Large capacity optical networks applying multi-stage hetero-granular optical path routing
We propose a novel scalable large-scale OXC architecture with a two-stage hetero-granular optical path switching mechanism based on a combination of different granular optical selective switches and an appropriate network design algorithm that can make the best use of the proposed OXC architecture for building cost-effective large capacity optical networks. Simulation results verify that our proposed solution can offer a significant overall network cost reduction. The cost efficiency of networks based on the architecture is also investigated in relation to switching component cost and different network parameters.
