I work in THALES on the implementation of qos on linux embedded
routers. I needed a tool to qualify the qdiscs implemented in the linux
kernel. As I have not found it, I made one based on tcl-tk. It gives a
real time visualisation of all the parameters of the queues, (enqueues
dequeues drops and time duration in queue) with tcl-tk plots refreshed
every second. The implementation is based on a slight modification of
the leaf qdisc used, (red qdisc in my case), a module in the kernel
(based on a character driver) that communicates all the results every
second to the user world, a daemon server in user space that receives
the results and communicates them to the end client through a tcp
socket. The end client is an association of C and TCL-TK software. This
permits a remote visualisation of an embedded system's qdisc. I would
like to participate to the linux community, and give what I can, How do
I proceed? Note: I have only tried HTB so far, but I will try HFSC soon.
