While much has been said about network virtualization, current solutions remain limited to simplistic use cases, restricting services within boundaries of single data centers or virtualized islands. We describe a novel approach that fulfills the promise of massively scalable network virtualization and enables the seamless interconnection of cloud services with existing enterprise environments. Speaker: Scott Sneddon, Principle Solutions Architect, Nuage Networks
