XOS brings the Everything-as-a-Service (XaaS) organizing principle to the CORD architecture. In doing so, it addresses several of CORD's high-level design requirements, including a means to seamlessly integrate control plane (SDN) and data plane (NFV) based services; the ability to support both access services and conventional cloud services; support for multiple security domains; and the "end-to-end glue" needed to make CORD both extensible and controllable.

XOS is a self-contained software component – it is a tool used to implement the "CORD Controller" – with other use cases on the horizon.
