As more and more interactive applications (e.g. voice over +IP, real time video streaming and financial transactions) run in the Internet, +high latency and jitter degrade application performance. There is a pressing +need to design intelligent queue management schemes that can control latency and +jitter; and hence provide desirable quality of service to users. + +We present here a lightweight design, PIE(Proportional Integral controller +Enhanced) that can effectively control the average queueing latency to a target +value. Simulation results, theoretical analysis and Linux testbed results have +shown that PIE can ensure low latency and achieve high link utilization under +various congestion situations. The design does not require per-packet +timestamp, so it incurs very small overhead and is simple enough to implement +in both hardware and software.
