Hi,
just simple note. Maybe it is already in progress :)
There are attempts to replace hashing routine in SFQ to
consider IPs or ports.
What about to use HRR - roundrobin around bunch of IP
adresses and then smaller WRR for ports per IP ?
It would solve both problems - fairnes between computers
(IP) and between flows on than single computer ...
HRR wouldn't that make things complicated?
I think it's better to have two simple separate solutions and a way to
combine them.
What you suggest means to put SFQ into SFQ - just different
classification. Some may wish even to have more levels -
SFQ into SFQ recursive.
Isn't it possible to arrange this with cbq and sfq leafs?
You probably now the IPs but do not know their connections.
There is a suggestion how to combine SFQ and RED with IMQ,
what about doing same but with SFQ and SFQ -
attach ESFQ with dst hash on IMQ and sfq on the network device?
Adding source/destionation port hash in esfq is very easy task.
A better solution would be to make classful SFQ.
Then you put sfq with one classification and attach to it
sfq but with different classification. Or you can put (G)RED on it.
Would get same as with IMQ but you'll get the N levels.
HRR with WRR would be great when you have to deal with a lot of
IPs, but what is the right way to do it?
