Hello! I need to switch from htb2 to htb3, because of speed issues (for me, htb2 is unable to handle more then 100mbit duplex with ~550 classes), kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation. So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking and htb3 for queueing), and traffic rate drop from 100 to 20mbit. What can be wrong? The

...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.

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/

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 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 trying to make run a simple shaping *through HTB*. I have compiled a new kernel 2.4.21.

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

I posted earlier when I noticed that htb was releasing packets in pairs, even though my burst/quantums were 1 pkt. To fix I set HTB_HYSTERESIS 0 in net/sched/sch_htb.c . This gives a noticable gain in upstream worst case latency, for me with 256kbit/s up I used to see +90 sometimes, now it''s +45. For the many who have 128 up it should limit them to +90 rather than +180. Andy.

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

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 --------------------------------- Do You Yahoo!? Yahoo! Tax Center - online fi...

Devik, Can you send Htb to Marcello Please? Its only a module, but its about time it went mainstream. Maybe its too late for 2.4.19, but 2.4.20 will come. Same comment for IMQ also. Regards John

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? --

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
