...k of it myself. Compression: Another thing that might be useful to the list is the use of compression (Deflate etc.) to get better bandwidth across links. This requires a Linux router at both ends of the link. I got the idea from a product called Peribit see www.peribit.com ( and mainly from Martin Devera who pointed out to me that Linux does compression already with ppp. ) I have now started to work on getting compression built into my traffic shaping/router products that are Linux based. Putting that in place of Cisco should be a much better/cheaper solution do you not think? One could even shape...

hi all, i want to try htb3 with imq downloaded & patched imq & htb3 with kernel-2.4.18 on rh7.2 but got STUCK on step 1 :( this are what i did can anyone guide me what went wrong on the first step itself !! [root@cab1 root]# modprobe imq numdevs=1 modprobe: Can''t locate module imq [root@cab1 root]# [root@cab1 root]# tc qdisc add dev imq0 handle 1: root htb default 1 Cannot find

Hello, I have an interesting question. I can''t find a solution anywhere to this problem. I have an adsl connection which is able to send a full data packet in about 150ms. I want to cut this time down to decrease latency while serving files, so I thought I''d try and reduce the packet size for the offending upload streams (my webserver). The trick is that I also want all other

Hi, for interested in participation on finishing new HTB developement I created simple docs regarding it. It is some insight into CBQ and HTB workings and problems. See luxik.cdi.cz/~devik/qos/htb/v3/

...ed his terminology to INPUT,OUTPUT, and FORWARD. Was he not using the terms egress and ingress correctly? I see that the current ''big'' problem is touching locally generated traffic. What I need to know is which version of IMQ is most stable for kernel 2.6? Or even kernel2.4? Is it Devera''s? McHardy''s? Correa''s? or Roy''s? Or should I just leave it alone? My apologies if I got names wrong. This is probably a long email just to ask that question, but I can''t seem to find an answer from the list archives. I downloaded the whole 46 mb archiv...

I would like to differentiate incoming traffic streams to guarantee minimum bandwidth to some services. However, as per the Adv-Routing-HOWTO it appears that only outgoing traffic can be shaped. Is this correct or is there a way of shaping incoming traffic? The problem could possibly be overcome if there is a way of routing traffic through a virtual host. Any tips on how to go about that? --

Can I use the same SFQ queue dicipline for all the classe in a CBQ or HBT system?

Hello, I think the BUG_TRAP() in the htb_dequeue_tree() is wrong. First it checks if the class pointer "cl" is NULL, which is obviously right. But I do not understand why we also check whenever the queue length of the leaf queue is zero "cl->un.leaf.q->q.qlen". I would have put that in the expression of the "if" statements that comes afterwards. A queue

I run a small Linux webserver and NAT router from my cable modem at home. Whenever someone starts an http download, all other traffic from my LAN is starved. Bandwidth is not really an issue, but latency is particularly horrible -- pings that usually come back in 20ms can take up to 600ms while the web server is active! I set up QoS (netfilter+iproute2) on the NAT machine in an attempt to give

Hello, I''ve been using cbq''s "weight" parameter to influence distribution of excess bandwidth among sibling classes. Does htb offer something similar? So far I think that - you either use priorities - then excess bandwidth is offered to higher priority classes first, the rest (if any) is distributed among lower priority classes - or you don''t use
