Software Defined Networking and Network Function Virtualization – The Foundation of Modern-Day, Intelligent and Open Networks

The telecom industry has always been at the forefront of change as it has dealt with a rapidly shifting business and technology landscape while also managing increasingly high customer expectations. Increased proliferation of smart phones and internet based applications, the 5G explosion, evolving WAN requirements and emergence of new traffic patterns due to IoT and M2M connectivity have been some of the most obvious disruptors. When combined with an intense growth in demand for dynamic bandwidth (driven by video) and new services on the fly, flattening revenues and an intense need to cut costs – service providers have no choice but to transform their networks and operations. OEMs too are facing a big challenge to develop, test and deploy new network elements that offer promising revenue generating opportunities. Finding a way to connect and address all these pain points is important to keep pace with this ever-changing landscape.

SDN and NFV: The whole is greater than the sum of its parts

SDN (Software Defined Networking) and NFV (Network Function Virtualization) have captured people’s attention and are increasingly redefining the way networks are built and managed for a world that is modern, connected and always switched on. The need of the hour is a new software centric architecture based on SDN and NFV combined with server class commodity hardware intended to provide the desired L4 to L7 intelligence in the network which is simplified, agile, programmable, and flexible. Enterprises are also making a similar shift in their data centers, using Software Defined wide area networking also known as SDWAN.
