Hi All, I cross compiled and run tc in arm platform. When I tried executing it I got this error. tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 mpu 64 RTNETLINK answers: Invalid argument Is there something I''m missing here...

Hi Stef and Alexey I have read some documents about CBQ algorithm from http://www.icir.org/floyd/cbq.html but still have some question about CBQ in Linux . 1. First estimator can estimate how much bandwidth already USED per class. one estimating algorithm is EWMA (exponential weighted moving average), how about Linux implemenatation about estimator? also do you have link for this algorithm? I

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 find the negative attitude toward CBQ to be distracting and non-professional in the HOWTO. I''ve re-read it for the first time in about a month and comments like "This can be configured in a variety of ways, which I do not understand. Use HTB" do not encourage me about the writer. This is not a personal critique, as I can imagine this being said on a personal website,

Hi! I just recently entered the wonderful world of the so called "advanced routing" and decided to try and limit the bandwidth of a MASQed network here and ended up in trouble :(. The setup is (as far as I can tell) pretty straightforward. eth0 is connected to the "real" network with a proper IP, and eth2 is 192.168.10.x (the MASQed network). All of it is basicly right out of

...far as I can understand, each class can actually contain one _or more_ qdiscs. Furthermore, (at least in the case of CBQ) a class may also contain one or more _classes_ (this really puzzled me. But the HOWTO''s example of a CBQ configuration, and a reading of /usr/src/linux-2.4/net/sched/sch_cbq.c appear to indicate this). (2) In section 9.5.2 ("The qdisc family: roots, handles, siblings and parents"), the HOWTO does not really make clear the fact that some of the nodes in the tree are qdiscs, and some nodes are classes. In particular, the "ASCII-art" diagram does...

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

This patch updates the network emulation packet scheduler. * name changed from delay to netem since it does more than just delay * Catalin''s merged code to do packet reordering * uses a socket queue''s directly rather than layering on qdisc(fifo) because this is used in performance tests. * adds placeholder in API for future enhancements (rate and duplicate).
