Hello

I've recently written and defended this university project report on
bufferbloat as part of my masters programme:

http://rudar.ruc.dk/handle/1800/9322 (or
http://akira.ruc.dk/~tohojo/bufferbloat/bufferbloat-final.pdf if the
first link doesn't work).

The paper compares four different Linux qdiscs in a simple lab setup,
and demonstrates bufferbloat, and the mitigation provided by fq_codel,
quite well. The first couple of sections on how TCP and the Linux
network stack work are probably known material to most people here, so
feel free to skip to the experimental setup and results in sections 5
and 6.

I hope you will find this interesting; feel free to comment and/or ask
questions. :)

-Toke
