Problems solved by technology

However, according to the existing technology, the detection messages in the two formats correspond to different packet sending processes, which cannot be sent uniformly, thus consuming a lot of system resources and increasing the complexity of system processing

Embodiment Construction

[0029] The embodiment of the present invention provides a message sending method and device, which are used to send a CFM message and an MPLS-TP OAM message through the same message in a unified manner.

[0030] The technical solutions provided by the embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0031] see figure 1 , a message sending device provided by an embodiment of the present invention, comprising:

[0032] The CFM message assembly module 101 is configured to generate and encapsulate a connectivity fault management CFM message according to a preset period;

[0033] The CFM message parsing module 102 is used for analyzing the CFM message encapsulated by the CFM message assembling module 101, judging whether the CFM message needs to be reorganized according to MPLS-TP, and when MPLS-TP reorganization is required, determine the reorganization The following CFM packets need to detect tunnels or pseudowire PWs...

Abstract

The invention discloses a message sending method and device, which are used for uniformly sending a CFM (Connectivity Fault Management) message and a MPLS-TPOAM (Multi-Protocol Label Switching-Transport Profile Operation, Administration and Maintenance) message through the same message. The message sending method provided by the invention comprises the following steps: a CFM message assembling module generates and encapsulates the CFM message at a preset period; a CFM message parsing module parses the CFM message encapsulated by the CFM message assembling module, judges whether the CFM message needs to be reassembled according to a multi-protocol label switching-transport profile (MPLS-TP) and determines that the reassembled CFM message needs to detect a channel or a pseudo wire (PW) when MPLS-TP reassembly is needed; when the CFM message needs MPLS-TP reassembling, a message reassembling module encapsulates the CFM message once again; and the message sending module sends the encapsulated CFM message or the MPLS-TPOAM message.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a message sending method and device. Background technique [0002] Operation management and maintenance (OAM, Operation, Administration and Maintenance), which can realize real-time monitoring of links, fault handling, configuration management, performance management, etc. [0003] Y.1731 is a proposal proposed by the International Telecommunication Union Telecommunication Standardization Organization (ITU-T), which provides an implementation standard of Ethernet OAM. [0004] Connectivity Fault Management (CFM, Connectivity Fault Management) is a Layer 2 Ethernet OAM protocol defined by the Institute of Electrical and Electronics Engineers (IEEE), which supports the OAM standard defined by ITUT-T (the current version supports Y.1731 ). The following introduces several concepts in CFM. [0005] Maintenance Domains (MD, Maintenance Domains): each maintenance do...
