Entry management method and system

Abstract

The invention provides an entry management method and system, which are applied to the technical field of communication. The method comprises the following steps that a primary device distributes entry prefixes to backup devices and synchronizes a plurality of created first entries to the backup devices; the backup devices add the entry prefixes to an index of a first entry; after the primary device and the backup devices are split, the backup device which is upgraded to the primary device creates a second entry and adds the locally-stored entry prefixes into an index of the second entry; and after fault recovery, the primary device obtains all first entries and second entries in the backup devices, merges the first entries and the second entries to a third entry and synchronizes the third entry to the backup devices. The primary device creates the corresponding distribution of the entries and the local storage of the entry prefixes of the first entry and merges all obtained entries in the initial state, so that the integrity and the exclusiveness after merging of the entries are guaranteed, and thus the stability and the accuracy of entry management of the primary and backup devices during network deployment are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular, to a method and system for table item management. Background technique [0002] In the process of network deployment, considering the high reliability of the network, when deploying network devices in key locations, they will be deployed in active and standby mode. When the main device is abnormal, the backup device will be upgraded to the main device to ensure the normal network communication. Table item management in a high-reliability networking environment includes the table item allocation process of multiple original devices in different allocation states. The main process includes: in the initial stage of allocation, the table items of the active and standby devices are synchronized, and the table items are exactly the same. The master and slave split to form two masters. When the entries are assigned to each other again, the index of the entries may be duplic...

AI Technical Summary

Problems solved by technology

If the system is in the entire entry management process, due to business needs, the entries allocated on the two independent master devices in state 2 need to be merged, because if they are not merged, randomly selecting one will cause the entry on the other device to be lost , there is a problem with the business function, but because the two master devices adopt the same principle when allocating entries, the index of the entry may be duplicated, resulting in the conflict of the index of the entry and the problem that it cannot be merged
