Problems solved by technology

[0004] However, the NSR technology is applicable to the situation where the main management board fails and the data plane remains unchanged in the redundant system with dual management boards; while in the VSU system, when the main device fails, if the forwarding path also changes, the original Data plane forwarding will lead to long-term disconnection

Abstract

The embodiment of the invention provides a protocol state backup method and device, electronic equipment and a storage medium. The method comprises the following steps: pre-calculating corresponding protocol states when main equipment and standby equipment in the VSU system are respectively used as forwarding equipment, and storing all pre-calculated protocol states in the standby equipment; if itis detected that the main equipment breaks down, taking the standby equipment as new main equipment, and determining the standby protocol state according to the protocol state pre-stored in the new main equipment; and forwarding a message through the new primary device according to the standby protocol state. According to the protocol state backup method provided by the embodiment of the invention, the multiple protocol states are backed up in advance, and when the main equipment is switched, the proper protocol state is selected according to different conditions, so the problem of long-timecutoff of the system caused by protocol state recalculation when the main equipment is reset is avoided, and the system performance is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a protocol state backup method, device, electronic equipment, and storage medium. Background technique [0002] The VSU (Virtual Switching Unit) system is a network system virtualization technology that supports virtualization of multiple devices into a single virtual device, thereby simplifying the network topology, reducing network complexity, shortening the time for application recovery and service interruption, and improving Utilization of network resources. Since multiple devices in the VSU system act as a network entity, they need to share control information and some data flows. The special link for transmitting control information and data flow between devices in the VSU system is called a virtual switching link (Virtual Switching Link, VSL). [0003] In the existing VSU system, protocol backup is mainly nonstop routing (Nonstop Rout...
