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

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

Hi fellows: Im wondering about compiling cls_u32 sch_htb and bridge into the kernel Are there any advantages or disadvantages doing this in terms of stability or crash problems?

hi i ve seen one of your replies here and i saw that you receomend 2 modifications in the kernel files in order to improve htb. first in pkt_sched.h, changing PSCHED_JIFFIES to PSCHED_CPU. and then, sch_htb.c, changing HYSTERESIS from 1 to 0. is it that simple? i mean i just change these here variables and i get better results? i ve done a search and found the first file in 3 locations. where exactly do i do these modifications? tnx

Hi everybody, I''ve got a little problem when adding HTB support to my SUSE 8.1 by patching its kernel 2.4.19. After i patch kernel getting some errors, the HTB kernel option shows up but when i make modules it finds something wrong with the sch_htb.o module. Could somebody give me a hand on this?

The HTB scheduler code is a mess, this patch set does some basic house cleaning.

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 all, I am compiling a 2.4.19 kernel. I downloaded the kernel source from familiar project, which is a project working on porting linux to ipaq handheld devices. The question I have is what patch should I apply: htb3 or htb2? Also, I looked into htb3 patch. There are the source for sch_htb.c and some definitions that should be added to pkt_sch.h. I already have a sch_htb.c in my kernel source but nothing in the pkt_sch.h. My question is how to tell which one is newer: the sch_htb.c in the patch or the one I already have? Any suggestions would be appreciated. Thanks, Ya-Yunn

Another question:I am studying sch_htb.c,but it's so tough for to understand,especially htb_dequeue().Would anyone please supply some adivse?

I was using this setup and it worked fine untill i executed up2date in Redhat and updated a lot of the packages in linux. When i run the following script i get an error, which i pasted bellow.

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. _______________________________________________ LARTC mailing list / L...

All: I have been told that HTB_HYSTERESIS might have some effect on rate calculations. This file is usually in /usr/src/linux/net/sched/sch_htb.c. If I change this file I have to re-compile. I am not quite sure how to do this. Can someone list the steps necessary to re-compile or point me to a doc that explains how to do so. Thanks.

...k) Another user with higher priority starts downloading, and for the first few seconds only get a fraction of what he really needs, but then suddenly, the speed increases, and the low-prio user looses his speed. Is there a way to make this "kick in" start faster? I checked the net/sched/sch_htb.c and found: #define HTB_EWMAC 2 /* rate average over HTB_EWMAC*HTB_HSIZE sec */ Could decreasing this to like 1 second fix the issue?
