| Outline of Final Research Achievements |
Architectures and design methods for coarse granular optical path routing networks were studied throughout the period. One of proposed design method optimizes multiple coarse granular optical pipes according to the optical path distribution in a network and numerical experiments on real network topologies elucidated the validity of the method. Network expansion throughout the lifetime of a coarse granular optical path routing network was also studied. Moreover, the introduction of machine learning techniques to optical path networks was studied where the penalty caused by misjudgements is crucial as the infrastructure of ICT society.Proposals in this area include a power consumption reduction for electrical large scale routers, a signal boundary optimization for optical receivers, and a dynamic optical path control method according to traffic variation.
