Abstract

Nowadays with the addition of application demands, the quality of service (QoS) of network becomes more and more important. Network QoS has a variety of support mechanism, this paper mainly studies two congestion avoidance mechanisms: Random Early Detection (RED) and weighted RED (WRED). Using OPNET software to create network simulation models with three different scenarios. Each scenario support different QoS guarantee mechanism,here, the Scenario 1 has no QoS guarantee, the Scenario 2 supports RED mechanism and the Scenario 3 supports WRED mechanism. Do simulation experiments ten minutes, and verify the validity and importance of RED and WRED these two kinds of mechanisms in terms of providing QoS guarantee by analyzing the simulation results of three scenarios. And through comparing the statistical results between Scenario 2 and Scenario 3, we realized that RED provides the same level QoS for different types of traffic, however WRED provides different levels QoS for them. This paper concludes that RED and WRED two congestion avoidance mechanisms can provide certain QoS guarantee for network applications.
