Hmm, so why don't you use CBQ/PRIO and maybe GRED then, i.e. something that gives AF priority over BE ? > To solve these demerits, I made ingress marker in linux kernel 2.4.x. > that is, I take DSCP marking part 's position in input device part . You don't have to mark in order to classify based on the DS field. Just use skb->tc_index to convey that information. You can set skb->tc_index at ingress or at egress (with dsmark). - Werner -- _________________________________________________________________________ / Werner Almesberger, Lausanne, CH wa@xxxxxxxxxxxxxxx / /_http://icawww.epfl.ch/almesberger/_____________________________________/
