    4 [[Image(25.png, 120, nolink, right)]] 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.

    66The 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.
