Gone are the days where traditional network architectures strictly control public-private demarcations, and depend on site-to-site locations that host diverse, single-function hardware devices.
Today’s workforce is highly mobile and distributed. In many cases, IT has no control over employee locations, the devices they use, and the cloud apps they run. The challenge for IT teams is to get control over this new network paradigm, to provide the reliability, performance and security the enterprise requires, and to ensure a quality user experience.
Today’s modern WANs are based on software defined networking (SDN) principles, and use virtual network functions (VNF) to build diverse connectivity services.
