QUESTION :
I’ve looked at this already: How to deliberately introduce a delay for incoming UDP packets
I am testing a server-client system, and need to delay messages from the server to the client by some specified delay — say 1ms. I don’t want packets in the other direction to be delayed.
Some sort of proxy software is completely acceptable. Any suggestions for windows?
ANSWER :
WANem (http://wanem.sourceforge.net/) is a liveCD linux distro that let’s you manipulate traffic on the wire. You can limit bandwidth, introduce lag, jitter, lost packets, and a bunch of other cool things.
Just boot it in a spare PC or VM and create routes on your client and server and you’re all set.
