Abstract

The present invention provides a switching method, device, and SR for a main service router SR and a standby SR. The method is used in a metropolitan area network using a shared gateway. The method includes: according to the configuration mode of the optical line terminal OLT, Detect whether the state of the link between the active SR and the OLT is an available state through a corresponding protocol, wherein, when the OLT adopts a dual uplink configuration, the protocol is the Ethernet connectivity fault management ETH-CFM protocol , when the OLT adopts a single uplink configuration, the protocol is the Link Aggregation Control Protocol LACP; when the state of the link between the active SR and the OLT is unavailable, the active The state is switched to the standby state; the standby SR is notified to switch from the standby state to the active state. By adopting the technical solution provided by the present invention, the switching between the active and standby SRs can be automatically realized according to the link communication state without manual intervention, and the switching efficiency of the active and standby SRs is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for switching between a main service router SR and a backup SR, and the SR. Background technique [0002] According to different access methods, the access layer and aggregation layer of the MAN also correspond to different topological structures. SR (service router, service router) divides the main and standby ports according to different access methods. In the prior art, a cold backup mode is adopted between the active and standby SRs, and when a network element or link of the active segment fails, the active / standby switchover is completed manually. That is, when it is necessary to switch between the active and standby SRs, manual intervention is required, which is inefficient. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a switching method, device and SR for the active serv...
