Abstract:

As application requirements become harder to satisfy, people are
seeking for new Active Queue Management (AQM) policies that
can make end-to-end control much easier to achieve. As a
pioneer, RED had been a hot subject in a large body of
performance studies. People found out in many cases, RED
parameters are very hard to calibrate, and RED suffers the
problem of slow response to load change, which result in
oscillatory behaviors.

In this talk, we will review some recent proposed solutions
to the problem mentioned above. These works include BLUE,
which try to stablize packet dropping rate at the queue,
and PI-RED, which try to stablize queue length. We will also
talk about some other end-to-end issues.
