Poate mai intereseaza pe careva ... -- Attached file included as plaintext by Listar -- From: Werner Almesberger <[EMAIL PROTECTED]> Subject: New toy: tc simulator Date: Sun, 28 Jan 2001 16:06:05 +0100 To: [EMAIL PROTECTED], [EMAIL PROTECTED] MIME-Version: 1.0 I've written a little package that allows experimenting with Linux traffic control entirely in user space. This is useful for configuration testing, traffic control element development, debugging, and simulations. Right now, the simulator is very basic, but it'll be easy to add new capabilities. It works as follows: the kernel traffic control code is compiled in user space and linked against iproute2/tc and some glue code. This way, the original tc code can be used for configuration. The glue code provides the netlink communication from tc to the "kernel" code. Afterwards, a simple event-driven simulation can be run on that configuration. Note that the classifiers "fw" and "route" don't work, because neither firewalling nor routing are included in the simulator. Also, the ATM qdisc isn't supported. The current version is in: ftp://icaftp.epfl.ch/pub/linux/tcng/tcsim-0d.tar.gz It requires a 2.4.0 kernel source tree and iproute2 991023 or 001007 (probably works also with all the iproute2 versions in between, I just haven't tried them). Also, I haven't done much testing yet, so there are probably several nasty bugs in addition to the long list of known bugs. I won't announce each little update, so please check for new versions every once in a while if you're using tcsim. - Werner -- _________________________________________________________________________ / Werner Almesberger, ICA, EPFL, CH [EMAIL PROTECTED] / /_IN_N_032__Tel_+41_21_693_6621__Fax_+41_21_693_6610_____________________/ --- Send e-mail to '[EMAIL PROTECTED]' with 'unsubscribe rlug' to unsubscribe from this list.
