Software-Defined Networking Cloud Services & Big Data “In a few years, we can expect the communications industry to look and feel similar to the IT industry.” Network Function Virtualization Operator Paper, Oct. 2012 “SDN is possibly the biggest shift in telecoms in 30 years… The network is finally the computer.” M. Finnie, Interoute, Oct. 2012 Mobile Broadband “Mobile data traffic will increase 13-fold between 2012 and 2017. There will be over 10 Billion mobile- connected devices in 2017.” Cisco Visual Networking Index, Feb. 2013
