Method and system for processing OAM (operation, administration and maintenance) detecting results in MPLS-TP (multiple protocol label switching-transmission parameter) network

Abstract

The invention provides a method a system for processing OAM (operation, administration and maintenance) detecting results in an MPLS-TP (multiple protocol label switching-transmission parameter) network. The method includes following steps: receiving CCM (confidential code message); processing the CCM to obtain a processing result; judging whether the processing result has errors or not, if yes, entering a subsequent step, namely processing, and if not, stopping processing; judging whether the error type needs to copy the message to be sent a CPU (central processing unit) or not, if yes, sending the message, and if not, stopping processing; judging whether the error type needs to be recorded in an ErrorCache and reported the errors through the ErrorCache or not, if yes, performing ErrorCache processing, and if not, stopping processing; and judging whether the error type needs to report the errors by sending quick switching information, if yes, marking the errors with needs to send the quick switching information, and if not, stopping processing. Consequently, one or multiple error informing mechanisms can be provided flexibly and diversely aiming at different error types to meet requirements of the system.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for processing OAM detection results in an MPLS-TP network. Background technique [0002] MPLS-TP was proposed by the joint working group established by ITU-T and IETF in April 2008. Its predecessor was the T-MPLS technical standard developed by ITU-T in May 2005. IETF will absorb OAM (Operations, Administration and Maintenance), protection and management transmission technologies in T-MPLS, and expand the existing MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) to MPLS-TP (Transport Profile for MPLS) , to enhance its support for ITU-T transmission requirements. [0003] One of the differences between MPLS-TP and MPLS technology is that it has a carrier-class OAM function. The main function of MPLS-TP OAM is to monitor services such as Section, LSP, and PW, and data channels, locate faults, and report errors. [0004] In ...

AI Technical Summary

Problems solved by technology

However, the current OAM detection result processing functions are relatively single, which cannot process different detection results, and cannot provide richer usage methods for the upper-layer system for application requirements such as error reporting and protection switching.
