Problems solved by technology

[0004] Regardless of whether it is configured through the command line or the network management, two devices need to be configured independently, and the workload is twice that of a single device. In addition, the configurations of the two devices must be completely consistent, otherwise the business transmission will be blocked, and it will be difficult to troubleshoot the location of the fault.

Embodiment Construction

[0039] Embodiments of the present invention provide a method, device and system for performing service backup among multiple machines, which are used in a multi-machine backup scenario to automatically complete synchronous service configuration between devices. Detailed descriptions are given below respectively. For ease of understanding, in the following embodiments, service configuration between two devices is taken as an example, and service configuration between more than two devices is also applicable.

[0040] It should be noted that, to realize the synchronous service configuration in this embodiment between two devices, it is first necessary to perform corresponding pre-configuration on the two devices, mainly including:

[0041] 1. The same business functions;

[0042] The service functions of the two devices need to be consistent.

[0043] 2. Establish the interface and link configuration of the peer-to-peer topology (Topology) structure with the upstream and downs...

Abstract

Embodiments of the invention disclose an inter-machine business backup method, a device and a system, which are used to perform automatic synchronous configuration among main backup devices under the multi-machine backup background and to carry out business data backup. The method comprises requesting the establishment of a business backup channel with an opposite-end device, wherein the business backup channel is used to transmit the business backup information; and sending the business backup information to the opposite-end device by means of the business backup channel so that the opposite-end device configures according to the business backup information.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for performing service backup among multiple machines. Background technique [0002] In the current broadband remote access server (BRAS, Broadband Remote Access Server) or service router (SR, Service Router) scenario, the reliability of service features is expected to be protected across devices, including broadband access servers (BAS, Broadband Access Server) users, Address Resolution Protocol (ARP, Address Resolution Protocol), Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol) security binding table, etc. If two routers, ROUTER-1 and ROUTER-2, form a master-backup protection relationship, the basic configuration (including routing, interface configuration, and service) on ROUTER-1 and ROUTER-2 is required to be basically the same; the configuration to establish a protection group is Symmetrical; in order to syn...
