  10. 10. The Concepts Behind SDN are Not Particularly NewThe Separation of the Control Plane has been around for a while…..We saw separatedcontrol & data planes inseparate boxes in theearly ‘90’s…which evolved to a distributedcontrol plane within switches inthe mid -90’s… and then a distributed controlplane in Wireless access points(Aps) by the early ‘00’s…until we saw separatedcontrol and data planes forparticular use cases in thelate ‘00’sCopyright 2013.

  11. 11. There is Past Experience to Draw On• Focused on centralized management & wirelesscontrol-plane• Lack of northbound APIs• Telco Equipment (MPLS, etc.)• Control-plane/Data-plane was separate• Solutions were closed, using proprietarycommunications channelsData Center Chassis-Based Switches& RoutersCopyright 2013. All RightsReserved.11Controller-Based Wireless RoutersThe problem with past solutions is that they only offered narrowapplications of the concepts…and were not truly open for innovation
