基于MLAG的三层码分多粒度光交换系统的性能研究
MLAG-based research on the performance of a three layer multi-granularity optical cross connection system
摘要
Abstract
In this work, optical code switching is introduced based on wavelength switching, then a three-layer multi-granularity optical cross connection (MG-OXC) system is constructed on the basis of optical code division multiple-xing ( OCDM), and a new traffic grooming algorithm is presented.The proposed architecture can improve the flexi-bility of traffic grooming, reduce the number of wavelengths used and save the number of consuming ports, hence, it can simplify routing device, effectively improve the flexibility of traffic grooming between nodes and enhance the performance of the system.The structure of the three-layer MG-OXC system is briefly interpreted and the compari-son of saving ports is given.The good performance of the system is showed through the analysis of the exchange structure network model and the establishment of traffic grooming link on the multicast layered auxiliary graph ( MLAG), and the simulating of the blocking rate and the throughput.关键词
