Changes between Version 27 and Version 28 of GeniTmix

v27	v28
2	2	Information about Running experiments using the Tmix traffic generation system on ProtoGENI nodes.[[Image(25.png, 120, nolink)]]
3	3	== What is Tmix? ==
4		[[Image(25.png, 120, nolink)]] In order to perform realistic network simulations, one needs a traffic generator that is capable of generating realistic synthetic traffic in a closed-loop fashion that "looks like" traffic found on an actual network.

6	6	The Tmix system takes as input a packet header trace file captured from a network link of interest (such as the link between the UNC campus and the rest of the internet). This trace is reverse-compiled into a connection vector (or cvec) file, which is a source-level characterization of each TCP connection present in the trace. Tmix then uses this information to emulate the socket-level behavior of the source application that created the corresponding connection in the trace. The resulting traffic generation is statistically representative of the traffic measured on the real link.
