Re: [LARTC] How could I do this?

[Martin Devera <devik@cdi.cz>]

IMHO u32 with hashes could be used for this. Other interesting
way is that CBQ & HTB allows you to set packet's class from
priority. When priority is 0x10003 then the packet is queued
directly into 1:3 queue.
You can simly modify classifier (in fact I will do it for
HTB) to allow such selection thru fwmark.
You can then mark flows by iptables .... --set-mark 0x10003 to
assign packet into 1:3 class ..
