This document proposes combining optical network virtualization with network function virtualization to enable on-demand virtual optical networks that are controlled by software-defined networking. Each tenant would have their own SDN controller running in the cloud to control their deployed virtual optical network. The paper demonstrates this use case in a testbed and provides details of a network function virtualization orchestrator that can provide multitenancy over a heterogeneous transport network through network orchestration and virtualization.

1. Multitenant Transport Networks With SDN/NFV
Abstract:
We propose the combination of optical network virtualization and network
function virtualization (NFV) for deployment of on-demand OpenFlow-controlled
virtual optical networks (VON). Each tenant SDN controller is run on the cloud, so
the tenant can control the deployed VON. This paper demonstrates the feasibility
of the proposed use case and provides implementation details in the ADRENALINE
testbed of an NFV orchestrator, which is able to provide multitenancy on top of
an heterogeneous transport network by means of network orchestration and
virtualization.
