Distributed SSM protocol processing systems and method based on complicated packet switching system

摘要

A distributed SSM protocol processing system and method based on a complex packet switching system, which relate to the technical field of synchronous transmission systems. The system comprises a main control disc, a system switching unit, and at least one service disc. The system switching unit is responsible for communication between a main control processing unit and a service processing unit. The main control disc comprises the main control processing unit and a main control logic processing unit. The main control logic processing unit is responsible for collecting SSM input information of each port of each service disc and encapsulating output data of the main control processing unit. The main control processing unit is responsible for processing the SSM input information. Each service disc comprises a service processing unit and a service logic processing unit. The service processing unit is responsible for calculating SSM output information of each port of the service disc and sending the SSM output information to the service logic processing unit. The service logic processing unit is responsible for reporting the SSM input information of each port of the service disc to the main control logic processing unit and sending an ESMC packet to each port.
