Abstract

In current scenario, network traffic flows need a start-time fair queuing algorithm which is computationally efficient and also which can achieve maximum fairness regardless of variation in a network capacity. To enhance the situation of congestion, an improved round robin (IRR) queue management algorithm for elastic and inelastic traffic flows is proposed. In this approach, the traffic flows are categorised into elastic traffic flows and in-elastic traffic flows. The scheduling process in the inelastic flows is handled by the BRR scheduler algorithm since they have large capacity requirements and delay constraints and elastic flows will be scheduled using DRR-SFF. The results are simulated with NS-2 and they show consistent improvement in the performance of the network.
