"Programmable networks provide one approach to meeting some of these challenges. Virtualization of network functions is an other approach providers are pursuing to improve flexibility and service agility and significantly transform their economic cost models. Operations- and services-automation software capabilities are also required to dynamically accelerate and monetize the creation of new services. Solutions must address many different use cases and opportunities, necessitating a comprehensive and holistic approach that orchestrates programmable networking technologies along with multiple other powerful solutions. That is the vision of the Cisco Open Network Environment (sometimes referred to as Cisco ONE).
