A Disaster Recovery Method and System for a Distributed Communication Network

Abstract

The invention provides a remote disaster recovery method and a remote disaster recovery system of a distributed communication network, wherein the remote disaster recovery method of the distributed communication network comprises the steps that a core network headquarter device is arranged in the distributed communication network, the core network headquarter device joins in data synchronization with a plurality of regional core network devices in different communication regions and then obtains user data information in the plurality of regional regional core network devices, and when the core network headquarter device determines that any one regional core network device among the plurality of regional regional core network devices is out of order, the core network headquarter device is connected with an access network device in the communication region corresponding to the out-of-order core network device through a second communication link between the core network headquarter device and the access network device and establishes the communication service of the communication region corresponding to the out-of-order core network device. The interruption of communication services due to breakdown or stop of the core network devices is avoided.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a remote disaster recovery method and system for a distributed communication network. Background technique [0002] During the use of communication equipment, planned downtime (such as downtime for equipment upgrades, equipment maintenance or equipment repair, etc.) or sudden downtime (such as due to human error, operation failure, power supply failure or catastrophic event) or in the event of equipment failure. When equipment shutdown or equipment failure occurs, a large amount of communication data will be lost. [0003] The existing technology adopts a method of disaster recovery in a different place, and establishes a communication device in a different place that is the same as the local one, and saves the local communication data in a different place, so as to solve the problem of loss of communication data when the local communication device shuts down...
