Problems solved by technology

In the previous processing method, this time slot adjustment is completed on the cross-connect board, which will not only increase the time-division pressure of the cross-connect board, but also cause service interruption when reconfiguring the time slot, and reduce the flexibility of configuration.

Abstract

A method for regulating the time slot in Virtual Concatenation Group (VCP) includes following steps: separately adding a cross-interaction matrix in the up stream of SDH mapping path and the down stream of de -mapping path to use to make VC time slot regulation; replaces each VC 12 of the VC with Virtual Tributaries (VT). According to the time slot sequence required by VC configures the VC4 bus corresponding to each VT and sequence number of VC4; initializes the cross-interaction matrix; makes the time slot configuration and time slot regulation to VCP. The invention reduces the time division pressure, and also reduces the risk caused by amending time slot algorithm.

Description

technical field [0001] The invention relates to a processing method for a virtual concatenation group time slot of a Synchronous Digital Hierarchy (SDH: Synchronous Digital Hierarchy) optical transmission device. Background technique [0002] In recent years, SDH-based Multi-Service Transport Platform (MSTP: Multi-Service Transport Platform) technology has been widely used in metropolitan area networks. The core idea of ​​this technology is to use VC virtual concatenation to transmit data services. VC refers to a virtual container, which is a technical term in SDH. VC4 and VC12 represent virtual containers of different granularities. VC4 is a 140M virtual container, and VC12 is a 2M virtual container. Because different data services have different bandwidth requirements, for SDH, the service bandwidth carried by each virtual container is limited. For example, VC12 is a 2M virtual container, and VC4 counts a 140M virtual container. However, the bandwidth requirements of act...
