Abstract

The invention provides a switching system in the communication network and a method thereof. The system comprises a configuration information providing module which is used for statically producing the TDM configuration information at the output port of every byte for indicating TDM frame payload; and the grouping message configuration information at the output port of every byte for indicating grouping message is generated according to the service type information at the input port of the switching system and the information at the output port of the grouping message; and the TDM frame configuration information and the grouping message configuration information are transmitted by the configuration information providing module; the system also comprises a configuration module which is used for implementing switching control according to the received TDM frame configuration information and the received grouping message configuration information, and a switching matrix module which is used for receiving the TDM frame configuration information or the grouping message and implementing switching of the TDM frame payload or the grouping message in the unit of byte under the control of the configuration module. The system and method provided by the invention can better support the evolution from TDM to full IP pattern.

Description

technical field [0001] The invention relates to the field of switching technology, in particular to a switching system and method in a communication network. Background technique [0002] At present, the service bearer network of telecom operators is facing the evolution from the traditional Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) network to an all-IP packet network, but in the process, Time Division Multiplexing (TDM, Time Division Multiplexed) It will coexist with the packet network transmitted by packet message for a rather long period of time. How to make the TDM service and the packet message service coexist, there are the following two mainstream equipment solutions in the industry. [0003] Option 1: Adopt multi-service transmission platform (MSTP, Multi-Service Transmission Platform) equipment developed from SDH equipment, and the switching network of MSTP equipment uses TDM as the core processing structure. The MSTP device encapsulates t...
