Problems solved by technology

[0009] In view of this, the present application provides a method and device for realizing disaster recovery and backup, which is used to solve the problem that the active and standby vBRAS-CP devices are switched even if the service is switched due to the high priority level of the route of the original active vBRAS-CP device in the prior art. Afterwards, service packets still arrive at the original active vBRAS-CP device, which interrupts user services.

Abstract

The present application provides a method and device for implementing disaster recovery and backup. The method is applied to the first vBRAS-CP device. The method includes: receiving a user service message, where the user service message includes a destination IP address; when the When the destination IP address is the group IP address of the vBRAS-CP device group, and after the switchover of the active and standby vBRAS-CP devices for disaster recovery occurs, the user service packet is encapsulated, and the Tunnel between, and send the encapsulated user service message to the second vBRAS-CP device, so that after the second vBRAS-CP device decapsulates the encapsulated user service message, obtains and User service packets are processed.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and apparatus for implementing disaster recovery backup. Background technique [0002] With the expansion of enterprise scale, the single-machine backup of user data can no longer meet the needs of critical business for system availability, real-time, and security. Backup data is often destroyed due to various factors, such as earthquakes, fires, loss and so on. The emergence of remote disaster recovery solutions can further improve the disaster recovery capability of data against various security factors by establishing backup systems in different locations. [0003] For broadband remote access server (English: Broadband Remote Access Server, referred to as: BRAS) forwarding control separation system, the control plane of BRAS (English: Control Plane, referred to as: CP), that is, the virtual broadband remote access server that realizes the func...
