Download forwarding state (FIB) from the controller using special protocol Must provide all the functions of an existing set of networking protocols And do them at sub-second failover 6 Out of Band Control Plane Controller Download FIB Openflow’s objective is to separate the control plane from the dataplane

Centralized Management ATM SONET PBT 8 OpenFlow SDN Many historical examples Old idea, reintroduced as something “new”. Powerful, but dangerous E.g. sweetest of honey pots, target for hacking

Programmability could be used to improve network management, but it really doesn’t have any impact on the first two options: simplification of architecture and reduction of hardware costs. - Zeus Kerravala
