SDN in the WAN: the open programmable user plane could kickstart a new era

Caroline Chappell Research Director

"Operators and established network equipment vendors risk losing further influence over the future of the network if they ignore the possibilities and challenges of an open, programmable user plane."

Web-scale companies are setting the software-defined networking (SDN) agenda and their latest support for an open programmable user plane will create a new SDN battleground in 2018. The programmable user plane is likely to become a key constituent of an end-to-end 5G architecture spanning the data centre and WAN.
