Hysteresis modeling and simulation
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...

[PATCH 0/2] Runtime configuration of HTB''s HYSTERESIS option
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 t...

HTB dequeueing in pairs fixed
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. ______________________________________________...

gypsy, and not only
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

[Bug 799] scp incorrectly reports "stalled" on slow copies
...ot.org ReportedBy: peter.jeremy at alcatel.com.au The following description relates to OpenSSH 3.5p1 as embedded in FreeBSD/i386 4.9p1. The overall behaviour (incorrectly reporting "stalled") is identical on OpenSSH 3.7.1p2 and a quick check shows that the scp blocksize and ssh hysteresis behaviour have not changed. I believe the behaviour is not platform or OS dependent. By default, scp(1) will provide a progress meter showing the transfer ETA. If the link is slow, the transfer meter will alternate between displaying "- stalled -" and unrealistically short ETAs even th...

Strange pings.
Hi. The configuration script is at the bottom. My configuration looks similar to this: imq0 | 1:1 (12mbit) | 1:2 (10mbit) | 3:0 | 3:1 (256kbit) / \ 3:2 3:3 icmp (rest) both 3:2 and 3:3 have rate 1kbit ceil 256kbit Icmp bucklet have priority 1 (better), "rest" bucklet have prio 2 (worse) I tested the script with heavy download

Recommended minimal amount of free space to keep?
...ormance too much. I guess that having a filesystem 99% full will create too much fragmentation and many other issues, but having them only 30% full seems like a waste. Currently I try to keep them at 70% full utilization but I have not based that on anything just guess. So, what % hysteresis do you recommend? For example, when they get 70% full then grow them so that they get 50% full? Other values? Thanks for the hints!

UPS restart delay
...ile I was testing it I found that it would turn back on straight after power was restored. I had a look but I couldn't find a setting which would let me tell it to charge to (say) 50% before turning the load back on. Does anyone know if this is possible? A setting like this would provide some hysteresis for successive power failures which would be handy to have :) Thanks. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerp...

speex preprocess redux

HTB and PRIO qdiscs introducing extra latency when output interface is saturated
Im using a Linux machine with standard pc hardware with 3 seperate PCI network interfaces to operate as a DiffServ core router using Linux traffic control. The machine is a P4 2.8ghz, 512mb RAM running fedora core 3 with the 2.6.12.3 kernel. All links and network interfaces are full duplex fast ethernet. IP forwarding is enabled in the kernel. All hosts on the network have their time sychronised

Re: Is this actually possible?
...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://mailman.ds9a.nl/mailman/listinfo...

HTB is being hang my computer :/
What''s wrong... I have Celeron 633MHz nd 768Mb RAM. When I''m running my script everything is OK, but when I''m connecting Internet and LAN link computer is hanging. But when i dissconnect this everything is OK. I have 500 users, 1500 classes and 3000 filters. Is it normal? What should I do?

Re: [Iaxclient-devel] iaxclient & speex
...nformation you want: (a) the actual signal energy before processing, and (b) VAD decision. You might be able to fake it good enough by putting AAGC before AEC, and using the VAD decison from frame "n-1" when you're processing frame "n". You'll probably have enough hysteresis and a bit of history in the decision making process anyway that it might not matter. As far as gain changes messing up the rest of the preprocessing chain: It would seem to mess up the denoiser, the VAD logic, etc., as well as the echo canceller. It might be possible (as I wrote earlier) to...

bandwidth control on htb
Hi, I implemented queues on some ports with htb by filtering. and to have a constant bw, i defined rate and ceil the same. But while watching the bw''s, I ve realized they may sometimes exceed the defined value for short periods. How could I avoid this situation? I thought that implementing a leaky bucket''d be fine but i m not sure about this and how to do it on tc. I would be
