Embodiment Construction

[0024] specific implementation plan

[0025] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and detailed descriptions of known functions or configurations included herein or shown in the accompanying drawings are omitted to avoid unnecessarily obscuring the subject matter of the present invention. describe.

[0026] In view of the fact that there are many OAM functions in the network, but the operations of the nodes on the OAM are basically similar, we take the CV packet as an example to describe the present invention.

[0027] figure 1 It is a scenario for the application of the present invention. The MPLS and T-MPLS networks are peer-to-peer networks, and the two networks are interconnected through their own edge nodes. These two edge nodes can be regarded as gateway nodes and perform corresponding processing on OAM.

[0028] According to the principle of network interconnection, based on the c...

Abstract

The present invention provides a method for OAM function intercommunication in network interconnection. The method is used for realizing uniform OAM function when a MPLS network and a T-MPLS network form peer-to-peer interconnection. The method of the invention expands the processing to the OAM frame for completing the processing of OAM frames between different networks. At the same time the mapping of different network OAM frame format is completed between the network boundary nodes for realizing the same OAM function of different networks. The method according to the invention effectively uses the extensibility of OAM frame and the extensibility of node to the OAM frame processing. The intercommunication of OAM function is realized when the MPLS and T-MPLS network are interconnected. The realizing of OAM function of two networks is guaranteed. The operation managing capacity when the networks are interconnected is increased.

Description

[0001] Field [0002] The present invention generally relates to the realization mechanism of network intercommunication, and more specifically relates to the processing mechanism of OAM intercommunication between T-MPLS packet transport network and MPLS network. Background technique [0003] T-MPLS is a transport technology that simplifies MPLS to meet the needs of the transport network. Its core is to establish an end-to-end Label Switching Path (LSP) through the network management system or control plane. Packet services are forwarded based on labels on the LSP. T-MPLS simultaneously supports bandwidth statistical multiplexing of packet services and deterministic transmission of TDM services. TMPLS technology simplifies and develops MPLS, and cuts down the elements of MPLS technology according to the requirements of the transport network. For example, it does not support optional items in MPLS such as PHP, aggregation, and ECMP, but expands the OAM, protection, and intelli...
