N2 - The invention and evolution of the Dense Wavelength Division Multiplexing (DWDM) technology has brought a breakthrough to high-speed networks, and it has put a lot of pressure on research in the area of IP routers to catch up. Besides, with up-coming Quality of Service (QoS) requirements raised by a wide range of communication-intensive, real-time multimedia applications, the next-generation IP routers should be QoS-capable. Limited by the Moore's Law, one possible solution is to introduce parallelism as well as the Differentiated Service (DiffServ) scheme [5,11] into the router architecture to provide QoS provision at a high speed and a low cost. In this paper, we propose a novel architecture called the High-Performance QoS-capable IP Router (HPQR). We address one key design issue in our architecture - the distribution of IP packets to multiple independent routing agents so that the workload at routing agents is balanced and the packet ordering is preserved. We introduce the Enhanced Hash-based Distributing Scheme (EHDS) as the solution. Simulations are carried out to study the effectiveness of EHDS. The results show that EHDS does meet our design goals very well.
