Rapid cutover method based on circuit configuration pair

Abstract

The invention discloses a rapid cutover method based on a circuit configuration pair. The method comprising the steps of building a cutover task, building cutover pairs in the cutover task, assigning a circuit before cutover for each cutover pair, and building a corresponding circuit after cutover; forming network elements of the cutover pairs into the circuit configuration pair one by one, and setting the attribute of the circuit configuration pair, wherein the circuit configuration pair comprises configuration before cutover and configuration after cutover corresponding to the circuits before and after cutover; configuring each network element in the circuit configuration pair to a network element configuration library, performing incremental isolation on the configuration before cutover and the new configuration after cutover according to the configuration attribute in the circuit configuration pair by using the network element; executing a cutover task, and starting the circuit configuration pair so as to make the configuration before cutover be invalid, and bring the configuration after cutover into effect; after the cutover is successful, deleting the configuration before cutover in the circuit configuration pair. According to the method provided by the invention, service life of the original circuit is improved, switching time of the circuit is reduced, and uninterrupted cutover of the circuit is achieved, and a cutover risk is reduced,

Description

technical field

[0001] The invention relates to circuit cutover in transmission network end-to-end network maintenance, in particular to a fast cutover method based on circuit configuration pairs. Background technique

[0002] In the transmission network, due to the increasing network scale, more and more equipment types, and more and more complex topological connections, the circuit cutover operation due to network adjustment and network expansion is becoming more and more complicated, and the execution time is getting shorter. The longer and longer the network circuit interruption time, the higher and higher the risk will eventually be, requiring a lot of manpower for network protection, making the efficiency of network cutover lower; it can be seen that there is an urgent need for a fast, low-risk , The cutover scheme with short circuit interruption time solves this very difficult problem in network management.
