similar to: qdisc monitoring

I have made a tool to have real time plots of enqueues, dequeues, drops, size of queues, and time duration in queues with a tcl-tk interface, it it availlable at http://rawsoft.org/ I would be happy if somebody tried it. Note: for the tool to work, you have to compile 2 kernel modules, so you have to have the kernel headers. If you try it, please send a message to

Hi, Actually, I did some modification on sch_fifo.c to do some required accumulation of packets lets say 300 packet and to dequeue them together but I couldn''t compile the modified fifo, the question is How can I compile and to test my modified fifo. Thanks in advance for your reply and help _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

Hello, The qdisc spy has evolved, the new version can spy on udp and tcp connections, the results are displayed upon command. There is no gui for this tool yet, but I will try to make one. If you want to try: http://rawsoft.org Vincent Perrier

With the advice of Thomas Graf, I have modified the qdisc monitoring tool. A new qdisc called spy can be gafted in any qdisc tree and bring back detailled information that is shown with curves. Try it if you want real time visualisation of enqueues, dequeues, delay in queue, queue size. It is at http://rawsoft.org Vincent. _______________________________________________ LARTC mailing list /

How can I advertise a free software that is associated to the linux qdiscs (more particularly htb). The soft does not seem to have impressed google, it is at http://www.rawsoft.org If you work on htb and are used to compiling modules, then you should try it. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc

Hi all I have a trouble configuring the qdiscs, when I indicate the "perturb 10" option to tc, i gives me this error: tc qdisc add dev eth0 parent 5:1323 handle 1323 sfq perturb 10 RTNETLINK answers: Invalid argument if I don''t put the "perturb 10" option, it works. another question is about iptables, when I indicate the " --set-mark" option: iptables -t

HTB versus HFSC, both qdisc offer the same kind of service, if you want to see comparative test results, go to http://www.rawsoft.org at the line "TEST RESULTS" you will find the results for a sharing test and a burst test. You will see that both qdisc are good. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

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 !

I have a router with 3 network interfaces like in the following ASCII diagram below. All interfaces are 100mbit. There is tcp traffic being sent from net1 to net3 and from net2 to net3 and the tcp connections consume as much bandwidth as possible. There is a pfifo queue on the egress interface eth0 of the core router with a limit of 10 packets. net1 --> (eth1) router (eth0) -> net3

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

I think that there are no qdiscs that permit to drop the oldest frame of a queue when this queue is full, but I would like to be wrong: bfifo drops arriving frames when the max queue length is reached. red also drops arriving frames in a more elaborate fashion, with a drop probability that increases above a limit and becomes a drop certitude when the max queue length is reached. sfq drops

A new interface and qdisc monitoring tool called kernel2web is available http://rawsoft.org. Note: you have to compile a kernel module for kernel 2.6. Vincent Perrier.

Hi All, I found 2 unusual behavior with u32 classifier in Kernel 2.4.12. I’ve u32 compiled as module. 1> u32 filter seems not working if there is already some fw filter used for some other class. In order to get u32 working I’ve to delete root class, which in terms delete all fw filters too, and then same command for u32 works. fw is also compiled as module. 2> If I add u32 filter to my

hi i wanted to get the qdisc stats without using tc. is this possible by just using rtnetlink sockets directly? if possible could someone point me to an example. thanks. __________________________________ Do you Yahoo!?

Hi all. I''m quite new to the concepts of the "traffic control" framework, and I''ve got a programming-related question. Hopefully someone has the answer... Is it possible, either for the device driver itself or for a userspace program, to get information about how many packets are currently queued for a given network interface? Let''s describe it a little

hi all, i want to try htb3 with imq downloaded & patched imq & htb3 with kernel-2.4.18 on rh7.2 but got STUCK on step 1 :( this are what i did can anyone guide me what went wrong on the first step itself !!

There is an design problem with the qdisc interface that causes qlen related bugs in netem, tbf, and other qdisc''s that peek at the top of the queue. The problem is that requeue needs to be called from the dequeue function but requeue can fail. If requeue fails, then the calling qdisc can not properly handle the error. If it returns NULL, then the parent''s expectation about qlen

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
