— Operators are challenged by the new cloud services, which can modify current traffic pattern. This talk presents the Telefonica I+D view on the evolution towards a transport network ready to support cloud services. It explains the reasons why current transport networks are not efficiently design for a cloud environment and it describes the architecture… (More)
—For many years , the convergence of IP data services and transport network services based on optical transmission has been at the heart of carriers ' investments and business strategies . However , significant challenges still remain. Over time , the inherent technological differences between the IP and transport networks have deeply segmented their… (More)
INTRODUCTION The cloud computing paradigm provides a new model for service delivery where the information technology (IT) resources form a pool able to attend multiple service demands by means of a dynamic assignment of resources, like CPU or storage capacity, either physical or virtual (by using some abstraction mechanisms). Virtualization technology… (More)
This paper outlines some promising results recently obtained in a field trial led by Telefónica and ADVA Optical Networking. The technology tested enables coordinated orchestrations among IP and transport management systems in multi-vendor settings .
