AT&T's Kris Rinne explains how 'User-Defined Network Cloud' will change carrier's network architecture
BARCELONA, Spain - March 03 2014
AT&T Mobility (NYSE:T) during last week's Mobile World Congress announced plans to implement a network architecture it described as a "User-Defined Network Cloud," which the carrier said would be supported by its previously announced Domain 2.0 supplier program. AT&T said the network cloud effort would allow it to use Network Function Virtualization (NFV) and Software Defined Networks (SDN) technologies to separate its hardware and software functionality; separate its network control plane and forwarding planes; and improve its management of functionality in the software layer. AT&T named Ericsson, Tail-F Systems AB, Metaswitch Networks LTD and Affirmed Networks Inc. as the initial vendors working on the program. AT&T said it wouldn't adjust its capital expenditures guidance due to the program, but that over time it expects the overall Domain 2.0 program to "reflect a downward bias toward capital spending."
