DiffServ Supporting Scheduling Algorithm for CICQ
Yunfei Guo · Jisuanji gongcheng · 2007
Buffered crossbar switches are becoming more and more attractive to high performance routers/switches builders than other schemes,as it can achieve throughput,rate and delay guarantees,and distributing scheduling algorithm can be easily implemented.This paper proposes a distributed scheduling algorithm(shorted by DS) supporting differentiated service model(DiffServ) for CICQ switches,which has lower time complexities than previous algorithms.It evaluates the performances of DS through simulation under burst uniform and non-uniform traffic,and compares it with previous algorithms.Simulation results show that DS can provide minimum bandwidth guarantees for EF and AF traffic and fair bandwidth allocation for BE traffic.
