I guess you are looking for something like this http://traffic.comics.unina.it/software/ITG/ D-ITG (Distributed Internet Traffic Generator) is a platform capable to
produce traffic at packet level accurately replicating appropriate stochastic processes for both IDT (*Inter Departure Time*) and PS (*Packet Size*) random variables (*exponential, uniform, cauchy, normal, pareto, ...*).

So that it is possible to create catchy plots. :)"what metrics" you want to collect and how to you want to see it would dictate which apps you'd be using - tcp queue/buffers - dropped packets - delays - retries - udp vs tcp vs icmp vs ... - stuff ... xmit/recv buffers in the hardware, default buffers in the OS and buffers in the software apps must all be tuned to the same gigE or 10gigE speeds otherwise, whacky stuff will happen for "catchy plots", you'd want gnuplot so you can (infinitely) zoom in into the section you want to see dot-by-dot for big picture ... netstat, ntop, (not much info) mrtg, etc, etc big list of apps Packet-Craft.net/AppsAny hints or links would be greatly appreciated.if you're a proficient python'er, you'd probably like scapy which can do everything you'd need to customize any packet magic pixie dust alvin # # Packet-Craft.net/Apps #
