Toward cloud-ready transport networks

This article presents an operator's view of the evolution towards a transport network ready to support cloud services, which are hosted in data centers and reachable through the network. This work shows the reasons why current transport networks are not efficiently designed for a cloud environment, and it describes the architecture for a cloud-ready network. To show the feasibility of such a cloud-ready network, we present three experimental validations of the concepts to support our network evolution.
