OpenFlow = Control / Data Plane Separation

A

B1

Basic principles:

• Control / Management plane in a dedicated controller

• Networking devices perform forwarding and maintenance functions

• IP / SSL connectivity between controller and OpenFlow switch

• OpenFlow = Forwarding table (TCAM) download protocol
