SOFTWARE DEFINED NETWORK(SDN)A SHORT GLISMS ABOUT SDN

Software defined Network- The idea of Programmability is the most precise definition for SDN

The technology that is used to separate the control plane of network devices from underlying network plane layer that forwards data. Software-Defined Controller that are lacking concentration from the network Hardware, offering policy based management of the network as a whole.

Resulting SDN cause data center network that is better assigned for the Programmatic network management, application-oriented visibility, and also direct integration with cloud platforms.

SDN promises to reduce the complexity of statically defined networks, making network functions automotive and making it much easier for integration with cloud. SDN has a centralized intelligent entity that has an entire view of the network, that cane make the routing decision based on that view

HOW DOES SDN SUPPORT EDGE COMPUTING, IOT AND REMOTE ACCESS:

Distributing computing power, moving data center functions to the edge router, adopting cloud computing, and supporting Internet of Things(IOT) environments – these can be made easier via SDN environment.

SDN technologies also help in distributed locations that have few IT personnel on site, such as an enterprise branch office or service provider central office, said Michael Bushong, vice president of enterprise and cloud marketing at Juniper Networks.
