Consider using HFSC. HTB is not the best solution for such a number of classes with small rate. Users will not be able to get the whole ceil even if there will be avaliable bandwidth. Secondly make sure your're using kernel with double linked list patch applied to qdisc api. -- Tomasz Paszkowski pgp6suZVgTBMn.pgp Description: PGP signature
[LARTC] problems with hfsc
Hello, I've discoverd hfsc few days ago, and for me it's great ! I'am running it on linux 2.4.26 with vlan interfaces using iANS. During tests I've discovered few problems. My set of rules is quite big: [EMAIL PROTECTED]:/home/system/scr/etc/hfsc_rebuild# cat tc.batch | grep hfsc | wc -l 27900 and alwyas when I delete the root hfsc class, machine is loosing network conectivity for about 15 seconds. The second problems is that after reloading set of rules machine is losing network conectivity on some virtual interfaces. As I remember the same problem was present in the earliest version of linux kernels (< 2.4.26) in htb code. -- Tomasz Paszkowski pgpqgTwzL3d7c.pgp Description: PGP signature
