AT&T's Donovan: Wireless network costs decreasing due to SDN, Ethernet backhaul, cloud computing
August 12, 2015
John Donovan, senior EVP of AT&T's (NYSE: T) technology and operations, said the carrier is rapidly moving to deploy software-defined networking (SDN) into its mobile network to lower the company's networking costs.
"We're collapsing the core of the network," Donovan said during AT&T's analyst day. "The first software-defined networking thing we did was that mobile packet core. And we're starting to move large amounts of traffic in our mobile network onto a software-defined architecture."
Donovan explained that today's wireless networking requirements are challenging, considering wireless networks today are being called on to deliver both data-heavy video as well as lightweight Internet of Things (IoT) communications.
