AT&T Optimistic about SDN- and NFV-Based Network Solutions



AT&T’s SDN benefits

AT&T (T) is focusing on SDN (software-defined networking) and NFV (network function virtualization) technologies to transform its network. The company is looking forward to achieving rapid service delivery along with efficient utilization of its capital. It believes that the combination of its SDN- and NFV-based network solutions could reduce network delivery costs as well as SG&A (selling, general, and administrative) expenses. This methodology requires mobile operators to virtualize their networks rather than spend money on dedicated fixed hardware.

At the end of 2017, ~55% of AT&T’s network functions were virtualized. It’s on track to meet or exceed its target to virtualize 75% of its network functions by the end of 2020.
