Network restructuring Feature Network OS Feature OS Feature Custom Hardware Feature OS Custom Hardware

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

My goal today Show two examples of research demos on top of Open. Flow/SDN

Experimental Setup Experiment Network OS: NOX Packet Forwarding Packet Forwarding

Experimental Setup with Slicing Experiment NOX Experiment NOX Slicing Network Layer: OS: Flow. Visor NOX Packet Forwarding Packet Forwarding

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

LOAD-BALANCER

Load Balancing is just Smart Routing

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

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

Feature KK’s Experiment: <250 lines of code Network OS: NOX Wi. Max
