  3. 2. At least one Network OSprobably many.Open- and closed-source 3. Well-defined open API Software Defined Network 1. Open interface to packet forwarding Feature Feature Network OS Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding

  4. My goal today Show two examples of research demos on top of OpenFlow/SDN

  5. Experimental Setup Experiment Network OS: NOX Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding

  6. Experimental Setup with Slicing Experiment Experiment Experiment NOX NOX NOX Experiment Network OS: NOX Slicing Layer: FlowVisor Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding Packet Forwarding

  7. Research Example #1Load-balancing as a network primitive Nikhil Handigol, Mario Flajslik, Srini Seetharaman

  8. LOAD-BALANCER

  9. Load Balancing is just Smart Routing

  10. Nikhil’s Experiment: <500 lines of code Feature Feature Network OS: NOX

  11. Research Example #2Using all the wireless capacity around us KK Yap, Masayoshi Kobayashi, Yiannis Yiakoumis, TY Huang

  12. KK’s Experiment: <250 lines of code Feature Network OS: NOX WiMax
