Abstract

Abstract:

Queue management functions are responsible for router’s queue establishment, maintenance and line up and determine when to accept or discard packets. Active queue management algorithm DropTail is widely used for congestion control in Internet. Random Early Detection (RED) is recommendedly used by IETF for queue management. The article uses the NS2 network simulator to simulate DropTail and RED queue management algorithm. Through analysis of the simulation data, the obtained RED queue management algorithm is higher than the overall performance of DropTail. This study provides the basis for further research of the RED algorithm.

Key words: network congestion, DropTail, RED, network simulation
