ASYNCHRONOUS TRANSFER MODE NETWORKING CONTROLLER AND COMMUNICATION NETWORK SYSTEM

摘要

An asynchronous transfer mode networking controller includes: a plurality of exterior interfaces connected to a plurality of networking controller, and an interior interface connected to the local asynchronous transfer mode switching model, yet includes: an interface processing model, used for processing network transmission service and implementing the uplink and downlink transmission of the local service and transparently transmission of the non-local service; an operation management processing model, used for implementing automatic topo management and data configure synchronization by operating and managing signal element; a switch schedule processing model, used for implementing the schedule and quality of service ensure of the interlink service between the networks; a route selecting or a protection switching model, used for implementing path switching, implementing the automatic reset of the service on the network, examining the fault of the asynchronous transfer mode layer or transmission layer and implementing corresponding protection switching. The invention discloses a communication network system of asynchronous transfer mode. The invention can implement various networking method, facilitate network maintenance, and can ensure the efficiency and credibility of the network.
