SDN's Evolution Continues

Below are trends and predictions that enterprise organizations will experience in 2017. The subjects range from the evolution of SDN, to open source approaches and what is happening to traditional switching and routing.  

Traditional switching and routing is fading - For years, the demise of switching and routing has been announced in trends and predictions over and over again. Though the functionality of both will not go away, the traditional switching and routing approach will change as better virtualized solutions and software defined methods improve deployments and access. To meet the evolution of switching and routing, true network hardware virtualization is required to create virtual forwarding context (VFCs) at WAN scale.

Prediction: We expect to see more service providers' leverage networking equipment that delivers WAN-scale open, programmable SDN capabilities to deliver innovative services and service level assurance and programmable networking so operator's and their customers can spin up new services quickly and easily.

SDN virtualization to accelerate on demand service - Last year we witnessed the deployment of SDN in service providers, internet exchanges, ISPs, and data centers. What's consistent across all of them is they avoided delays caused by the often difficult integration of SDN orchestration, control and data plane elements. By moving past this integration roadblock, service providers have accelerated the ability to ramp up on-demand services that provide greater control and orchestration.

Prediction: As on-demand services become the standard, more service providers will leverage open SDN solutions to help deliver the services needed.

Security in an SDN world - Building open programmable networks can create security risks, adding to the rapidly increasing rate of attacks on networks.  But with the right approach and tools SDN done right can translate into two important developments:  value-added security by-design in the SDN implementation itself and by offering added policy-based secure traffic passage.  Around this latter point, the level of automation and programmability SDN delivers can play a big role in securing the network. Many human made mistakes can be significantly reduced with agile, simplified, and open software defined networks that can dynamically adjust to different security needs and threats.

Prediction: More companies will look to SDN, NFV solutions that provide automated, policy-aware security in the control/data plane and alleviate the perceived security holes due to open virtualized networks.

Open Source the right approach to SDN - As service providers and ISPs increasingly look for greater efficiencies in delivering new services to customers, they will turn to the solutions that provide closer to 80 percent of the capabilities needed to control the data plane via open source or vendor supplied code, thereby avoiding hiring a large team of programmers to build a learning bridge or router from scratch. Operators will only have to do 20 percent of the work to customize their networking solution with value-add features that make it their own.  This is the path that will lead to wide deployment of SDN by service providers.

Prediction: Expect to see service providers and ISPs opt for SDN solutions that are more turn-key in providing control across the network and leave 20 percent for the provider's creative input.
