  4. 4. • NOX Classic  NOX was programmable in C++ and Python • NOX [NEW fork]  C++ Only  Remove Python from NOX: “New”NOX • POX  Python only  Build a new platform in pure Python  Target Linux, Mac OS, and Windows  Good for research NOX & POX CONTROLLER About NOX & POX 4
  5. 5. • NOX was the first SDN controller • Linux • C++ and Python • Component system • Event-based programming model • OpenFlow interface • Packet construction/dissection libraries • Applications: Forwarding (reactive), topology discovery, host tracking,… NOX • A Java-based OpenFlow Controller(forked from Beacon) • Apache Licensed • REST API • Pure java(no OSGI know how required) • Dead simple to build and run • Tested and hardened in real environmets Physical OpenFlow switches and real networks Code included in commercial product from Big Switch Networks Floodlight About NOX & Floodlight 5

  9. 9. 9 1. Displays and Refresh Network status 2. Display NOX Console log 3. Show Switch status (Flow , table, Aggregate statistics) 4. FlowManager A. Add/Del/Change Flow Table B. Get Switch info C. Get Flow table list D. Profile list 5. Flow Trace 6. OpenFlow Switch Specification Version 1.0.0 ktds Open Flow Controller Support
  10. 10. 10 1. Test 환경구성 (MININET) 3 hosts – 4 switch topology 2. Ping test A. H1 ping H7 B. H2 ping H7 3. Packet 경로 및 Flow table 확인 4. Change H2 <-> H7 path by Flow modification 5. ADD Flow table on Switch 3 (change outport! Which IP is H2) 6. Check H2 ping H7 ping status! 7. Add flow table on switch 5, and switch 6 8. Now ping works! We will change Data path by Flow modification Test Scenario
