Abstract

The invention discloses a PW dual-homing protection switching method, comprising: establishing a primary PW between the first node and the second node, establishing a standby PW between the first node and the third node; establishing a PW between the RNC server and the second node The main access link is to establish a standby access link between the RNC server and the third node, and to establish the first auxiliary PW and the second auxiliary PW between the second node and the third node; when the main PW fails, the The traffic sent by the RNC server is switched from the main PW forwarding to the first auxiliary PW forwarding; and / or when the main access link fails, the traffic sent by the RNC server is switched from the main access link forwarding to the standby access link forwarding , and switch forwarding from the standby PW to forwarding by the second auxiliary PW. The invention also discloses a PW dual-homing protection switching system. The scheme of the present invention realizes the reasonable and effective forwarding of traffic, saves the flow of traffic forwarding, and improves the efficiency of traffic forwarding and protection.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a PW dual-homing protection switching method and system. Background technique [0002] With the continuous development of mobile communication technology, more and more mobile terminals have entered people's daily life and work. In order to ensure the normal communication of the mobile terminal, it is necessary to deploy protection links to the links of each node in the mobile communication network. A PW (pseudo-wire, pseudo-wire) dual-homing protection group is a common networking in a mobile backhaul network. refer to figure 1 , is a schematic diagram of a dual-homing protection embodiment in the prior art. PE1 (node ​​1) and PE2 (node ​​2) are deployed as dual-homing nodes relative to an RNC (Radio Network Controller, radio network controller) server, providing dual-homing protection from PE3 (node ​​3) to the RNC server. By deploying BFD (Bidirectional Forwar...
