Differentiated Services (DiffServ) QoS architecture is scalable but inadequate to deal with network congestion and unable to provide fairness among its traffic aggregates. Recently, IETF has recommended additional functions including admission control and resource discovery to enhance the original DiffServ [1]. In this paper, we propose a comprehensive framework for DiffServ networks. In our new architecture, the Fair Intelligent Congestion Control (FICC) algorithm is applied to provide fairness among traffic aggregates and control congestion inside the networks. The enhanced architecture is realizable within the existing IP network infrastructures. Simulation results show that the FICCDiffServ performs excellently in terms of guaranteed fairness, minimized packet delay and jitter, robust to traffic attributes, and simple to implement. © 2005 IEEE.
