Abstract

The invention provides a pseudo wire protection method and device. The method includes the following steps: determining the state anomaly of any pseudo wire except a first pseudo wire in a ring service network, wherein the pseudo wires in the ring service network form a loop, the first pseudo wire is a pseudo wire through which a message received by a master node passes for the last time, and thefirst pseudo wire is used to constitute a pseudo wire load sharing path for data forwarding; and enabling a data forwarding function of the first pseudo wire. According to the scheme of the invention,the problems that dual steams exist in part of links in the case of network failure and the waste of bandwidth is caused in related technologies can be solved, and the bandwidth can be saved.

Description

technical field [0001] The invention relates to the field of data network communication, in particular to a pseudowire protection method and device. Background technique [0002] Driven by the trend of IP-based telecommunication services, Multi-protocol Label Switching (MPLS for short) is the most important technology in today's packet switching network. At present, it has been developed from point-to-point to point-to-multipoint, and this technology is commonly used in carrier-class networks. For such a complex network, it is inevitable to introduce a relatively powerful protection technology. In the dynamic and static technology of MPLS, a powerful link detection protocol (OAM for short) and a bidirectional forwarding detection (Bidirectional Forwarding Detection, BFD for short) are respectively used. function to protect the network. [0003] In the MPLS network, there are many protection schemes at present, and the representative ones are: Fast Reroute (FRR) bypass prot...
