This document provides an outline for a workshop on open networking and SDN. It begins with an introduction to open networking and SDN, then discusses using Mininet for network simulation and the ONOS SDN controller. It provides background on the presenter and their work in SDN areas like OpenFlow and P4. The document explains concepts like the benefits of SDN, the decoupling of the control and data planes, southbound protocols, and how OpenFlow works. It also discusses options for learning SDN hands-on using software switches, hardware switches, network simulators, and SDN controllers.

6. Legacy network….
• High CAPEX
• Expensive !!!!
• Hardware, Software, Solution !!!!
• Lots of time
• Livers.......

7. Legacy network….
• High OPEX
• Lots of hardware -> Lots of protocols
• Hard to trace error
• Livers…….

8. Open Networking & SDN
• Open, Standard network control method
• Reduce cost (white box switch)
• Reduce CAPEX & OPEX
• High flexibility
• Easy to control network(s).

9. How SDN works?
• Decouple Control and Data planes.
• Switch become stupid.
• Centralize network intelligent.
• Network infrastructure is abstracted from the
applications.
