similar to: SFQ for all classes

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

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

Hello, I am experiencing system hangs when running NFSv4 over a tinc VPN. I don't know if the problem is with NFS or tinc and would appreciate any suggestions on how to narrow down the culprit. Unfortunately I cannot simply run NFS directly over TCP -- the participating systems are connected only over an open network. The configuration is as follows: I have a master server

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

Can I attach a SFQ qdisc after a TBF qdisc?

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

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/

Hi anyone I try to use htb and got some strange situation My hbt config is root htb with default to 999 class Then I make 2 classes 999 and 998 And make many many (near 60) leafs attached to 998 root ! ! 999 998 ---...---> many leafs root attached to ethernet dotQ subinterface 999 make rate where high (50Mbit) but according to tc -s class

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

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 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 Devik/Patrik, In setting up IMQ/HTB with a GRE Tunnel I''m constantly getting kernel errors: [root@linux /root]# dmesg ... ... ... NET: XXX messages suppressed. Dead loop on virtual device gre1, fix it urgently! ... ... ... This I get only if I''m going to start cross device b/w control. If I remove iptables rule iptables -t mangle -D POSTROUTING -j IMQ then no such warning

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? --
