similar to: htb and hfsc

G''Day I would like to be able to use my VOIP telephone over a saturated ADSL link whilst enjoying optimum audio quality and utilising all of the bandwidth I pay for. It is about this situation that I write. HFSC appears to be the queueing discipline of choice for VOIP. In order for this to work, though, do I have to account for the ATM overhead in the small VOIP packets by defining my

hi all, long time since i posted on the list. just wondering if anybody has played around with hfsc and if so could he/she share their info on it thanks adrian -- To mess up a Linux box, you need to work at it; to mess up your Windows box, you just need to work on it. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Hi, I''m trying to make run a simple shaping *through HTB*. I have compiled a new kernel 2.4.21. First command from http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm said: # tc qdisc add dev eth0 root handle 1: htb default 12 RTNETLINK answers: Invalid argument I tryed both standard tc from Debian stable and http://luxik.cdi.cz/~devik/qos/htb/v2/tc.gz this one... I tryed

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

Witold Szczerba spent his time evaluating fairness of borrowing. His troubles inspired me enough to analyze the problem: When a class changes from yellow to green it disconnects itself from parent''s feedlist. Unfortunately it resets feed pointer to the first child. I created a patch where the class uses classid to remember its position in the feedlist. The patch for 2.4.24 and hopefully

Hi, I am new to tc, please forgive me for simple question. I have linux 2.4 in my routers, I would like to use HTB. I have downloaded binary code from http://luxik.cdi.cz/~devik/qos/htb/#source, (tc.gz), but I could not open the file. Is there any other place I can get binary code for HTB. Also if you can give some direction how to patch it, it will be really helpful. Thanks in advance Omer

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.

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.

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, I''d like to try out HTB for traffic shaping. I have a test machine with Redhat 7.2 (kernel 2.4.10), I''ve downloaded kernel 2.4.17, applied the patch from http://luxik.cdi.cz/~devik/qos/htb/, recompiled the kernel (checked the option to use HTB in make menuconfig), and rebooted with the new kernel. When I try to add some rules with HTB (f.i. tc qdisc add dev eth0 root

I have a lot question about tc-command because now i''m doing research to compare performance between HTB and  HFSC so i''m doubt a lot thing and your reply are so very helpful to me ... My question is In HTB tc command question 1. I''m use opensource (Mastershaper) for help to config traffic control but when i''m try to config HTB, I''m doubt about

now i''m read a lot of knowledge paper about traffic control in linux because now i''m try to develop and research about traffic shaper so can everybody tell me about my topic ... Is it can do for real???? my topic is " now, many organization use traffic shaper for control traffic and bandwidth because don''t want something example some mac address, ip address,

hi there, this is my 1st message in the list. I would like to use this wondershaper.htb to limit the bandwith usage at home. My kernel config is: # QoS and/or fair queueing # CONFIG_NET_SCHED=y CONFIG_NET_SCH_CBQ=y CONFIG_NET_SCH_HTB=y CONFIG_NET_SCH_CSZ=y CONFIG_NET_SCH_HFSC=y CONFIG_NET_SCH_PRIO=y CONFIG_NET_SCH_RED=y CONFIG_NET_SCH_SFQ=y CONFIG_NET_SCH_TEQL=y CONFIG_NET_SCH_TBF=y

Hopefully someone has a suggestion on how I might do this...as I can''t figure it out :( I need to be able to set up a group of seperate users who have a "bandwidth pool" they share, but also be able to limit their individual bandwidth as well. Example: I have 5 customers and would like to be able to provide them with a maximum of 256Kbit each, with a CIR of 33%. To do this,

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

Hello all, I´ve read http://lartc.org/howto/ and now i am just confused, i think my skills with linux are not very good, so asking for help. I have a linux box with two ethernets cards eth0(gateway 1mb) with is the host for some sites and emails and eth1(nat interface) with provide internet acess to other 5 pcs. I would like to limit the bandwith 512 k for the eth0 and 512 k for eth1 however

Hi, Hope someone can help me. I am a student who hass been given a project to develop a dynamic bandwidth service. I currently have a linux router which at the moment gives users static bandwidth and assigns each of them to a bucket. I have not gotten information yet as to whether each bucket is serviced in a round robin fashion or whether certain buckets get preferential treatment (i.e. bucket

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
