Analysis and Simulation of Weighted Random Early Detection ( WRED ) Queues

This project examines the effects of weighted random early detection (WRED) packet discard on dropping probabilities for multi-class traffic. The flexibility of the WRED parameters will be illustrated with respect to performance parameters and traffic characteristics. Recent advances in analytic RED modeling will be described and extended to WRED and analytic results compared to those found using the simulation model developed for this project. Guidelines for setting WRED parameters will also be examined for various traffic scenarios.
