Creating Future Energy Efficient Network Services through Optical Technologies

Two newly-structured optical network architecture alternatives are proposed for creating new network services. The first target is an energy efficiency network, a data center-centric optical aggregation network based on wavelength/time-slot multiplexing. Not only application layer functions but also all layer-3 or upper traffic are transferred through the optical aggregation network and switched in the huge centralized router at the data center. Power consumption of the network can be reduced ten or twenty fold compared to the existing Internet. The second is a service mash-up network that uses broadband optical wire under the IoT generations. All service contents, hardware, and software programs are defined as a service part. Optical wire interconnects some service parts and creates new mash-up services in the network. That creates deep network functionality in combination with network and processing functions.
