Re: [LARTC] hfsc scheduler
I'm using HFSC. But I haven't had time to really understand how to
correctly define curves. So i'm using it the linear way.
I'm just using a rt service curve for my interactive class. (but the
root class is a linear one)
for sure a simple example for a real case could help.
hmm in my case on my 2028/256kbits adsl line: my classes are roughly
defined like this:
root
/ \
interactive bulk_parent
/\
normal boring_bulk_parent
/ \
syn+small_acksreal_boring_bulk
/ | \
host1 host2host3
(ul rates are near 240kbits, it's a bit less for "boring" classes)
My interactive class is defined like this:
... ls umax ${MTU}b dmax 25ms rate ${MAX}kbit \
rt umax ${MTU}b dmax 25ms rate ${MAX}kbit
25ms, it's a bit less than the latency i have when my link isn't used.
i guess my setup is not really coherent. bulk_parent shouldn't be a
linear service class. And if that's true, all its leaf classes
shouldn't be linear services ones.
another thing, (an example is better than a long long phrase:)
using the same class tree with htb:
host[1-3] upload at 25kB/s, if I start a ftp upload (normal bulk
class), it takes precedence, host[1-3] are slowed and the ftp upload
gets(sends at) more than 25kB/s
I'd like to use HFSC and always have that behavior.
I'm pretty sure a howto-use-hfsc-in-real-context+faq could help. :)
unfortunatly I'm afraid not a lot of people can write it :)
i've read the theory docs, english isn't not my monther tongue language
and for me there's a huge gap between hfsc theory and hfsc in a real
situation.
Anyway, many thanks to Patrick for his work and the documentation he
wrote.
at the moment, for my usage, i prefer to use HFSC rather than HTB.

[...] the only documentation i know about classify is provided by patch-o-matic. You may prefer to use "handle $mark fw" as a filter to match netfilter marks. Or depending on your needs, you may only want to use u32 without netfilter marks.
