  The Cloud radio access network (C-RAN) offers a revolutionary approach to
cellular network deployment, management and evolution. Advances in
software-defined radio (SDR) and networking technology, moreover, enable
delivering software-defined everything through the Cloud. Resources will be
pooled and dynamically allocated leveraging abstraction, virtualization, and
consolidation techniques; processes will be automated using common application
programming interfaces; and network functions and services will be
programmatically provided through an orchestrator. OOCRAN, oocran.dynu.com, is
a software framework that is based on the NFV MANO architecture proposed by
ETSI. It provides an orchestration layer for the entire wireless
infrastructure, including hardware, software, spectrum, fronthaul and backhaul.
OOCRAN extends existing NFV management frameworks by incorporating the radio
communications layers and their management dependencies. The wireless
infrastructure provider can then dynamically provision virtualized wireless
networks to wireless service providers. The testbed's physical infrastructure
is built around a computing cluster that executes open-source SDR libraries and
connects to SDR-based remote radio heads. We demonstrate the operation of
OOCRAN and discuss the temporal implications of dynamic LTE small cell network
deployments.
