A service networking architecture for the scalable management of multi-layer networks

Multimedia service users can require multi-services according to their own environment for accessing to public networks. For copying with customer-ori ented service requirements, network providers have to prepare multi-layer s ervice networks. This paper deals with frame relay, ATM and IP networking s ervices on multi-layer networks. In order to provide multiple data services , network provider needs to define and make use of client-server and interw orking relationships between these networks. In this paper, we propose a se rvice management architecture in order to efficiently manage multiple servi ces and network resources from service point of view. The proposed service management architecture includes functionalities such as subscription manag ement, customer-network management, communication session management, and b usiness layer support management. Especially, it describes an information m odel for managing multi-layer networks by way of the interworking or client -server relationship. The proposed functionalities are modeled in accordanc e with the object-oriented modeling concept and implemented on a CORBA plat form. The applications on the proposed architecture include VPN services an d various statistical services for customers and the carrier. The realized system is to be used for Koera Telecom's high speed networks mainly for sup porting Internet services.
