This is an implementation of the Quick Fair Queue scheduler developed
by Fabio Checconi. The same algorithm is already implemented in ipfw
in FreeBSD. Fabio had an earlier version developed on Linux, I just
cleaned it up and tested it. All bugs are mine.

  thanks for posting, I'm pretty sure that bugs are more likely to be
ours than yours :)

During the development of the algorithm we used a simple traffic
simulator to verify (informally) the timestamping and the guarantees
provided.  I've tested this version of the code with the simulator and
so far it worked fine, so I think that timestamping and guarantees should
be OK.

Please let us know if we can be of any help,
fabio

Hmm, I tried to setup QFQ (using iproute2patch
http://patchwork.ozlabs.org/patch/77902/ ) but failed

Do you have a link to a script/sample ?

Thanks

I put the iproute2 code into the repository in the experimental branch.
