Hello Folks ,
I am trying to test TCP throughput with different variables. I want to
simulate a delay of aprox 45msec between two test PCs connected two
bat to back routers . How do we introduce an artificial delay where in
the actual delay is on 2-3 msec.Using cisco routers.?
Google 'dummynet'. FreeBSD with Dummynet does this nicely. If you really
want it transparent, you can build a dummynet machine with 2 NICs and do
it in bridged mode. You can play with bandwidth, delay, introduce packet
drops etc.
