What is there for good HSFC documentation out there right now anyways?
There is the original papers by Hui Zhang et al., which is mostly
about the theory and not very suitable for users - but still worth
reading if you're not scared by use of some math.
There used to be some documentation called "HFSC for Router Plugins",
which is partially applicable for Linux .. and some ALTQ and *BSD
documentation which is partially applicable as well. Besides that
there seem to be a few german student research projects about this
subject, but all I know of are in german. Last thing I know of is
an article written by a friend of mine for the german Linux Magazin,
unfortunately also only in german, but reviewed by myself and mostly
correct (klaus.geekserver.net/hfsc/hfsc.html) - translations are
welcome :)
I forgot to mention, there is actually a quite easy way to get
started with HFSC if you already have a working HTB setup. Just
delete the "prio" statements, replace "htb" by "hfsc",
"rate" by "sc rate", "ceil" by "ul rate" and delete all the
remaining htb specific parameters and you have something working.
One thing to note is that HFSC will drop, rather than pass unshaped,
traffic that is unclassified.
So if you don't use a default class and don't filter arp to a class then
HFSC will appear broken whereas HTB will work.
