Overview
ONOS allows one to define virtual networks in terms of virtual devices and links.

Consequently, virtual links can be defined as pairs of virtual devices ports, where the underlying devices are not necessarily adjoining. Assuring connectivity between the ports of a virtual devices and the connectivity over virtualized links, will be the job of a VirtualNetworkProvider, which can chose whatever tunneling mechanism it deems appropriate.
