Hi All, I am fairly new to Linux and TC. I am currently implementing Bandwidth Management/Traffic Control for a gateway product which is based on Linux 2.4.18 kernel. I am required to implement some kind of a user based traffic control where each user(source IP) is allocated a fixed amount of bandwidth. I also need to do traffic shaping both for the eggress and ingress traffic. Going through LARTC documentation , I found that IMQ with HTB will suit my requirement. Is anybody using IMQ with HTB? Can HTB and IMQ work with 2.4.18 kernel? If so, where can i download all the patches? It is difficult for us to migrate to 2.4.20 kernel as most of the software has already been developed using 2.4.18 kernel. I really appreciate any help in this regard. Thanks, Hemanth --------------------------------- Do you Yahoo!? Yahoo! Tax Center - forms, calculators, tips, and more

If you have a gateway, you can shape on both interface so you can control up- and download traffic. Just wondering, what kind of software do you developped so you can not use kernel 2.4.20 ??

Hi All, Thanks for the help. Stef, our product is already out in the market with 2.4.18 kernel. So if we change the kernel, we will have to go through a full QA cycle which is something we don''t want to do :). BTW, I would like to have global limits on the Bandwidth per user irrespective of which interface the traffic might go.Can i do this without using IMQ? Also i want to do my own classification by setting the skb->priority field with the appropriate class ID. Is it possible to use this kind of classification with IMQ and HTB? i really appreciate your help.

Hi, There is no options at all to ''shape'' upload+download=fixed bandwidth without using IMQ virtual device ? So if somebody is planning to give customer fixed bandwidth regarless if a customer is ''uploading'' or ''downloading'',he (or she:) MUST use IMQ virtual device ? Anybody did some tests of configuring same traffic shaping with and without using IMQ device ? How IMQ device (kernel) will behave on heavy load traffic (like VoIP,gaming,other ''real-time'' traffic) comparing on mashine without using IMQ virtual device ? Does anybody did some test on using u32 filter and fw filter ? How does each one behave on same mashine,same kernel,same traffic shaping configuration ? f2zubac On Mon, 24 Feb 2003, Stef Coene wrote:> On Monday 24 February 2003 21:19, hanumantha kavuluru wrote: > > Hi All, > > Thanks for the help.

This question comes up pretty often. Conceptually, we can do it in two ways. 1. All outgoing traffic is shaped on the interface which is internet facing say eth0. Then the incoming traffic will go the LAN thro'' eth1. In this case shaping outgoing traffic on eth1 is nearly equivalent to shaping incoming traffic on eth0 ( assuming all traffic is for the LAN and not for the host). Another option to limit incoming traffic on eth0 is to use the ingress qdisc and police rates to a cap and shape the bandwidth utilised on eth1 to the LAN. In the case above, bandwidth is apportioned as incoming and outgoing separately. In the case of many ISPs, they would like to allocate bandwidth for incoming + outgoing instead of dividing what is allotted further between incoming and outgoing. In such a case, IMQ device is used. Shaping IMQ will shape the aggregated traffic of incoming+outgoing.

Hi Mohan thanks for the brief explanation... about the IMQ so when IMQ should be used when the both in/out traffic same ? like fixed ( 64kbps, irrespective of in and out) or like IN is less and OUT is more ? or IN more and OUT less ?

Hare,
: i was going through this thread you mentioned if iam using this Linux
: box as a gateway, i dont required IMQ to control ingress and egress how
: can do with out IMQ, can you point me
:
: i have 2 interface eth0 and eth1 like to control bandwidth for my users
: both up and down
Since the router can only shape traffic it sends, you can shape your
outbound (upload) traffic on your Internet connected interface, and you
can shape your inbound (download) traffic on the internal interface as you
transmit to your internal network. Another way to shape the download
bandwidth is to use policing or ingress filters with IMQ.
http://linux-ip.net/htb-script
As Mohan explained, traffic control can delay packets already received
from the Internet before sending them to the internal network application,
thus simulating a user-specified download bandwidth. Similarly, upload
bandwidth can be controlled/shaped by delaying packets bound for the
Internet before sending them up to the gateway.
By the way, Stef is on vacation this week. I believe he said he''d be
skiing.
Good luck,
-Martin
P.S. I''m thinking of changing my name to
"A-router-can-only-shape-the-
traffic-it-sends." I forgot this *again* when I was writing this
script. Maybe then I''d remember!
