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.
In a flurry of activity throughout the week, Donald (DJ) LaVoy, Deputy Under Secretary for Rural Development at the US Department of Agriculture, and his team spent about $145.8 million in the non-urban or suburban areas of seven states.
Calix reported revenue of $120.19 million – up 4% – in Q4 2019, putting a bounce in the step of company president and CEO Carl Russo and a shine to Calix's ongoing transition from hardware vendor to a provider of platforms enabled by cloud, APIs and subscriber experience.
Looking to curtail e-waste and improve the bottom line, BT will require customers to return routers and set-top boxes, although subscribers will not have to pay a fee when they receive regular broadband equipment.
Deploying DOCSIS 3.1 across its entire footprint gave Rogers Communications the ability to offer speeds of up to 1 Gbit/s,
contributing to a broadband segement that generated about 60% of the Canadian operator's $3.05 billion (US) in Q4 cable earnings.
Over the next two years, approximately 60% of service providers (both large and small) will adopt virtualization on a wide scale across their networks, according to the latest survey report from Ovum. Why are providers making these moves? Is there an easy way to start?
Learn how and why service providers are using virtualization to transform their networks. This webinar will look at how providers are leveraging virtualization to create more flexible and agile networks while also providing a better customer experience. Expert speakers from netElastic and Heavy Reading will address the industry drivers for network virtualization, the benefits that can be realized, the challenges to face and the results of virtualization being achieved by providers today.
Key topics will include:
Current network infrastructure and the move to virtualization
Benefits and challenges of network virtualization
How providers can get started
Service provider success stories: the decision to virtualize, the solution, and results
