I need to be able to simulate high bandwidth/high latency/high packet loss on my pc for the purpose of testing the software that I'm writing.

I've seen some software that you can install on a separate machine that will act as a throttling router/gateway but 1) I didn't really trust the companies that I found 2) A separate machine isn't available atm.

I was talking to the network admin and he told me that he has heard of software that will throttle my own NIC (he didn't mention packet loss/latency though). Is anyone aware of any software that can do this?

I am asking this on SO as well.

This was asked (kinda) on SO before. The question was asking for a Firefox plugin, which we later found that Firefox Throttle could simulate slow internet speeds. Several other options were given also - the author of the question specifically desired a plugin, which is why the plugin was accepted as opposed to an alternative.

+1 - from the link, Charles looks like what I'm looking for I'm going to check it out. Thank you. – SnOrfus Aug 5 '09 at 20:07

If you're using linux you can use trickle, which will do what you want.

+1 for the recommendation. I am, however, using windows. Updated the tag. – SnOrfus Aug 5 '09 at 19:33

Never used it personally but I remember a sale guy telling me that VMWare Workstation could do this so you can simulate slow performance and multi OS etc when testing.

A cellular card should do this quite well ;)
