TRAFFIC-BASED SCHEDULING MECHANISM IN AN IP/ATM ROUTER

This article briefly presented the design and software architecture of an IP/ATM multiple sub network router. It established the queue model of IP process module and proposed a traffic based scheduling mechanism (AICS: Adaptive Incomplete Cyclic Service). It also provided a simulation study on the system throughput and packet delay jitter performance for both AICS mechanism and IICS mechanism proposed in the prior work. The simulation results show that, comparing with IICS, AICS can provide much better packet delay jitter performance when high speed sub networks exist bursty traffic and give better fairness.
