Comparative Analysis of Different Queuing Mechanisms in Hetrogeneous Networks (original) (raw)

2013

Abstract

Each router in the network must implement some queuing discipline that governs how packets are buffered while waiting to be transmitted. So Queuing is one of the important mechanisms in traffic management. In this paper various existing queuing algorithms are explained First in First out (FIFO), Priority Queue (PQ), Fair Queue (FQ), Weighted Fair Queue (WFQ), Class based WFQ (CBWFQ), Self Clocked FQ (SCFQ), Worst case fair WFQ (WF 2 Q), Worst Case fair WFQ plus (WF 2 Q+), Round Robin (RR), Weighted RR (WRR), Deficit WRR (DWRR). Then a comparative analysis of three queuing mechanisms FIFO, PQ and WFQ.WFQ technique has a superior quality than the other techniques.
