5. Three Typical Questions from/to Experimenters Rosen, Wang Clemson University GENI Research and Educational Experiment Workshop, Mar. 16 2012 5 What can GENI do? What do you want to do? How should you use it (meaningfully)? Proposed Approach Problem Formulation Experiment Design Hosts,storage Network Entity: Application? Protocol? Middleware? Goal: Get performance on real network Pick interesting scenario Identify GENI resources Pick or design protocols (including those you normally don’t care!) In-network processing Instrumentation (measurement tools) Real traffic create DDoS

6. An Example Key features: – End hosts to emulate video server, video clients – Legacy or OpenFlow switch in network backbone and edge network – Agent hosts next to network switches – Mobile ad hoc network testbed Rosen, Wang Clemson University GENI Research and Educational Experiment Workshop, Mar. 16 2012 6 I want to watch 3D movie from Hulu Our 3D movie needs 10 Mbps Legacy Internet vs. SDN Perhaps + in-network caching I am a mobile node & support ad hoc mode I am a mobile node & support ad hoc mode
