System hot standby processing method, management board and communication equipment

Abstract

The invention provides a system hot standby processing method, a management board and communication equipment. The method comprises the following steps that a slave management board maintains and processes a self state abstract content generated according to the self state and the acquired state abstract content of a main management board; the slave management board judges whether the self state abstract content is consistent with the acquired state abstract content of the main management board or not according to preset trigger conditions; and the slave management board synchronizes the selfstate with the state of the main management board when the self state abstract content is inconsistent with the acquired state abstract content of the main management board. The management board comprises a maintenance module, a judgment module and a synchronization module. The communication equipment comprises the main management board and the slave management board, wherein the slave managementboard comprises the management board. The embodiment reduces the communication among boards in the hot standby process to maximum extent, increases the success rate for switching and has higher efficiency.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a system hot standby processing method, a management board and communication equipment. Background technique [0002] In the field of data communication, the main products include routers and switches. Due to the large number of data packets in the backbone network, both routers and switches may fail. Among them, the core router or switch is often configured with redundant hardware and software resources, and can be switched to the corresponding backup resource when the main router or switch fails. However, most current products need to restart the routing control process on the backup resource after switching, such as Border Gateway Protocol (Border Gateway Protocol; hereinafter referred to as: BGP), shortest path first (Open Short Path First; hereinafter referred to as: OSPF) ), protocol-independent multicast routing protocols, etc., re-establish connections with n...
