I''m grappling with a problem that looks like sfq is not working (packets don''t get fairly queued, they appear to be always sent FIFO). My configuration appears to be correct. The machine is running quite an old kernel and if I could convince myself that the sfq code it has is just broken, I''d spend the time to upgrade it. Is the...

Hello guys I have a subnet with 255 users, which need to share 1 single slow internet connection, so i would like to implement a kind of *fair queuing *on the UPLOAD between them, which means that they all share the connection equally.. The tools that i have available is: A linux box with IPROUTE2,HTB and TC.. I have looked at some examples, and my first idea was to make 255 entries in

I'm sure I'm being stupid so flame away... R2.2.1 on Windoze (boohoo) latest updates of packages. I'm exploring a dataset (land) with three variables looking at an narrowly unbalanced two group (GROUP) ANCOVA of a randomised controlled trial analysing endpoint score (SFQ.LOCF.ENDPOINT) entering the baseline score (SFQ.BASELINE) as covariate and the following work fine: > res.same <- lm(SFQ.LOCF.ENDPOINT ~ SFQ.BASELINE + GROUP,land) > res.diff <- lm(SFQ.LOCF.ENDPOINT ~ SFQ.BASELINE + GROUP + SFQ.BASELINE*GROUP,land) > anova(res.same,res.diff) I try:...

Can I use the same SFQ queue dicipline for all the classe in a CBQ or HBT system?

Hi all. I have a bridge running Linux 2.4.24 that I use as a bandwidth manager on a broadband wireless network. I''m using HTB and SFQ to prioritize that share bandwidth on a per-cell basis. My IP tables rules divide the traffic based on IPand traffic type (using layer-7 filter and ipp2p). My goal is to make sure that p2p traffic on the network doesn''t sink all of the bandwidth and affect the performance of high-priorit...

Anyone notices that using sfq qdisc adds latency compared to pfifo? With "sfq perturb 10" ping latency is around 100-120ms, while with "pfifo limit 3" drops to ~10-30ms (qdiscs belong to htb class). I''m missing something or is this expected? { $TC_CLASS parent 1:1 classid 1:20 htb prio 0 rate 90...

...some user are browsing weight pages, or when 2 or more users are downloading at the same time, I cannot get VOIP to work properly, because quality becomes very poor. I have made all kind of imaginable test, probes and combinations, trying to test with different burst values for classes, attaching sfq qdiscs to all leaf classes, then only to surfing classes, then only to VOIP classes, and even, gaming with R2Q/Quantums, that would not be necessary, because 64Kbit is very more than enough. So please, does anyone have any idea how to completely separate VOIP and SURFING, making 2 independent chan...
