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.

Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below.

[0044] The automatic identification method of the near-end CV mode of multi-protocol label switching of the present invention, such as figure 2 and image 3As shown, the message processing system includes at least two layers, a management plane and a data plane. The management plane completes the configuration of the LSP connectivity detection mode, receives the alarm information of the data plane, and feeds back to the user. The data plane completes MPLS message forwarding processing and MPLS OAM&P processing; the MPLS message forwarding processing subsystem recognizes the OAM message, sends the OAM message to the MPLS OAM&P processing subsystem, and completes the LSP protection switching action at the same time. The MPLS OAM&P processing subsystem is responsible for CV mode tracking, CV state machine processing and protection switching processing, etc., which respectively include...

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...
