Demonstration

Experiment 1: A Simulated Dumbbell Model • Develop network model in Java • Create experiment • Inspect and change network configurations in the attribute tree and the python console • Launch experiment on local host • Visualize traffic flowing on the network

Experiment 2: An Emulated Campus Network Model • Generate/compose large networks • Specify emulated hosts/routers • Set up execution environment (using a preallocated Proto. GENI slice) • Launch experiment on the Proto. GENI slice • Create emulated traffic (traceroute, iperf) • Monitor real-time traffic using Live. Graph

Experiment 3: HTTP Client Cloud • Set up and run Apache server on a real node • Create a campus model for simulated clients • Specify stochastic HTTP requests (from simulated client to real server) • Observe data transfer using tcpdump and from server log
