【摘要】 多粒度交换技术利用波带级路由以及光纤级路由,可有效降低光交叉连接器的复杂度。但多粒度交换 增加了光网络的逻辑层次结构,使得网络中的路由与资源分配问题更为复杂,因此,在多粒度全光网 中实现多层联合路由是提高网络性能的关键。本文对多粒度交叉连接结构进行了分析,并对多粒度全 光网中的多层联合路由问题进行了研究。更多还原

【Abstract】 Multi-granularity switch technologies decrease the complexity of optical cross connects by employing waveband routing and fiber routing techniques. Compared with the traditional wavelength-routed all-optical networks, the routing and resource assignment problem in multi-granularity networks is more complex because of the appearance of waveband tunnel routing and fiber tunnel routing problems. This paper analyzes the architecture of the multi-granularity optical cross connector and proposes the layer graph for routing and resource assignment problem in multi-granularity all-optical networks.更多还原
