similar to: "weight" parameter in htb?

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

Hi, I''m a bit confused with the priority of different classes with HTB. How it will be? Will the class with lowest no: have maximum priority? Any help is most appreciated, Thanks in advance, Sanjeev -- ______________________________________________ Check out the latest SMS services @ http://www.linuxmail.org This allows you to send and receive SMS through your mailbox.

Hi Stef and Alexey I have read some documents about CBQ algorithm from http://www.icir.org/floyd/cbq.html but still have some question about CBQ in Linux . 1. First estimator can estimate how much bandwidth already USED per class. one estimating algorithm is EWMA (exponential weighted moving average), how about Linux implemenatation about estimator? also do you have link for this algorithm? I

Hello, Does anyone know when one should use cbq versus (simpler more accurate) htb? Specifically does cbq have added functionality that may be of interest to certain applications? from htb home> Both CBQ and HTB help you to control the use of the outbound bandwidth on a given link. Both allow you to use one physical link to simulate several slower links and to send different kinds of

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

Hello, Normally, in addition to such qdisc scheduler mechanisms as FIFO, PQ, WRR, WFQ, are there any more? Then, there is a confusion on scheduler in Linux enviroment: Assume there is a qdisc, such as RED as a leaf qdisc in a router, we know, if there is packet which want to enqueue the packet, the Function red_enqueue is called, but when the packet leave the queue(when the Function red_dequeue

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/

The manual says (about prio): > Because it doesn''t actually shape, the same warning as for SFQ holds: > either use it only if your physical link is really full or wrap it > inside a classful qdisc that does shape. The latter holds for almost all > cable modems and DSL devices. I want to wrap prio inside of tbf. Here''s why: I have a server on a DSL line, which has

If I create a cbq qdisc as a leaf of a cbq class, the bandwith rate is the same of the root cbq qdisc or the rate of the cbq class? Does exist the parameter rate on the "tc qdisc add" for cbq command? tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 10mbit avpkt 1000 cell 8 tc class add dev eth0 parent 1:0 classid 1:3 cbq bandwidth 10mbit rate 50kbit allot 1514 cell 8

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

Hello, I have been searching for HTB theory documentation and found two interesting sources - Devik''s page and docum.org FAQ. In some places they are contradictory which make me think that Devik''s theoretic document (marked "actual") is just too old and does not reflect the latest changes. After reading http://www.docum.org/docum.org/faq/cache/30.html and others, I

Hi, I''m new to HTB and CBQ, and i want to try it. But i failed the first step: load modules.

Hi - I''ve been going through the LARTC how-to and have successfully used the sample scripts (and wondershaper) with my xDSL links. I''m now faced with the challenge of providing 8 users at work an effective remote access connection over a PSTN ppp connection. The critical traffic in this case relates to our stock enquiry application which is running over terminal services.

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? --

I notice one other small problem with my modified version of SFQ. The fact that packets can be dropped at dequeue time is incompatible with the way HTB (and probably CBQ and others modeled on it) keep statistics. When I fill a low rate queue causing packets to expire and be dropped at dequeue I get interesting statistics like this: This is my variant of SFQ qdisc plfq 8016: dev eth1 ... Sent

Hello all! As far as I know that the traffic that will pass thru the router is balanced so that all connections have the same privilegies. Is it possible to configure the linux based router so that all computers will have the same privilegies? I mean that if in default case full traffic is splitted by connections, so I need to split it by users to prevent one user occupy all traffic by starting

Hello, I''m a total tc newbie, and I''m trying to tweak the wondershaper script (http://lartc.org/wondershaper/) to get a slightly different result. Excuse me if I will not use the correct technical terms, it''s a whole new world to me :) wondershaper.htb creates 3 HTB classes; 1:10 is high prio, 1:20 is bulk (default), and 1:30 is low priority. The classes are

I''ve just started to recently look at CBQ and HTB, but I''ve been wondering whether or not something like the following is possible: I''ve got two external links: +--+ | |-----ISP1 |FW| | |-----ISP2 +--+ One link has a bandwidth cap, and the other doesn''t. What I want to do is, punt all outbound traffic out via ISP1
