I can use DSMARK to mark on the Egress side. Is there a way to mark/change the DSCP value of an incoming packet on the ingress side? Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

Hi! I am studying HTB. I used the topology showed below: 10.1.0.1 ------ 10.1.14.25 (eth1) / 192.168.10.10 (eth0) ----- 192.168.10.11 (host 1) (router) (host 2) All machines use Debian Etch. Has a Iptables masquerading rule to eth1 in the router machine . The NICs are 100 Mb/s. The host 1 has Apache 2 and a file with 670 MB (CD ISO image) to download. When I used

Hello, I am trying to mess with a prio type qdisc, and must be missing something. Here''s my sample code: tc qdisc add dev eth0 root handle 1: prio tc filter add dev eth0 parent 1:0 prio 1 protocol ip u32 \ match ip dst 208.0.0.0/8 flowid 1:1 tc filter add dev eth0 parent 1:0 prio 3 protocol ip u32 \ match ip dst 0.0.0.0/0 flowid 1:3 I would assume that any traffic going to

I''m trying to configure 4 queues with strict priorities based on DSCP. I tried to following commands, but it seems that the filters I defined have no effect tc qdisc add dev eth0 root handle 1: prio bands 4 tc qdisc add dev eth0 parent 1:0 handle 10: pfifo limit 100 tc qdisc add dev eth0 parent 1:1 handle 20: pfifo limit 100 tc qdisc add dev eth0 parent 1:2 handle 30: pfifo limit 100 tc

...ave some effect on rate calculations. This file is usually in /usr/src/linux/net/sched/sch_htb.c. If I change this file I have to re-compile. I am not quite sure how to do this. Can someone list the steps necessary to re-compile or point me to a doc that explains how to do so. Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

Hi there! I''ve using HTB for a while and now I an faced with a ''problem''. How hierarchical is HTB? Let''s say I have this 3 layer HTB setup: root class 1: (rate=100, ceil=100) 1: children classes 1:10 (30,100) and 1:20 (70,100) 1:10 children classes 1:100 (10,100) and 1:101 (20,100) 1:20 children classes 1:200 (30,100) and 1:201 (70,100) I managed to have

...or that packets are for sure going into a prio queue with TC? I can see all the HTB stats but the prio classes just list as being there...would like more information Basically I have the following setup DSMARK | HTB - (tcindex filter on TOS) | Prio (u32 filter on TOS) Thanks Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

I want to limit pps (packets per second) not just bandwidth on the ingress side. I can do this using IP tables but I''m curious if there is a way to do this with TC. Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

Hey everyone, For some reason my htb configuration isn''t allowing any class to burst up to its ceiling ever, even when the link is only being utilised by one class that class only ever gets its assigned rate and exactly that assigned rate... The hierarchy I have is 1: at the root with no default, then 1:2 and 1:3 under that, both with assigned rates, then 2: and 3: under those

...SVP PATH, RESV, and CONF message is sent. How does the Deameon know to setup a connection though? There is something internal at the client source happening. I just haven''t figured it out yet. Is it listening to a certain port? Any help would be appreciated. Thanks in advance. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

Does anyone on hear have any thoughts on the changes that would be nessary for KOM RSVP to use HTB rather than just CBQ and HFSC? Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

All: I''m trying to get RSVP running on a Linux machine. The machine is currently Fedora. I have read rfc 2205. Does anyone know where I can get the RSVP source code to install on the machine. Or does anyone know of some documentation that might help in doing this? Thanks, Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7
