1. HFSC have 4 curve such sc, rc, ls, ul and 1.1 In leaf class can specify rc for guarantee service (bandwidth and delay) and If want to sharing fairness exceess service, we must specify ls and ul curve too (ls curve with paramater m2 specify at lease sharing bandwidth in that class will receive and ul curve mean maximum bandwidth in that class will receive) so i''m doubt .. about if i

Hi, I have to port ALTQ(Alternate Queueing) software form the FreeBSD to QNX. It''s more like a bandwidth manager. Since I am new to this domain, any kind of help will be useful. I have many doubts like * What exactly is a bandwidth manager * Where will it sit in the OS * How will it be implemented. Thanks in advance Prajith.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings all, Working in concert with the original authors, Klaus Rechert and Patrick McHardy, I have translated their article "HFSC Scheduling mit Linux" [0] on Hierarchical Fair Service Curve (HFSC) into English [1]. http://linux-ip.net/tc/hfsc.en/ Although the original content is not available directly from their website,

Hello All, I am trying to prioratize VOIP traffic from data. The follwing link says that HFSC is better than HTB for shaping VOIP traffic. http://www.voip-info.org/wiki-QoS+Linux+with+HFSC I am in search of good documentation to start with HFSC, I am unable to understand the parameters used. I "googled" a lot to find on how to use HFSC, but no luck. Can anyone of you get me a link To

Hello I''ve been messing with traffic controlling for some time and encountered singularities I''d like to talk about. First explaining of my pow (can''t tell how much each point is relevant) Box with Debian, Intel PII*2 old and fancy:), ADSL link with dyn IP, some servers (f. ex. squid), loc net with dhcp, (although IP statically given by MAC); MASQ. Such circumstances

I'm having problems getting PF + ALTQ to work on em(4) interfaces under 8.0-RELEASE. Kernel was rebuilt with the additional options necessary for ALTQ and what not. Same basic configuration works fine under 7.2-RELEASE. Basically, the queues create successfully but running a pfctl -vsq shows a zero packet/byte count for all queues, even the interface's root queues. This same problem is

I''m using HFSC to limit bandwidth for our wireless customers. However, I''d also like the bandwidth prioritized based on packet type. This is what I''m trying right now, and I''d just like some input from anyone out there knowledgeable in this on whether it does what I want it to do: Eth1 -> HFSC ........|-> HFSC (User1) (Min 512 Kb, Max 1024 Kb, Burst 1536

I've got a HP dv8000 laptop. Setting up the wpi driver for wireless freezes the system on boot with the following error: wpi0 requested unsupported memory range wpi0: could not allocate memory resource It lists a pcbi device (pcbi4 i think) and an actual memory range, but since I have to reboot using kernel.old the /var/run/dmesg.boot is wiped with the info. Is there anyway to grab the

Hi all :) I''ve tested this and having a cpufreq that slows down the CPU affects the rate of HTB. My ondemand cpufreq governor scales down the CPU frequency about 40% and this is more or less the slowdown the rate suffers, 40%. Any known way of dealing with this without having to disable cpufreq?

Hello Dear List members, as you can see (and guess) from the code below adaptIntegrate(f,lowerLimit=c(-1,-1),upperLimit=c(.9999,.9999)) $integral [1] 9.997e-09 $error [1] 1.665168e-16 $functionEvaluations [1] 17 $returnCode [1] 0 > adaptIntegrate(f,lowerLimit=c(-1,-1),upperLimit=c(1,1)) the last command runs for 45 mins now. -this one takes only less than sec:

I want to measure the error in the estimation of a 2 dimensional density function that is calculated using an integral but run into problems trying to integrate with adaptIntegrate because the integrand also calls the function adaptIntegrate. In particular I want \int \hat{f}(x,y) - f(x,y) dx dy where \hat{f}(x,y) = \int K(a,b, x, y) da db and in this simulation study I know what the true value

Hi, I am using adaptIntegrate from Cubature to do numerical integration on a double integral with a 1 x 2 vector x. Say the function is something simple to start like f(x)=x1*x2 and I wish to integrate x1 over (0,365-x2) and x2 over (0,365) f <- function(x) {(x[2])*(x[1])} # "x" is vector int1<-adaptIntegrate(f, lowerLimit = c(0, 0), upperLimit = c(365-x[2], 365)) I recieve
