绿色ASON中基于遍历路径的动态多播疏导共享保护研究

Study on Dynamic-Multicast-Grooming Cross-Sharing Protection Based on Spanning Path in Green ASON

研究了基于自动交换光网络(ASON)的多播专用保护。ASON作为具有分布式智能的光传送网,最大特点就是在传送平面和管理平面的基础上引入了具有智能的控制平面,结合ASON优势,设计了辅助图模型,提出了优化模型,并对所设计的算法进行仿真和分析。仿真结果表明,所设计的基于遍历路径的动态多播绿色疏导交叉共享保护具有更低的业务阻塞率,更低的能耗以及较高的工作带宽比。

This paper focuses on the multicast cross-shared protection based on automatic switched optical network( ASON). ASON is an optical transmission network that has distributed intelligence and it introduces the control plane with intelligence based on the transmission plane and the management plane. Thus,with the superiorities of ASON,this paper designs an auxiliary graph and an optimization model,the model includes a virtual topology graph and an integrated graph. The simulation results show proposed cross-sharing protection algorithm has lower blocking probability,higher working bandwidth ratio and more energy saving in the green optical networks.
