OpenFlow: Software Defined Networking (SDN) Enabler
Shashidhar Gandham

Software Defined Networking aims to bring programmability to network infrastructure and enable rapid adoption of innovations in networking. OpenFlow is a standardization effort to realize SDN. Traditionally, hardware and software in vendor supplied networking equipment is tightly coupled. Command Line Interface (CLI) is the only provided way to control the functionality of switches and routers, thus limiting the capability of others to innovate on networking infrastructure. OpenFlow defines a standard interface for switches and routers that external controllers can use to program the packet forwarding behavior. In this talk we present a real world example to illustrate the need for SDN, OpenFlow packet processing pipeline and details of the OpenFlow protocol.
