similar to: [PATCH 1/2] Runtime configuration of HTB''s HYSTERESIS option (kernel)

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/ ),

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 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

hello Dirk, thanks for the info. Sorry, im new to the Linux World. I just wanted to ask, will the samba2.....that comes with my RedHat9.2 installation work for what I want to achieve(to connect my LinuxPC to my Windows PC so that I can exchange files between the two?) - im asking so that I dont uninstall Samba2 and begin to have problems installing the new version. Also, you said "it has

Hi, I have a Debian based NAT router. How can I manage upstream egress bandwidth based on the LAN ipadress in the network below?

Hello I''ve set up a simple system. It seems to work for a short while, but now I''ve got batches of 100''s of these messages. Also I can''t connect through that box any more. It''s as if forwarding died. Has anyone any advice? Regards John

The delay scheduler dequeue routine has some code cut&pasted from the TBF scheduler that caused a race with E1000 when ring got full. It looks like net schedulers should never be calling netif_queue_stopped because the queue may get unstopped by interrrupt or receive soft irq (NAPI) which races with the dequeue in the transmit scheduler. Also, if requeuing the packet fails, it is probably

Could someone tell me how to end the trouble I'm encountering when running latex on the .tex file produced by Sweave()? Sweave() seems to process the example file (http://www.ci.tuwien.ac.at/~leisch/Sweave/example-1.Snw) without problems, and the file example-1.tex produced is the same as in the Sweave manual. However, when I run latex on example-1.tex, many error messages and requests for

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

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
