Abstract

The invention discloses an operation, administration and maintenance (OAM) message processing method and an OAM message processing device. The method comprises the following steps of: resolving a received message, determining the message is an OAM message, and acquiring the encapsulation information of a connectivity fault management (CFM) message corresponding to the OAM message; and restructuring the OAM message according to the encapsulation information into the CFM message. By the technical scheme provided by the invention, the reception of tunnel-and-pseudo-wire-related OAM message in a multi-protocol label switching-transport profile (MPLS-TP) is realized, the consumption of system resources is reduced, and the system processing complexity is reduced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for processing an Operation, Administration and Maintenance (OAM) message. Background technique [0002] Connectivity Fault Management (CFM for short) is a Layer 2 Ethernet OAM protocol defined by the Institute of Electrical and Electronics Engineers (IEEE for short), which supports ITU telecommunication In the OAM standard defined by the standardization organization (ITU-T for ITU Telecommunication Standardization Sector, referred to as ITU-T), the CFM message is a layer 2 Ethernet packet, and the characteristic is that the Ethernet type number is 0x8902. On the forwarding chip at the receiving end, if the Ethernet type of a message is resolved to be 0x8902, the message will be processed by the CFM message. Since the CFM supports the OAM standard defined by the ITU-T, the content of the Protocol Data Unit (Protocol Data Unit, PDU) of the CFM messa...
