Traffic-based scheduling mechanism and performance analysis in IP/ATM router

We briefly present the design and software architecture of an IP/ATM multiple sub-network router. We establish the queue model of the IP process module and propose a traffic-based scheduling mechanism (AICS, adaptive incomplete cyclic service), on the basis of our prior work. We also provide a simulation study on the system throughput and packet delay jitter performance for both the AICS mechanism and IICS mechanism proposed in prior work. Simulation results show that, compared with IICS, AICS can provide much better packet delay jitter performance when high-speed sub-networks exist with bursty traffic and gives better fairness
