10ms interval fping data
I had been attempting to simulate what a 10ms rtp stream would look like. So I ran fpings of 220 bytes over a 10ms interval while loading up the system. fping, nor ping, allow you to go at intervals of less than 20ms as a normal user. Secondly, systems contain optimizations for ping and what I need to find is something that tests an actual rtp stream (or streams). I came up with a good one - using the linux audio system to play back a sound file over rtp, which in addition to being useful, gives me some music to listen to, AND immediate feedback as to whether something is working well or not. This also lets me fiddle with multicast again. This commit is useful mainly for some improvements in how I constructed cdf plots in gnuplot.
