Evolution of network-based services that has come to be known as cloud computing gave rise to Software Defined Networking (SDN) and Network Function Virtualization (NFV). These technologies are migrating from data centers to data communications networks, resulting an a paradigm shift in structures and management of networks.
SDN and NFV allow for more flexible and agile deployment of networks and network services, and can facilitate innovation of services. CableLabs is applying Lean Startup methods to develop and validate data models and APIs exposing open source network controller functions for business services applications. The APIs enable use of OpenDaylight open source controller platform to configure virtual switches as virtual business CPEs.
