Method, device and system for transmitting messages

Abstract

A method for transmitting messages comprises the following steps that: a first Maintenance association End Point (MEP) transmits measurement messages, wherein the measurement message is transmitted from the first MEP to a second MEP through at least one Maintenance association Intermediate Point (MIP); and each of the MIPs receives the measurement message, expands a Type-Length-Value (TLV) in the measurement message, records the measurement data of each MIP in the expanded TLV, and transmits the measurement message. By the method for transmitting messages, the performance data of all nodes on a path can be acquired during a test.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly, to a method, device and system for transmitting messages. Background technique [0002] In OAM (Operation Administration and Maintenance, operation management and maintenance), in order to monitor the performance of the bearer network, in the current technology, ITU-T (TELECOMMUNICATION STANDARDIZATION SECTOR OF INTERNATIONAL TELECOMMUNICATION UNION, International Telecommunication Union Telecommunication Standardization Bureau) Y. 1731 or MPLS-TP (Multi-Protocol Label Switching-Transport Profile, multi-protocol label switching) OAM (based on Y.1731) to achieve, in Y.1731 and MPLS-TP OAM protocol to achieve single-ended packet loss detection, Double-ended packet loss detection, single-ended delay detection, and double-ended delay detection. However, this technology can only realize end-to-end performance monitoring between MEPs (Maintenance association End Points). Th...

[0002] In OAM (Operation Administration and Maintenance, operation management and maintenance), in order to monitor the performance of the bearer network, in the current technology, ITU-T (TELECOMMUNICATION STANDARDIZATION SECTOR OF INTERNATIONAL TELECOMMUNICATION UNION, International Telecommunication Union Telecommunication Standardization Bureau) Y. 1731 or MPLS-TP (Multi-Protocol Label Switching-Transport Profile, multi-protocol label switching) OAM (based on Y.1731) to achieve, in Y.1731 and MPLS-TP OAM protocol to achieve single-ended packet loss detection, Double-ended packet loss detection, single-ended delay detection, and double-ended delay detection. However, this technology can only realize end-to-end performance monitoring between MEPs (Maintenance association End Points). The packets are serious and the delay becomes larger. It is not possible to directly determine which section is degraded.
