Openflow Software Defining Networking (SDN) Technology

Asked By Guy R Adams 10 points N/A Posted on - 11/19/2014

I have been reading on this new technology but I do not know much about its inner working. Please briefly bring me to speed with how IP address systems because I am aware that the SDN technology performs similar roles as conversion IP routing and switching systems. Do you know if this new paradigm of SDN is catching on? Could it be the future or it will take a long time for it to exhibit a visible present in IT infrastructure?

Openflow Software Defining Networking (SDN) Technology

OpenFlow is regarded as one of the first standards of SDN or Software-Defined Networking. The communication protocol in software-defined networking is initially defined by OpenFlow that facilitates the OpenFlow/SDN Controller to interact with the forwarding plane and create modifications to the network so it can better adapt to varying business requirements.

In an SDN network, it is the SDN Controller that acts as the brain. It transmits information to routers/switches “below” [through southbound APIs] and the business logic and programs “above” [through northbound APIs]. Any device that needs to work in an OpenFlow environment and wants to communicate to an SDN/OpenFlow Controller is required to support the standard OpenFlow protocol.

With this interface, the alterations to the switch/router flow-table are forced down by the SDN Controller that lets network administrators to partition traffic, begin testing new configurations and applications, and manage flows for optimal performance. See image.
