ECOC2010: IP Offloading over Multi-granular Photonic SwitchingTechnologies

Telefonica I+D and Intune Networks,


This paper introduces and demonstrates the technical feasibility of a new network architecture where Internet traffic between IP accesses (BRAS) and inter-carrier interconnection nodes is exclusively transported over multi-granular photonic switching technologies without any intermediary transit IP packet processing.

Summary of OPST Performance Benefits

OPST offers significant simplification of network operations as both the optical and OPST layers are hidden freeing operator resources to focus on rapid introduction of client services to generate new revenue streams. The operator has a single infrastructure to manage, but can build virtual bridges on this infrastructure and resell the physical network, as a collection of virtual networks, to other operators and service providers. Within all of these features is the ability to guarantee the bandwidth, latency and jitter characteristics of dimensioned packet flows in services such as ELine, ELAN and ETree as defined by the Metro Ethernet Forum (MEF).

These services can be sold under SLA for a range of classes of service. Finally, the infrastructure can simultaneously offer an adaptive and efficient use of the remaining undimensioned bandwidth for best efforts and internet browsing traffic. This bandwidth can be sold at lower rates but remain profitable as it shares the same infrastructure as other revenue streams.
