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 there! Yesterday I started my experiments with HTB. I configured it this way: 1: root HTB qdisc | 1:1 HTB class rate 1000kbit | /-------+------\ 1:40 1:50 1:60 user1 user2 user3 rate 333 & ceil 1000 for everyone. User2 is disconnected and user1 and user3 are downloading. For all the time (t1-t5) there are ONLY these two users downloading! HTB should give

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 new to HTB and CBQ, and i want to try it. But i failed the first step: load modules. I patch the kernel 2.4.17 succesfully, add QoS support, and all QoS scheds in modules instead off kernel. make clean dep bzImage modules modules_install copy the new kernel reboot fine But when i : server:~# insmod sch_htb Using /lib/modules/2.4.17/kernel/net/sched/sch_htb.o

The HTB scheduler code is a mess, this patch set does some basic house cleaning. The first four should cause no code change, but the last two need more testing. -- Stephen Hemminger <shemminger@osdl.org> "And in the Packet there writ down that doome" - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to

Hi, Trying htb (latest patches from the page) with 2.4.17 I get: RTNETLINK answers: File exists iproute is 20010824 with the patch from the page. The kernel module loads, but is not used: sch_htb 12672 0 (unused) Any ideas? -j

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

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, 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 have strange problems with HTB and several hundred classes flat structure i.e. root |--50kbps |--30kbps |--50kbps |--80kbps |--100kbps .... several hundred classes like this Ceil is the same as rate. The machine get no more than 2-3% average cpu(2.4Ghz pentium). What happens is that from time to time the traffic got "stalled". I tried numerous things to solve

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

//Just to not forget eth0 is WAN and eth1 is LAN . The box is NATing my lan. I configured tcng to shape both download and upload and i got connection loss again.

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, 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/
