Automatic identifying method for near-end CV mode of multi-protocol tag exchange

Abstract

A method for automatically identifying near end CV mode of multiprotocol countermark interchange includes setting CV mode at far end of countermark interchange path by management plane, setting track mode at near end of countermark interchange path by management plane, tracking and holding consistency to far end CV mode by near end of countermark interchange path according to CV mode message.

Description

technical field [0001] The invention relates to a multi-protocol label switching technology in an optical network, in particular to an automatic identification method for near-end connectivity check (CV) mode in multi-protocol label switching operation and maintenance (MPLS OAM). Background technique [0002] Multi-Protocol Label Switching (hereinafter referred to as MPLS) technology introduces the idea of ​​ATM fixed-length label switching, which makes the data plane of the traditional IP network transition from "connectionless" to "connected" and realizes "telecom Class" next-generation network; at present, the control plane of the MPLS network is still connectionless, while the introduction of QoS (Quality of Service), TE (Traffic Engineering), virtual private (dedicated) network VPN (Virtual Private Network) , OAM (Operations and Maintenance) and other technologies, MPLS has gradually become a key technology for triple play integration. [0003] ITU-T defines the MPLS O...

Problems solved by technology

However, if the near-end and remote configurations are different, services will fail; especially when R1 and R2 are managed by different network managers, for example, R1 and R2 may be equipment of different operators, and the configurations of the near-end and remote occur

[0015] And obviously, this mode needs to be configured twice at the near-end and far-end of the LSP, and the configuration workload is relatively large.
