Simulation Based Performance Evaluation of Queueing Disciplines for Multi-Class Traffic
Saptarshi Ray · IOSR Journal of Computer Engineering · 2012
Queuing is one of the very vital mechanisms in traffic management system.Each router in the network must implement some queuing discipline that governs how packets are buffered while waiting to be transmitted.Several queue scheduling disciplines have been designed to improve the quality of service and to avoid congestion for networked multimedia applications.In this paper, we evaluate the performance of four queueing disciplines (FIFO, PQ, WFQ and DWRR) that are widely deployed for multi-class traffic and analyze their performance using OPNET simulator and compare their relative performance based on queueing delay, packet received, packet drop rate, end-to-end delay and delay jitter with RED and WRED policies.
