Hey, fellow LART controlllers, I''d like to ask if someome has a real esfq experience with HTB class hierarchy and esfq qdiscs. Lets say that I want to unite the connections to 10 client PCs with u32 or fw filters (doesn''t matter which one in fact) into one HTB class with esfq qdisc at the end. Did anyone tried it, and more important, did it worked the way it is supposed to? As

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

...this case if the above class 1:20 with PRIO 0 requests packets, than the class 1:30 must receive only 1kbit (the specified RATE), nothing more. In practice class 1:30 shares the bandwidth with class 1:20 and gets not 1kbit, but much more >20kbit. I have TSL 2.1, kernel 2.4.27-3tr. I changed the PSCHED_CPU and disabled the HTB hysteresis, set SFQ queue length to 16, but the results are the same. Is there something wrong with my understanding? Can anyone explain why PRIO not works? Regards, Zviad _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://m...

Hi there, I was wondering if it''s possible to use PSCHED_CPU (cpu cycle counter as clock source for QoS). Normally kernel menuconfig forbids it due to lack of synchronization of counters on different cpu, but: http://uwsg.iu.edu/hypermail/linux/kernel/9902.0/0053.html and quoting interesting part... ------------- checking TSC synchronization across CPUs:...

Hi again, sorry to be such a bother. I got my setup to work with kernel 2.6.8.1, however the two machines where I need to implement the shaping are running a 2.4.27 kernel. I have applied the infamous June patch (htbfair.diff) already, and recompiled the modules. And I am using the tc that comes with htb3.6-020525.tgz. While I can see the packets going into the right class, it does not

I´m shaping with htb with a kernel 2.4.25 compiled with PSCHED_CPU. What i´m noticing (in mrtg) is that traffic coming in to eth0 (internet side) is much bigger than eth1(Lan side). I think this is due to packets being dropped right? In this case, is there any way to avoid this? because right now traffic coming from the router is being wasted right? This is the o...

During my tests I''m starting to feel stupid :). Traffic shaping works quite on its own. System: RedHat 7.3, RedHat kernel 2.4.18-18.7.xsmp, HTB version 3.6, interfaces eth0 and eth1 are acting as bridge br0. If TCP shaping almost works, it just exceeds limits UDP is not shaped. Traffic flows PC=>eth0=>eth1=>PC. Statistics shown is for just UDP traffic (1mbit of small udp

Hello everyone: As it is known, when you limit uplink bandwidth it usually gets downlink bandwidth to a lower value. I just want to know what is the optimal configuration for eth1 and imq0 according to some variables of tc(HTB), txqueuelen, mtu, etc. to make these packet flows less independent on an ethernet based network. Thank you in advance. -Diego

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I''m absolutely new to tc and found The Ultimate Traffic Conditioner to be exactly what I wanted as a starting point. Now the script doesn''t behave as I expected though, which applies to both the CBQ and HTB versions, the latter of which being my preference. The only changes made to the script are these assignments:

Hi, New to traffic shaping I would like to make some tests. It''s for a production server (fw), using 2.4.27 kernel. Something is not clear to me about HTB... is the last stable version included in the 2.4.27 kernel and iproute2 (iproute2-2.6.8-040823.tar.bz2) ? Are there special patches to apply ?

Hello good day to all ... this is my setup 1 Linux Wireless Access Point, connected are 4 wireless gateway in which i needed to apply shaping ... ok here is the weird part... clients on each gateway download files from the Acess Point ... a 500 mb file through ftp on gateway 1 which is up to 64 kbps ... the result is from 60-64 kbps speed which is fine ... on gateway 2 which is 128 kbps ... the

Hi, I''m trying to setup QoS in my TSL box. Following to mailing list reccomendations I changed PSCHED_CPU but can''t get accurate shaping with HTB. I have disabled HYSTERESIS also (by setting it to 0). I have Intel Celeron 1.8Mhz (TSC supported I think). ******** My script ****** tc qdisc add dev eth0 root handle 1: htb default 22 r2q 10 # Class corresponding interface throughput tc class add...

Hello one more time, As others seem to already asked without reply, I''m getting lower speed rates than specified via ingress. How do I know. Because I have this in my script: tc qdisc add dev $DEV handle ffff: ingress # Filter intranet traffic, so fit it to intranet speed tc filter add dev $DEV parent ffff: protocol ip prio 10 u32 \ match ip src $Q_2_HOSTS \ match ip dst
