  9. Open Networking Foundation (ONF)“Revolutionizing the Networking Industry” … prying open the networking devices.

  10. Software Defined Networking (SDN) Decouple the Control and Data Planes

  11. Software Defined Networking (SDN) Decouple the Control and Data Planes Eliminate Control Plan from Network Devices

  12. Software Defined Networking (SDN) Decouple the Control and Data Planes Eliminate Control Plan from Network Devices use separate general purpose machine (“Controller”) to Program and Query the Data Planes of the cheap commodity switches

  13. Software Defined Networking (SDN) Decouple the Control and Data Planes Eliminate Control Plan from Network Devices use separate general purpose machine (“Controller”) to Program and Query the Data Planes of the cheap commodity switches OpenFlow: switch-controller protocol

  14. OpenFlow low-level SDN framework single pattern per rule

  15. NetCorepublished: ACM POPL (Principles of Programming Languages) proceedings 1/2012 high-level Declarative language Expressing packet-forwarding policies on SDNs Expressive: intuitively readable constructs Compositional Formal Semantics

  16. Need for Compiler

  17. $10M series A funding for a SDN “Compiler” 7/2012 http://www.lightreading.com/document.asp?doc_id=227138

  18. NetCore to OpenFlow Compiler a Policy – from NetCore level

  19. NetCore to OpenFlow Compiler a Policy – from NetCore level a Policy – to OpenFlow level

  20. NetCore to OpenFlow Compiler a Policy – from NetCore level a Policy – to OpenFlow level Policy 2 – from NetCore level another Policy – from NetCore level

  21. NetCore to OpenFlow Compiler a Policy – from NetCore level a Policy – to OpenFlow level another Policy – from NetCore level another Policy – to OpenFlow level

  22. NetCore to OpenFlow Compiler combined Policy – from NetCore level combined Policy – to OpenFlow level

  23. NetCore to OpenFlow Compiler Open Source compiler development effort https://github.com/frenetic-lang/netcore coding in Haskell – Functional language Open Source SDN network simulator, and more http://www.sdncentral.com/comprehensive-list-of-open-source-sdn-projects/
