Abstract(in English) | Deployment of single layer optical path networks that handle wavelength channels as a single entity is advancing because of continually traffic increase and low power consumption. Hierarchical optical path network that adopts waveband is recognized as a key technology to suppress the optical switch size and to meet the expected traffic expansion in the near future. For both single layer and hierarchical optical path networks, a large part of switches is devoted to realize add/drop operations for originating/terminating paths at nodes. In this paper, we propose new hierarchical optical node architectures that separate add/drop switches from the cross-connect part for routing and reconfiguration of optical paths. The proposed node architecture can not only reduce the total size of the cross-connect part but also minimize the add/drop switch scale for realizing colorless/directionless/contentionless capabilities by introducing a novel switch configuration based on waveband routing. Numerical results show that the proposed hierarchical node architecture can attain 45% switch size reduction at a maximum. |
