Following is information and insight from IHS Markit about our 2016 Carrier SDN Strategies Global Service Provider Survey

Bottom Line

  • Three-quarters of carriers participating in the IHS Markit software-defined networking (SDN) survey say they have already deployed or will deploy SDN in 2016; 100 percent plan to deploy the technology at some point
  • The top drivers for service provider SDN investments and deployments are simplification and automation of network and service provisioning, as well as service automation
  • Most operators are moving from SDN proof-of-concept (PoC) evaluations to commercial deployments in 2016 and 2017

Our Analysis

In our fourth annual survey of carrier SDN strategies, it’s clear that service providers around the globe are investing in SDN as part of a larger move to automate their networks and transform not only their networks, but also internal processes, operations and service offerings.

Service providers believe that SDN will fundamentally change telecom network architecture and deliver benefits in service agility, time to revenue, operational efficiency and capex savings.

And these operators want SDN in most parts of their networks. Survey respondents’ top three SDN-targeted network domains for deployment by the end of 2017 are within data centers, between data centers and access for businesses.

Still, carriers are starting carefully with SDN, biting off small chunks of their networks called “contained domains” in which they will explore, trial, test and make initial deployments. Momentum is strong, but it will be many years before bigger parts of networks or entire networks are controlled by SDN—although a few operators are leading the way including AT&T, Level 3, Colt, Orange Business Systems, SK Telecom and Telefónica, among others.

The industry is still in the early stages of a long-term transition to SDN and network functions virtualization (NFV) architected networks. Much continues to be learned as each year passes, and various barriers and drivers have become more prominent as operators inch closer to commercial deployment. In this year’s survey, for example, respondent operators indicated that their top barriers to deployment are the lack of carrier-grade products and integration of virtual networking into their existing physical networks. Nonetheless, they rated virtual customer premises equipment (vCPE) managed services as the top SDN/NFV application for producing new sources of revenue.

Carriers are learning that some avenues are not as fruitful as expected, and telecom equipment manufacturers and software suppliers may well invent new approaches that open up new applications. IHS Markit will conduct the fifth annual SDN survey in 2017, and it will be interesting to see what new issues emerge and which problems get resolved in the additional commercial deployments planned for 2016.

SDN Survey Synopsis

The 22-page IHS Markit SDN strategies survey is based on interviews with purchase-decision makers at 28 service providers around the world that control 53 percent of world’s telecom capex and are deploying or plan to deploy SDN in their networks in the future. Operators were asked about their strategies and timing for SDN, including deployment drivers and barriers, target use cases, applications and more.
