SD-Access: The Foundation for Transformation While most, if not all, large telco and cable operators agree their network destinations must include SD-Access, the route is paved with multiple options, ADTRAN's Robert Conger said in a recent UBB2020 Radio show. And judging by the number of panels and discussions at MEF 2017 in Orlando this week, service providers also have many questions, even as they field-trial solutions this year, with plans to begin market deployments in 2018. "Software-defined access refers to that underlying broadband access that builds connections out to the end user," Conger said. These networks now are more software-defined and programmable, include virtualization and disaggregation to separate hardware and software, and feature lightweight modular components based on data center design, he said. And the more SD-Access operators deploy, the greater the return, he added.

It's a matter of implementations and timelines -- how you get there -- which is very different from where we were a few years ago." That time marked the beginning of CORD -- central office rearchitected as a data center -- and there was some "healthy skepticism" from operators that did not initially see the benefit for access networks and broadband access, Conger said. Once service providers began reaping CORD's benefits, the idea of applying the same general principles -- virtualization, disaggregation and native SDN controls -- to the access network gained traction. They're also gaining urgency as service providers seek new ways to compete through rapid service deployment and customization, 5G preparedness and operational efficiencies, he added.
