A FierceTelecom eBrief HOW SERVICES VIRTUALIZATION IS EATING THE WORLD June 2017 2 defined wide area networks (SD-WAN), where they want to not only offer remote sites virtual private network (VPN) connectivity, but also additional services such as on-demand virtualized network function (VNF) deployment anywhere, connectivity to public clouds and off-net access as well. ey see these as essential capabilities that will enable them to be more competitive and lower their operational expenses, especially with solutions that can deliver a single end to end solution that is not bound to just the datacenter or the WAN, but both." Kindt adds that the Nokia Telco Cloud Index, a cloud maturity index for operators, shows that many communication service providers are shifting from Proofs of Concept to commercial launches. He says it is now 10 percentage points higher compared to last year's positioning. While Duane DeCapite, senior director of product management at Radisys, comments: "e market is going aggressively in the direction of NFV and SDN. It will allow network providers to roll out services more quickly, in a cost effective manner." IMPLEMENTING SDN AND NFV As top carriers around the world continue to take steps toward an SDN and NFV future, Bruno Jacobfeuerborn, CTO at Deutsche Telekom, comments on where Deutsche Telekom is on this path: "At Deutsche Telekom, we are executing on the strategy we had shared at Mobile World Congress back in 2015. Keep in mind that this is not an easy step – it is a massive transformation for each telco – not only on technology, but also on people and processes. "Back in 2015, Deutsche Telekom launched CloudVPN. Today, this would be called a SD-WAN solution. Many carriers are using these enterprise connectivity solutions as a first step into the new production paradigm [of NFV and SDN]. It is important to gain confidence in the new way of producing services before putting critical services like mobile voice or data on the new platform," Jacobfeuerborn warns. Amy Wheelus, AVP, technology project management, AT&T, says her company is moving quickly towards a virtualized network. She explains: "We will reach a tipping point in 2017 where more than half of our network functionality will be using our SDN architecture. e industry is quickly adopting open network automation platform (ONAP) as the network operating system, with service providers representing over 38% of the world's mobile subscribers signed on to participate in just the first 60 days from launch. As that number climbs, we'll see faster and faster innovation and application of SDN and NFV." She adds that real time communications services and applications were some of the first functions and services to be virtualized, and continues, "But we are now seeing more bandwidth and speed dependent services being virtualized." "The market is going aggressively in the direction of SDN and NFV, which will allow network providers to roll out services more quickly, in a cost effective manner."
