Problems solved by technology

[0011] However, the current fault management and performance management of OAM are end-to-end, and it is impossible to effectively monitor the intermediate nodes passing through the station. Once the service is lost or interrupted, it is often necessary to individually check the nodes that are not on the service path one by one. Increased maintenance costs for network management

Embodiment Construction

[0045]Term explanation:

[0046]LB: Loopback, loopback.

[0047]LBM: Loopbackmessage, loopback message.

[0048]LBR: Loopback reply, loopback reply.

[0049]TLV: type-length-value format.

[0050]The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0051]The embodiment of the present invention provides an LB detection method based on MPLS-TP OAM, which includes the following steps:

[0052]In the test process, the Traceroute method is adopted, that is, starting from the nearest passing node of the source node, start the LB test station by station until the sink node; and calculate the delay and packet loss rate of each node during the LB test;

[0053]Analyze the results of the LB test of each node and report it to the main control to confirm the location of the failure point.

[0054]The embodiment of the present invention extends the LB detection in the MPLS-TP OAM, realizes the delay and packet loss measurement under the LB detect...

Abstract

The invention discloses an LB detection method and system based on MPLS-TP OAM, relates to the technical field of communication, and aims to expand LB detection in MPLSTP OAM, realize time delay and packet loss measurement under LB detection and improve the detection efficiency. And the station-by-station measurement time delay and packet loss measurement of the station-passing node are realized,and the defects that only end-to-end measurement can be realized and the station-by-station measurement of the station-passing node cannot be realized in the existing LM / DM measurement technology areovercome. And meanwhile, a station-by-station detection function of LB similar to Trace is realized, and rapid fault positioning of engineering operation and maintenance is facilitated.

Description

Technical field[0001]The present invention relates to the field of communication technology, in particular to an LB detection method and system based on MPLS-TP OAM.Background technique[0002]According to the actual needs of operators' network operations, network management work is usually divided into three categories: Operation, Administration, Maintenance, or OAM for short. It mainly completes the analysis, prediction, planning and configuration of daily network and business; maintenance is mainly the daily operation activities of network and business testing and fault management.[0003]MPLS-TP OAM is MPLS-TP (Multi-Protocol Label Switching Transport Profile, multi-protocol label switching transport application), which implements hierarchical management and control of the original OAM, such as section layer, tunnel layer, pseudo wire layer, service layer and access Link layer. MPLS-TP OAM will perform hierarchical OAM for these layers respectively.[0004]The main functions of OAM ca...
