[nsp] I need ideas on how to simulate a 200ms round-trip latency and bandwidth limitation.

[Goldberg Alain (IT)]

Thanks Brian,

I need to conduct all the test localy here, as we want to see the
behavior of rather heavy servers when they are not connected on the same
LAN.
Thank you anyway, I think I'll go for the 
http://info.iet.unipi.it/~luigi/ip_dummynet/

That was suggested.

Thank you all.

I have some routers at the other end of an 800ms link.  What kind of a
test are you going to run?
