Multi-granularity optical networks
Résumé
Considering the telecommunication traffic boom, one can wonder if routing nodes will provide the corresponding switching capacity. Introducing Multi-Granularity Optical Networks concept, this paper gives a cost-effective solution. First, a MG-OXC architecture is proposed, then the "natural" distribution of the traffic among the granularities is presented. Finally, a Multi-Granularity planning process is described. Based on the most advantageous feature of optical technologies, the proposed approach solves the switching matrix size limitation.
