There are many factors that are important in the design of queue management schemes for routers in the Internet: for example, queuing delay, link utilization, packet loss, energy consumption and the impact of router buffer size. By considering a fluid model for the congestion avoidance phase of Additive Increase Multiplicative Decrease (AIMD) TCP, in a small buffer regime, the authors argue that stability should also be a desirable feature for network performance. The queue management schemes the authors study are Drop Tail and Random Early Detection (RED).
