Hey,
I wanted to try the netem extension to setup a loss via Gilbert,
Simple Gilbert, Bernouli loss model[1]. Kernel support is included
since several releases. But configuration as demonstrated in [1] does
not work at all. It seems that the userspace part in iproute is
missing, the original patch from the authors does not work.
Does anybody know about that?
Bye, Marcus

Hi
Stephen Hemminger did the kernel part last February (commit 661b79725
netem: revised correlated loss generator)
But apparently never committed the iproute2 part.
Stephen ?

I just wrote, tested and support for the loss model parameters
in iproute. Check the latest checkin in the git repo. Also the man
page has been fixed to reflect the implemented options.
