Abstract:

As more and more telecom services carrying over the IP network, the IP MAN needs higher reliability requirements. The service access control layer is the key equipment of converging multi-service in IP MAN, and plays a connecting function in the network. Based on the operational practice and operational testing, the current state of technology of the service access control layer equigment business back up was analyzed. The methods and recommendations with building high reliability service access control layer in the new architecture of bearer network were proposed.

Key words: IP metropolitan area network, service access and control layer, business backup technology, high reliability
