similar to: Can I use sk_buff->cb in Qdisc?

Hi, I''m adding a queuing disc. inside kernel. I am confused that it seems few other qdiscs allocate memory dynamically. Is it invalid to use memory calls like molloc or just a suggest that do not use it often? Thanks for your help. bon ----------------------------------------------------------------- < 每天都 Yahoo!奇摩 > www.yahoo.com.tw

Hi, all I am interested in Linux related QoS, especially PRIO queue discipline (qdisc). I test some experiments about PRIO qdisc. Host A ------ Router A --- Router B --- Host C | 1Gbps | Host B ---------+ +-------- Host D flow 1 : Host A -> Host C (TCP) flow 2 : Host B -> Host D (UDP) priority 1 queue (pfifo, size 1000 packets ) : flow 1 priority 2

hello, this is my new qdisc patch, when i recompile the kernel with this patch i dn''nt succeed please look at it and if there are any mistakes plesease send me a mail thanks in advance ___________________________________________________________ Do You Yahoo!? -- Une adresse @yahoo.fr gratuite et en français !

Hello! I like to announce sch_ooo, a new queue discipline that, attached to a class (or a device, as root) reorder the packets that pass by delaying some. Example: tc qdisc add dev eth0 root ooo limit 100 gap 4 wait 1100 This queue will create a pfifo with limit 100 and will delay every 4th packet with 1100ms. An stream of 6 packets like this: 1 2 3 4 5 6, generated by ping will be reordered

i have a question with queuing discipline " if i create many classs with sfq and cbq and ... i would like to know about qos . which queuing discipline will be chosen first. ( not use priority ) (queuing discipline) sfq---------> packet incoming packet outgoing cbq--------> Thank you .

I want to implement a new queuing discipline for the tool tc. The new queuing discipline would support the application of multiple threads on the same queue with different kinds of traffic. Each kind of packet will have its own drop probability but while calculating the average queue length, the no. of packets in the queue will be equal to the sum of the individual no. of packets(of the different

Dear LATRC and devotees, I have developed some Linux queueing disciplines. I developed them for my masters project. You are free to use or distribute my work. Here is the abstract from my dissertation:- This is a project to implement a Mice and Elephants queuing discipline on Linux. My project has three aims. The first aim was to produce a prototype Mice and Elephants router

Hello, I''am successful using a linux (2.4.20) bridge and the cbq.init_v0.7 script for traffic shaping. But I can only use the queuing discipline tbf (LEAF=tbf). If I try use queuing discipline sfq or none then tc applies the rules but no shaping occurs. Is this problem a normal behavior when using bridging ? I tried to use htb.init (using patched tc binary). It accepts the rules but

hello folks, this is my first post to that list. so I hope I am not completely OT here :-) reading the (excellent!) lartc and then writing my own qos-script I have still some open questions which I will try to formulate now: - "Now we can optionally attach queuing disciplines to the leaf classes. If none is specified the default is pfifo." - I can''t find info about Pfifo.

Hello mailing list, I don´t know how to use HFSC queuing discipline with tcng configuration language. I become always this error: syntax error near "hfsc" Is it possible, that tcng provides no support for this classful hfcs queuing discipline? Please help! thanks ----------------------------------------------------------------------------

hi, I am really a newbie in linux traffic control.But i have task to implement a tool similar to the nistnet tool used for netwok emulation tests but which emulates a wireless environment. I was exploring the use of the traffic control subsystem for this task.In this regard i have a few questions i need to post in order to clarify my thoughts on how to do this.I am using tcng to classify

Hello Lartc''s users, This is my first contact. I''m trying to implement a new queue discipline based on bfifo schedule. I search on internet but there are some problem(s) that I don''t Know how to solve them and that''s why I''m here asking for your help. Well, These were my steps for the implementation: - Put the new qdisc routine

Okay, here is a very simple QOS scheduler that delays packets for 2.6. It is good for testing, and might be useful for people who want to put some class of traffic into a "penalty box". Alexey''s tc command is really easy to extend to new disciplines. There is a version which knows about this scheduler at: http://developer.osdl.org/shemminger/tcp/iproute2-delay.tar.bz2 The

Hi there, Being a strong believer in "There is no such thing as a stupid question", here comes nothing... At the moment I am working my way through the "HTB Linux queuing discipline manual - user guide" and I have a question... I implement the tc commands using a simple bash script. But I have yet to find a way to adjust the settings. Whenever I do "tc filter del dev

Hi, Has anyone used TC in a wireless environment, which is dynamic. I understand that the parameters for queuing are static and cannot be changed unless the queuing discipline is deleted and reloaded with different parameters. If anyone can share any experience, that would be helpful. Thanx. Azim. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

Hi all, I''m sure I''m soing something wrong here. I am trying to set up a rate limit inside another rate limit. eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so that packets passing through the bridge are counted at each port.(ie the throughput is limited to 512K, not just the traffic in one direction.) This part works OK, but I also want to limit a

Hello, I was attempting to throttle egress traffic to a specific rate using a tbf. As a starting point I used an example from the LARTC howto, which goes: tc qdisc add dev eth1 root tbf rate 220kbit latency 50ms burst 1540 I then attempt a large fetch from another machine via wget (~40 megs) and the rate was clamped down to about 12Kbytes/s. As this seemed too much, I gradually increased
