Hi All, I'm trying to use Dummynet to test the behaviour of my video streaming application in various network conditions. Dummynet was compiled and installed on an Ubuntu 12.04 box with a 2.6 Linux kernel. I'm experiencing a strange behaviour when I reduce the bandwidth of the link/path. For some reason, instead of having a slow download speed. It seems as if the download is happening in bursts! A portion of the data is downloaded at a high speed, then the data transfer stops for a period of time and then resumes again (and so on). Does anyone have an idea what could be the cause? Or is this even an expected behaviour? If so, why? Thanks, -Ahmed
