hfsc guide

Hi *,
I read http://linux-ip.net/articles/hfsc.en/ on hfsc qdisc, but I don't understand this qdisc very well. Is there other documents about that? I didn't find.

Thanks in advance,
Fabio

There is lot of HFSQ info around the net, just use google. Some fine examples:
http://www.cs.cmu.edu/~hzhang/papers/SIGCOM97.pdf - A Hierarchical Fair Service Curve Algorithm for LinkSharing, RealTime and Priority Services
https://calomel.org/pf_hfsc.html - Hierarchical Fair Service Curve (HFSC) of OpenBSD
http://www.openbsd.org/faq/pf/queueing.html - PF: Packet Queueing and Prioritization
The last two are not linux implementations, but may put some light into the qdisc itself.

Greets, Ivan

I've been preparing man pages, but they still need a bit of work. Either way -
