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.

"As you scale up your operations, you gain more benefit," he said. "Directionally, that's where everyone knows they're going. 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.
After suffering many quarters of financial and broadband subscriber losses, Frontier Communications' bond owners are ready for dramatic change – including a replacement for CEO Dan McCarthy (pictured), Bloomberg reports today, citing several sources.
Verizon and Calix bonded four wavelengths in the lab, bringing Verizon closer to its goal of one unified network for multiple services, says Kevin Smith, vice president of network planning at Verizon, during Calix ConneXions 2019 in Las Vegas.
Calix must overcome ties to its hardware-based past and return to positive earnings, something CEO Carl Russo predicts will happen soon -- pointing to the vendor's flat Q3 earnings and uptick in Verizon orders as positive financial indicators.
The ongoing debate around GPON vs EPON can get as heated as discussions around politics and religion, but both technologies offer some advantages over the other depending on the needs your network is servicing.
In this webinar, we will focus on the facts around the GPON vs EPON debate and how that technological decision is almost always made based on factors outside the technology itself.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
