This paper exposes an inherent weakness in current active queue manage ment techniques such asRedin that they rely on queue lengths to indicate the severity of congestion. In light of this observation, a fundamentally different active queue management algorithm calledBlueis proposed.Blueuses packet loss and link utilization to manage congestion. Using simulation and controlled experiments,Blueis shown to significantly outperformRedin providing lower packet loss rates and smaller queuing delays to networked applications such as interactive audio and video.
