Technical Field

The invention relates to the technical field of network communication, in particular to a mutual backup method and a mutual backup device of links based on a dual-optical dual-network link.

Background

In communication engineering, redundancy refers to artificially repeating configuration of some key components or functions for the sake of system safety and reliability. When a system fails, for example, a certain device is damaged, the redundantly configured components can be used as a backup to timely intervene and undertake the work of the failed components, thereby reducing the failure time of the system. Redundancy is particularly useful for emergency handling. Redundancy may exist at different levels, such as network redundancy, server redundancy, disk redundancy, data redundancy, and the like.

In the process of multimedia data transmission, signal redundancy backup is an important means for ensuring the safe, stable and uninterrupted operation of a system, so that the adoption of a backup technology with high efficiency and low cost is more and more important. The traditional signal backup method is to use network link backup, set two network links, set one of them as the main link, and the other one as the backup link. When the active link fails, the standby link is automatically switched to.

In the process, the state of the main link needs to be detected in real time, when the main link is used, the standby link is not started, because each link needs to be configured with different IP addresses and MAC addresses, when the two links are switched, corresponding routing and other entries also need to be updated, the complexity of operation is high, the time spent on switching the links is long, the interruption of multimedia transmission is possibly caused, and meanwhile, when some accidents occur, all links of the same type easily break down, and the requirement cannot be met only by adopting network link backup.
