similar to: [PATCH 2/2] Runtime configuration of HTB''s HYSTERESIS option (userspace)

The HTB qdisc has a compile time option, HTB_HYSTERESIS, that trades accuracy of traffic classification for CPU time. These patches change hysteresis to be a runtime option under the control of "tc". The effects of HYSTERESIS on HTB''s accuracy are significant (see chapter 7, section 7.3.1, pp 69-70 in Jesper Brouer''s thesis: http://www.adsl-optimizer.dk/thesis/ ),

Hello ! Have anyone got an iproute2 source with HTB which I can compile with the includes of kernel 2.4.21 or higher. I had one but I get the following error msgs: q_htb.c:338: redefinition of `explain'' q_htb.c:32: `explain'' previously defined here q_htb.c:357: redefinition of `explain1'' q_htb.c:51: `explain1'' previously defined here q_htb.c:366: redefinition

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 all, I patch my kernel (2.6.17) and my tc (iproute2-2.6.18-061002) utilitie for an accurate packet scheduling on an ATM link. I configure my HTB hierarchy on the upload of the link and try with differents flows. It works correctly but in some of case I lose about 50% of my bandwith. I use the overhead (42) configuration for my link (PPPoE, VC/LLC) indicate in the documentation. My question

I have been trying to optimise my ADSL connections for VOIP. Funny things were happening - for example increasing the ping packet size by 50% had no effect, but then adding one byte had a major effect. It took me a while to figure out that I was seeing the effects of the fixed ATM cell size. This is probably obvious to some of you. For the rest: ADSL uses ATM as its transport. An ATM

Can anyone suggest a package or code for modeling a hysteresis process in R? I'm currently modeling a certain dataset with a GAM using mgcv, something like gam(y~ s(x, by=z) + z, family = Gamma(link=log),data=data) and getting fits with about 9 estimated degrees of freedom in the smooth for each value of z. FWIW, z is a treatment applied to a system which should have made an improvement,

Hi, I''m getting this warning/error in /var/log/messages: May 26 18:21:05 mail kernel: HTB: quantum of class 10010 is small. Consider r2q change. Its a big deal? What should I do? Many thanks Oliver -- Oliver Schulze L. <oliver@samera.com.py>

Hi all, I am using htb for traffic classification. Is there a limit to the value prio can take cos when I give the following command . tc class add dev eth2 classid 1:22 parent 1:2 htb rate 500Kbit ceil 1000Kbit prio 8 and then check the output, I find that the prio of 1:22 is 7, same case for other values above 7. Thanks, Vinod C

Hi, I have a Debian based NAT router. How can I manage upstream egress bandwidth based on the LAN ipadress in the network below? My goal is that host1 get a minumum of 10Mbit up/down and host2 gets a minimum of 90Mbit up/down, both max 100Mbit up/down? targethost 172.16.255.254 | | 172.16.0.1 natrouter

Wherever we had code which did: if (something_bad) { perror (...); exit (EXIT_FAILURE); } replace this with use of the error(3) function: if (something_bad) error (EXIT_FAILURE, errno, ...); The error(3) function is supplied by glibc, or by gnulib on platforms which don't have it, and is much more flexible than perror(3). Since we already use error(3), there seems to be
