I need to test some real time traffic, but I need to create some 'interference' to simulate a flaky internet connection. I am trying to create controlled latency so that I can determine at which point latency (and jitter) becomes a big problem. Would this be a job for QoS?
I've used NIST Net (http://www-x.antd.nist.gov/nistnet/) in the past, and it works well. It doesn't support bridging, however. If you need to simulate flakiness at layer 2 you might be able to use FreeBSD's dummynet(4) driver. Dunno if there's an equivalent Netfilter module for Linux.
