摘要

本文研究了动态业务条件下基于波带、波长两级交换的多颗粒度光交叉连接节点(MG-OXC)的优化设计

并提出了一种适用于多颗粒度交换光网络(MG-ON)的动态路由、波长分配和业务分组(Traffic Grouping)算法.利用实际网络拓扑对上述MG-ON方案进行了数值仿真实验

比较研究了MG-ON与传统OXC节点构成的波长路由光网络(WRON)的动态业务阻塞率性能

结果表明MG-ON的网络性能可以满足动态业务的要求.

Abstract

This paper focuses on optimized design of Multi-Granularity Optical Cross-Connect(MG-OXC)node base-on two-stage(waveband and wavelength)multiplexing scheme and dynamic algorithm(including routing

wavelength assignment and traffic grouping)for Multi-Granularity Optical Networks(MG-ON)

under dynamic traffic conditions.The performance of our MG-ON

scenario

is evaluated with numerical experiments under NSFNET and ARPANET topology

compared with OXC-based Wavelength Routed Optical Networks(WRON).The results show that the performance of MG-ON can be as good as WRON with proper design.
