Policy-based networking architecture for QoS interworking in IP management-scalable architecture for large-scale enterprise-public interoperation

Policy-based networking (PBN) is gaining a wide acceptance in IP management, resulting in a more unified control and management approach toward complexity of IP management. QoS interworking in IP management based on PBN is going to provide QoS guaranteed/differentiated IP connection services. QoS interworking issues between enterprise network and public IP network are studied. The exponential growth of intranet/Internet interworking itself may put PBN in jeopardy. To counter the increasing management complexity, two approaches, policy abstraction and hierarchy organization with precedence rules are proposed and studied.
