VIRTICAL - NETWORK VIRTUALIZATION IN FLEXIBLE OPTICAL NETWORKS
Network Virtualization (NV) has been introduced to overcome the so called network “ossification”, which prevents the seamless provisioning of services on top of dynamic, open and programmable substrate infrastructures. In such context, the providers of optical transport services are expected to greatly benefit from the agility NV promised to introduce in the management of the underlying infrastructure.
Unfortunately, NV on top of optical networks is still not fully deployed, due to various open issues related to the proposed architecture, the mechanisms and the policies. Such issues will be addressed by the VIRTICAL project, which will strongly leverage on the knowledge of the most recent technological solutions (e.g. flexible optical networks) that have been analyzed in the previous research projects, such as AGISCO and FLEXIGO.
