A Comparative Study of Queue, Delay, and Loss Characteristics of AQM Schemes in QoS-enabled Networks

摘要: One of the major component in a QoS-enabled network is active queue management (AQM). Over last decade numerous AQM schemes have been proposed literature. However, much recent work has focused on improving performance through alternate approaches. This study focuses an unbiased comparative evaluation various proposals. The methodology adopted following: we first define relationship between terminologies used this paper, briefly introduce queue, delay, and loss characteristics-- subset characteristics that can be to describe behavior entities, give their mathematical description. Next, present method would successful case based NS simulation technique simulation-based comparisons chosen, which will help understand how they differ from terms per-node queueing information per-flow end-to-end behavior. Simulation results showed PI schemes, feedback-based mechanism, assist delay sensitive applications adapt dynamically underlying stabilize QoS within acceptable requirement. To attribute important for proper design disciplines, provisioning queues link capacity, choosing parameters simulation.
