  1. GENI Research and Educational Experiment Workshop Panel Kuang-Ching “KC” Wang Holcombe Department of Electrical & Computer Engineering Supported in part by NSF grant CNS-094408

  2. Future Internet: My Interests • Ubiquitous Future Internet = Computing + Connectivity + Clients • Reliable • Secure • Performance • Information, context-centric • Customization Nov 18 2010

  3. GENI and OpenFlow at Clemson Infrastructure • OpenFlow campus Ethernet and wireless mesh network • GENI computing racks • WiMAX base stations • NetFPGA lab GENI experimentation grants • Mobile gigabit wireless access (with P. Ramanathan, UW-Madison) • Security and traffic analysis (with R. Brooks) • Data sharing over heterogeneous networks (with H. Shen) Nov 18 2010

  4. GENI Programmable Wireless • GENI Cognitive Radio • Clemson partners with Rutgers WINLAB on remote experimentation framework • GENI Open WiMAX • GENI is developing campus kits for deployment at universities May 20 2010

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

  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 Our 3D movie needs 10 Mbps Legacy Internet vs. SDN Perhaps + in-network caching I want to watch 3D movie from Hulu I am a mobile node & support ad hoc mode GENI Research and Educational Experiment Workshop, Mar. 16 2012

  7. Clemson’sSteroid OpenFlow Service (SOS) Experiment SOS pipe SOS agent SOS agent Optimized Protocol Optimized Protocol Legacy Protocol Legacy Protocol OpenFlow switch OpenFlow switch User Application User Application SOS OpenFlow Controller GENI Research and Educational Experiment Workshop, Mar. 16 2012

  8. Nationwide Dual-path Experiments GENI Research and Educational Experiment Workshop, Mar. 16 2012

  9. On-Campus Experiments • Four OpenFlow switches on campus recreate nationwide topology. • tc (netem) software to emulate different network characteristics (latency, bandwidth, loss). • Measure at different points in network: iperf, tcpdump/wireshark, switch statistics, ping, … Indigo HP HP Indigo GENI Research and Educational Experiment Workshop, Mar. 16 2012
