The objective of this work is to propose an architectural solution to achieve an efficient, distributed control and management of DiffServ enabled networks. DiffServ offers a scalable QoS provisioning solution but it introduces a certain amount of complexity in terms of management and control. The proposed solution is an alternative to the client/server policy-based approach put forward by the IETF¹, which assumes that complete predefined instrumentation is already implemented in DiffServ nodes. In this work, we suppose that DiffServ nodes offer an API with a minimum number of control functions. Based on this assumption, the proposed solution introduces a new control architecture to configure and control these nodes in a customized and flexible manner.
