Review: Software Defined Networking and OpenFlow
Keywords:
Software defined networking, OpenFlow, VirtualizationAbstract
This review paper explains Software Defined Networking (SDN), wherein control and forwarding planes are detached, shifting all the network intelligence to a server (SDN controller) to make a logically centralized network infrastructure. Open Flow protocol is the communication interface between control and forwarding plane. It allows researchers to experiment their abstractions in heterogeneous environment in a uniform way at line-rate and with high port-density; while on the other hand, manufacturers need not reveal the interior design and operations of their switches. Open Networking Foundation (ONF) community is encouraging different vendors to introduce OpenFlow in their products and elevate networking related innovations in world-wide college campuses.
