Software Defined Networking: Redefining the Future of Internet in IoT and Cloud Era

Ubiquitous computing with smart mobile devices, Internet of Things, virtualization and cloud is changing yesteryears' static networks to dynamic networks of mobile smart devices and cloud based on-demand services. These changes are growing exponentially and network management is becoming increasingly difficult, be it in smart energy/ transport/cities or in big enterprises. The diverse nature of applications, devices, mobility of the endpoints has challenged IT to look beyond conventional applications for effective security policies, quality of service and performance. This paper describes how the emerging technology- Software Defined Networking (SDN) can be leveraged to provide scalable solutions in this diverse and rapidly changing landscape, reducing both capex and opex. Two use cases, SDN enabled IoT gateways and eNodeB, are covered in this paper. These use cases demonstrate how SDN can be effectively used to address the challenges faced by service providers/IT in managing the dynamic nature of today's networks. These solutions and other such services with help of North Bound APIs can be used in areas like wireless networks, data centers, service providers, enterprise gateways and other such deployments where there is a need to dynamically program networks to make them agile, smarter and faster.
