Abstract
Random early detection (RED) was developed to improve the congestion avoidance behaviour of TCP/IP traffic, but can also benefit real-time interactive applications. A novel solution is developed for a RED controlled buffer, modelled as an M/M/1 queue. This gives explicit formulas relating load, performance, and RED configuration parameters. Results for VoIP demonstrate that RED regulates the mean delay and delay variation under congested conditions, and that the new analysis accurately bounds performance
