Design and Implementation of RCDRR Scheduling Algorithm within Low Speed Networks

QoS is one of the hot points among the network study fields. Currently , because of Low Speed Network (LSN) occupying a very big specific weight among the whole networks, how to provide the real-time services with QoS guarantee for the LSNs customers becomes an important research concern.. In this paper, a scheduling algorithm called Real time Compensation Deficit RoundRobin (RCDRR) according to the LSNs characteristics is proposed to be suitable for realtime packets transmition, and comparing the RCDRR algorithm with DRR algorithm by using the ns2 software. Experiments and simulation results show that RCDRR scheduling algorithm possesses good fairness,low complexity,and can reduce the queuing delay of realtime packets in LSN.
