Today SDN has broader global initiatives and policies nabbing the growth of new form of sophisticated, cost-effective, scalable and futuristic network systems. This holistic move is gradually deriving SDN as a juggernaut. Though awareness and meagre eruditeness has somewhat kept it afloat in the Indian market, companies like Juniper Networks is rolling the show. Getting hold off the show-runner of this emerging sector – Sajan Paul – Director Systems Engineering, India & SAARC at Juniper Networks orate the landscapes SDN is creating for digital-ready networks.
- How will SDN change the operations and implementations of new software-based operations for telecommunications?
Amidst all of the innovation taking place as part of the 5G transition, the distributed cloud framework is at the center of focus. Faster deployment, ease of operations and bringing content closer to the customer are all extremely important for 5G to be successful. Another key use case of SDN is in building automation for ease of deployment and operations. It also paves way for newer service introduction like – NFV, SD WAN etc.
2. There are challenges while adopting SDN solutions, standing in 2018 how the solution-enablers are overcoming the glitches. P.s.(Security, scalability, Interoperability, reliability etc)
One of the key challenges is the co-existence of legacy and the newer generation systems. There are also challenges around the mindset. We need to transform the operations domain into more of a devops / Netops domain. There is a dire need for continuous development, testing and rollout.
3. To Indian perspective, how you see the market maturing and its adoption rate. What are key business models suiting the Indian ecosystem?
SDN, in the telecom world, is largely focused on automation solutions. There are tested and proven methodologies in this space. Real telco cloud and NFV framework will be amplified when we transition into 5G solutions in the near future. In fact, SDN will be the cornerstone for a successful 5G rollout.
4. What are the latest trends in SDN which will furnish the market in 2018 and beyond?
The market is converging into open standards and expanded eco-system. Openstack is leading the pack for Telco cloud and NFV deployments. Juniper Contrail networking is one of the leading SDN providers supporting a series of hypervisors, agnostic to network gears, bare metal and legacy support to name a few, while the Contrail multicloud security provides unified boundary-less policy control.
5. 4.5G and 5G are at the shore, though India still struggles with 4G connectivity and speed. How SDN adoption by telecommunication players will change the scenario.
There is no shortcut for radio spectrum and last mile connectivity. These are the key challenges that plague Indian Telcos. Rapid execution of NOFN and fiberization projects will help accelerate the 5G revolution. SDN will be the cornerstone in enabling micro services at cloud scale. This will accelerate key services like IoT broadband at large.
