Based on MG-OXC routing and multi-Granularity assignment algorithm

In this paper we focuses on the optimal design of Multi-Granularity optical Cross-connect (MG-OXC) node based on three stage (fiber, waveband, and wavelength) multiplexing scheme and dynamic algorithm (including routing and multi-Granularity assignment algorithm) for Multi-Granularity Optical Networks (MG-ON), under dynamic traffic conditions. The proposed MG-OXC routing and assignment algorithm can reduce both the number of used ports and the cost of an existing network. The performance of our MG-ON scenario is evaluated with numerical experiments under NSFNET topology and comparisons are made with OXC-based wavelength routed optical networks. The results show that the performance of MG-ON is close to WRON with proper design.
