] In order to solve the problem of network robustness, most of the current solutions adopt the form of backup to realize network redundancy. There are also many forms of redundancy. At the beginning, most of them were simple and rude backups. When it comes to master-slave switching backups, no matter which one is a waste of resources, only one is working, and the other is waiting. This is obvious. It is a waste of resources. For example, Layer 2 MLAG and aggregation ports, and Layer 3 VRRP either back up the entire switch or backup ports.

[0028] Network redundancy is a security strategy for industrial networks. As a rapid-response backup system, the purpose of network redundancy is to mitigate the risk of unplanned outages and ensure continuous production through immediate response, thereby reducing the impact of failure at any point on critical data flows.

[0029] Any network that needs to have high reliability or is used in critical occasions requires data channel ...

Abstract

The embodiment of the invention discloses a network redundancy method, device and apparatus. The method comprises the following steps: configuring the same virtual MAC and virtual IP for a plurality of forwarding devices; and configuring a default target of a terminal device as the virtual MAC and the virtual IP through ARP, so that the terminal device redundantly forwards the message to the plurality of forwarding devices to complete message processing. According to one or more embodiments of the present specification, the virtual MAC and the virtual IP of the plurality of forwarding devicesare the same, the terminal device can process the message through any one of the forwarding devices, when a certain forwarding device breaks down, the message processing is not affected, the waiting of a main device or a backup device is avoided while the network redundancy is processed, and the resource consumption is reduced.

Description

technical field [0001] This description relates to the field of communication technology, and in particular to a network redundancy method, device and equipment. Background technique [0002] The robustness of the network often requires attention. A network with poor reliability is relatively weak in coping with network failures. When a network device fails, the network’s ability to carry services will be greatly impacted or even interrupted. In order to solve the problem of network robustness, it is necessary to realize network redundancy in the form of backup. But during backup, only one device can work alone, that is, the backup device can only wait for the main device to be idle before performing backup, or the main device can only continue to work after the backup device is completed. Either way, it is a waste of resources. [0003] In view of the above problems, a better solution is needed to realize network redundancy. Contents of the invention [0004] One or mo...
