Hi, Is it possible to attach another qdisq under a HFSC classfull ? I try it and the configuraton works : $TC qdisc add dev $dev root handle 1: hfsc default 30 $TC class add dev $dev parent 1: classid 1:1 hfsc sc rate ${RATE}mbit ul rate ${RATE}mbit $TC class add dev $dev parent 1:1 classid 1:10 hfsc rt umax 1500b dmax 30ms rate 200kbi...

Hello everybody, I try to work with TC for a little while in my study and there still are a few questions that I can\''t find any answer anywhere. Firts about qdisc and classes: - What is exactly the difference between qdsic and class ? They are so \"intimately tied together\" that i\''m not sure not make the difference. Why can\''t we have a qdsic HTB with

...0 using HTB? Classes must have guarantied rate calculated from 115kbit possible rate (for example 3 classes) and the possibility to borrow up to 1mbit (depends on ISP side). If it''s impossible, than how to define additional class for excess bandwidth from 115kbit up to 1mbit? Can be other classfull or classless qdisc used in this case? Best regards, Zviad O.

Hi to all of you!!! I am a Computer Science student trying to do the pre-grade thesis. I am trying to develop a free software tool to help administrators to control the traffic. Right now this tool is based on tc and iptables. I am having some problems trying to understand tc and tc examples: - Why in almost every list of tc rules based on htb class, there is a "tc qdisc dev ... root ...

I notice one other small problem with my modified version of SFQ. The fact that packets can be dropped at dequeue time is incompatible with the way HTB (and probably CBQ and others modeled on it) keep statistics. When I fill a low rate queue causing packets to expire and be dropped at dequeue I get interesting statistics like this: This is my variant of SFQ qdisc plfq 8016: dev eth1 ... Sent

Hi, I''m looking for info about IFB devices and how I can use it to incomming traffic shapping. Has IFB any web about it? Do any body known where I can find more info about it? I found this: http://linux-net.osdl.org/index.php/IFB But I can''t stand fine how to use it to allow many ifb''s devices or how to use it with "tc actions". Any help? Thanks --

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

...rned HTB and dsmark. They work properly, but I can''t combine them like this: tc qdisc add DSMARK handle 1:0 ... tc class modify 1:1 ... tc class modify 2:2 ... ... tc qdsic add parent 1:1 HTB ... tc qdsic add parent 1:2 HTB ... -> RTNETLINK answers: File exists Isn''t dsmark classfull? How could I change DSCP field and limit outgoing rate? OK, I can create a HTB "tree" and put a dsmark qdisc at all the leaf classes, but that seems a bit ugly to me...

Can I attach a SFQ qdisc after a TBF qdisc?

Hi all, based on the information in the "Linux Advanced Routing & Traffic Control HOWTO", I was trying to set up traffic shaping on my firewall. While I found the HOWTO very useful, in the process I ran into some problems that I did not forsee: According to the HOWTO it seems that it should have worked, even after spending some time going through the sections looking for answers,

Hi all, I''m having a hell of a time getting my IFB to work. I know I''ve done this before, so I''m missing something stupid. Can anybody tell me what it might be? Configs as follows: -------- #!/bin/sh modprobe ifb numifbs=1000 modprobe act_mirred modprobe 8021q brctl addbr br0 brctl setfd br0 0 brctl stp br0 off brctl addif br0 eth1 brctl addif br0 eth2 ifconfig eth1

Hello What I''m looking for is how to configure the Linux QoS module to do global rate limitation for two (or more) 802.1q pseudo network devices. I naturally suppose there is a possibility with IFB. I don''t want to use IMQ because it''s not integrated to my kernel v2.6.21.1 and I didn''t find IMQ patches for it nor for the iptables package I use (v1.3.7).

Seeing as IPV4 is near it's end of life (http://www.internetnews.com/infra/article.php/3915471/IPv4+Nearing+Final+Days.htm), I'm curios as who know whether everyone is ready for the changeover to IPV6? Is anyone using it in production already, and what are your experiences with it? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog:
