Abstract:
Bufferbloat is a phenomenon where excess buffers in the network cause
high latency and jitter. 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.
