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 for… (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 operation,… (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 .
