The increasing diversity and complexity of traffic traversing the Internet of Everything- today can be imagined as a three-dimensional collection of intersecting highways of different kinds (e.g., corporate WAN, Internet, mobile, Wi-Fi, cellular, cable, cloud), with a wide array of vehicles (e.g., PCs, tablets, smartphones) carrying various types of passengers (e.g., data, voice, video, email, SMS, Web). Emerging traffic from the new category of machine-to-machine communications is scaling exponentially and introducing new policy triggers.
In this new environment network operators must become master traffic controllers to deal with all of the volume, diversity, and complexity. The most innovative and forward-looking experts are aggressively looking into providing more open programmatic access to their network functions and services. The goal is easier and faster control, in order to make them more agile, flexible and application interactive while at the same time optimally aligning costs with potential new revenues.
