Abstract

The invention relates to a method for realizing multi-protocol label switching bidirectional protection switching. The method mainly includes: first, in an MPLS (multiprotocol label switching) network, configure corresponding bidirectional protection switching policy information for a bidirectional LSP (label switching path) based on an APS (automatic protection switching) protocol; then, when in the MPLS network based on When the APS protocol determines that bidirectional protection switching is required, the bidirectional protection switching operation is performed according to the configured bidirectional protection switching policy information. Therefore, the present invention can realize effective protection to MPLS LSP two-way data channel, guarantees that the time delay of two-way flow is in equal; Simultaneously, the APS agreement that the present invention introduces can cover the protection of MPLS LSP one-way data channel, thereby unified one-way and The realization of the mechanism of two-way protection.

Description

technical field

[0001] The invention relates to the technical field of network communication, in particular to a method for realizing multi-protocol label switching bidirectional protection switching. Background technique

[0002] With the development of network technology, Ethernet services gradually develop from local area network to metropolitan area network and telecommunication network. In the ever-increasing demand for next-generation Ethernet services, MPLS (Multiprotocol Label Switching) technology has become the preferred network technology relying on its unique advantages. Its advantages are mainly manifested in: fast recovery, network scalability, Qos (Quality of Service) business capabilities, business aggregation capabilities, and business interoperability capabilities, and so on.

[0003] As MPLS technology becomes the key technology for IP network multi-service bearer, MPLS fault detection and protection switching has become an important subject of concern in...
