Editor's Corner—Telecom’s move to software and virtualization hounded by the same old problems | FierceWireless May 2017
"For years, carriers and vendors have been touting the wonders of software-defined networking (SDN) and network functions virtualization (NFV). These technologies, the argument goes, will enable network operators to replace expensive, proprietary hardware with software-powered, virtualized services running on cheap, off-the-shelf hardware. The result, vendors and carriers have said, will be an industry that can pivot on a dime, quickly developing and launching new, powerful, revenue-generating services while cutting costs in the process. The result, however, is not quite that. At least not yet."

Level 3 "is reluctant to go much further down that path due to concerns that what the company develops might not interoperate with services from other vendors or carriers"

"AT&T, an early mover in the SDN and NVF space, has said it expects that fully 55% of its network operations will be virtualized by the end of this year. . . . But still, AT&T doesn’t yet have any concrete cost savings it can point to from its virtualized, software-powered migration."

Verizon "said that the operator’s decision to standardize much of its software efforts on OpenStack “is a challenge right now.” "

"But standardization efforts in this area are still in their early phases, and expenses are mounting."

"It’s no surprise that the telecom industry is calling for more interoperability in its migration to SDN and NFV. After all, interoperability is one of the few key tenets underpinning the growth of the global telecommunications industry—communications only work when everyone speaks the same language."
