2. Introduction
Introduction
Community networks leverage networking resources from the
community itself to offer telecommunication networks for the same
community.
Scalability.
Privacy.
Control.
Software-Defined Networking (SDN) offers a global view of the
elements composing the network.

4. Introduction
CHIEF
A networking platform for clouds of Software-Defined Community
Networks.
Offers a controller farm through a federation of SDN controllers
to orchestrate the multi-tenanted community network.
Interoperable clouds of community networks
by extending and deploying a federated and orchestrated cluster of
SDN controllers.
Complimentary business functionalities for inter-community network
clouds.
Monitoring.
Throttling.
Metering.
