similar to: new qdisc visualization tool

Hello, I am interrested in the monitoring of the qos qdiscs parameters such as size of the queue, enqueues, dequeues, delay in queue, I made a tool to have those results availlable at http://rawsoft.org, but it will probably not work anymore because of the kernel evolutions (the file sch_red.c is patched for the tool to work). I would like to have all the necessary data coming from the kernel

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 /

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

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.

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

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

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

Hello lartc I wrote a scheduling qdisc that works on a per-flow basis. It dequeue packets according to a flow interval. But as it turns out there is a problem with it. The qdisc loads just fine and is working correctly. The problem is that if the qdisc is removed and loaded again, it stops responding. By that I mean it stops to enqueue packets to the underlying Qdisc. "tc -d qdisc

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

Hi, Does the ''tc'' tool show dequeue statistics? If so what switches does one use to see this. If not which is the best way to see these statistics? Thanks.

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!?

i doubt about ruleset in mastershaper demo about why use hfsc at leaf class but inner class use htb??? how different for manage traffic like it???? /bin/false qdisc add dev eth1 handle 1: root htb default 1 /bin/false class add dev eth1 parent 1: classid 1:1 htb rate 2048Kbit ######### Incoming Rules ######### chain HB /bin/false class add dev eth1 parent 1:1 classid 1:21 htb rate 128Kbit ceil

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

I''ve been reading the Linux Advanced Routing & Traffic Control Howto and it''s well put together but I''ve a few questions about the mechanism. I dont'' think that I''d have any questions if I just wanted to know how to configure the Shaping method but I''m trying to get into the nuts and bolts. Basically I''m trying to find out the

Hello Mailing list, I have a problem with the prio qdisc and I don´t know what is wrong in my configuration This ist a sample configuration and looks like this: #include "fields.tc" #include "ports.tc" #define X16(i) i i i i i i i i i i i i i i i i dev ppp0 { dsmark { prio(bands 6, priomap X16($be)) { class if ip_proto == IPPROTO_UDP;

Hi, I''m trying to use prio qdisc with htb, however not the "usual" way (like for example FairNAT). Here is my idea: Root has HTB shaping traffic to link speed -> then goes PRIO queues -> each prio queue has HTB with sublasses for each user, should look like this: 1: htb qdisc | 1:1 htb class
