Customer Management and Control of Broadband VPN Services

We present an architecture for customer management and control of a broadband VPN service. The architecture is aimed at giving the VPN customer a high level of control over the traffic on the VPN, such that end-to-end requirements for the customer’s enterprise network can be met. We describe how different control and management objectives can be achieved with this architecture. Its design includes a generic resource controller, which can be specialized in order to realize a large class of control schemes, following a customer’s specific requirements. We have implemented a prototype of this architecture on a high-performance emulation platform. The prototype allows us to validate the management and control functionality of the customer control system and to demonstrate the performance characteristics of different realizations of the architecture.
