SDH multi-group multi-member fiber-crossing virtual concatenation implementation method, device and system

Abstract

The invention provides an SDH multi-group multi-member fiber-crossing virtual concatenation implementation method, device and system, so as to reduce the implementation cost of SDH multi-group multi-member fiber-crossing virtual concatenation. The method comprises the steps: enabling the second interfaces of all cross connectors with first and second interfaces to be connected in an end-to-end manner to form a channel ring; selecting any one cross connector from the cross connectors with first and second interfaces as flow analysis equipment; transmitting the flow of first interfaces of other cross connectors except the flow analysis equipment to the corresponding second interfaces through internal cross modules. According to the technical scheme of the invention, the method can achieve the series connection of any cross connector, and achieves the aggregation and analysis of a lot of fiber-crossing virtual concatenation members. Moreover, the method can quickly recover the stability of a line. In addition, the method enables the fault probability of rear-end equipment of the whole system cluster to be changed into P*1 from P*N, can achieve the SDH multi-group multi-member fiber-crossing virtual concatenation under the condition that there is no MSTP equipment, and reduces the implementation cost.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method, device and system for realizing SDH multi-group multi-member cross-fiber concatenation. Background technique [0002] The synchronous digital hierarchy (Synchronous Digital Hierarchy, SDH) protocol is a transmission protocol widely used in data transmission at present. SDH lines can simply complete the conversion between low-speed lines and high-speed lines through time-division multiplexing and demultiplexing technologies. As a transmission protocol, SDH lines can carry various data services at the same time, such as telephone data services, computer data services, POS, GFP, ATM, TUG and WAN services. [0003] The Generic Framing Procedure (GFP) belongs to the ITU-T G.7041 specification and is a new encapsulation procedure. In MSTP, in addition to the traditional point-to-point protocol / high-speed data link protocol (PPP / HDLC), link access procedure (LAPS) on...

Problems solved by technology

[0006] The above-mentioned existing solutions require the use of expensive MSTP equipment, which makes the implementation of SDH multi-group multi-member cross-fiber cascading very costly. After the network environment of the front-end operator changes, the MSTP equipment also needs to be reconfigured. However, the configuration MSTP equipment is an extremely complicated process, which not only has high labor costs, but also is prone to errors
