Performance evaluation of AQM schemes: a comparative study
Qijin Ji · DOAJ (DOAJ: Directory of Open Access Journals) · 2005
A taxonomy of AQM schemes was presented, and typical AQM algorithms were compared in terms of a number of performance metrics under different traffic and network topology conditions based on the NS2 simulation platform. The main results of this paper include: ARED performs better than other algorithms; PI controller and REM responses slowly to dynamic traffic; AVQ without ECN support and REM can maintain lower queue length but at the cost of lower link utilization and higher packet loss rate; The performance of AVQ is significantly improved combined with ECN; Most AQM algorithm perform better in multiple bottleneck link topology.
