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

2 Future Internet: My Interests Ubiquitous KC Wang, Clemson UniversityNov Reliable Performance Secure Information, context-centric Customization Future Internet = Computing + Connectivity + Clients

3 GENI and OpenFlow at Clemson Infrastructure – OpenFlow campus Ethernet and wireless mesh network – GENI computing racks – WiMAX base stations – NetFPGA lab KC Wang, Clemson UniversityNov 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)

4 GENI Programmable Wireless GENI Cognitive Radio – Clemson partners with Rutgers WINLAB on remote experimentation framework KC Wang, Clemson UniversityMay GENI Open WiMAX GENI is developing campus kits for deployment at universities

5 Three Typical Questions from/to Experimenters Rosen, Wang Clemson University GENI Research and Educational Experiment Workshop, Mar 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 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

7 Clemson’s Steroid OpenFlow Service (SOS) Experiment OpenFlow switch OpenFlow switch SOS OpenFlow Controller SOS agent SOS agent SOS pipe User Application Legacy Protocol User Application Legacy Protocol Optimized Protocol Optimized Protocol Rosen, Wang Clemson University 7 GENI Research and Educational Experiment Workshop, Mar

8 Nationwide Dual-path Experiments Configuration TCP Planetlab (Mbps) TCP Protogeni (Mbps) iperf UDP (Mbps) SOS Protogeni (Mbps) Path 1 (short) Path 2 (long) Multipath 639 Rosen, Wang Clemson University 8 GENI Research and Educational Experiment Workshop, Mar

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 Rosen, Wang Clemson University 9 GENI Research and Educational Experiment Workshop, Mar

10 FURTHER QUESTIONS Rosen, Wang Clemson University 10 GENI Research and Educational Experiment Workshop, Mar LET THE FUN BEGIN!
