Embodiment Construction

[0040] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0041] Such as image 3 As shown, in the data network transmission device, the optical port connected between the transmission devices is called a line port, and the interface connected between the transmission device and the client device is called a tributary port.

[0042] The transmission equipment includes the following units: data crossover unit, data line processing unit, data branch processing unit, multiplex section protocol processing unit, and data forwarding table processing unit. The data line processing unit is divided into SDH layer processing module and virtual The container (virtual container, VC) encapsulation and label processing module, and the data branch processing unit are divided into an interface processing module and a label processing module.

[0043] The main function of the data line processing unit is to proc...

Abstract

This invention relates to one method and system to protect label exchange, which comprises the following steps: when there is circuit generation signal affair, inverse station multiple agreement process units inform its fault into other section point and informing station data to list process unit; data transfer list process unit informs needed label process module to fulfill inverse; when multiple agreement is on other station point to inform the data conversion process unit; the said data transfer list unit informs the label module process module.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and system for protecting a label switching path. Background technique [0002] The ITU-T G.841 proposal stipulates the types and characteristics of Synchronous digital hierarchy (SDH) network protection. The proposal specifies the type of SDH network protection and the multiplex section protection protocol. The multiplex section protection protocol uses SDH K bytes in the section overhead, complete SDH network protection, specific protocol details can refer to ITU-T G.841. [0003] Such as figure 1 As shown, the ITU-T G.841 recommendation stipulates that in the SDH network multiplex section protection ring, under normal conditions, a customer circuit goes from point A to point D, and the working path of the multiplex section ring is point A-point B- Point C-Point D. but if figure 2 As shown, when the optical fiber between point B and point C is interrupte...
