摘要
文章通过实际网络模型对运用自动交换光网络(ASON)设备组建网状网(mesh)的经济性问题进行了深入研究。根据中国移动骨干传送网现状和预测的2007年业务网需求增长情况,使用网状网容量优化规划工具,仿真分析了使用环网扩容或以不同节点数量引入ASON网状网方案之间的经济性对比,从网络拓扑的角度研究了中国移动骨干传送网向ASON网状网演进的经济性优势。
In this paper, we focus on the study of the cost in AS ON mesh networks, introduce a capacity efficient model to describe and compare the economics of the ring and mesh networks. The simulation network architecture is the China Mobile＇s core optical transport networks,the traffic model is the requirement of China Mobile services development in 2007. By using simulation tool, we analyzed the capacity efficient of ring network and mesh network, which have diversity node numbers, and the result shows that it is feasible and necessary to introduce ASON mesh networking in China Mobile core optical transport networks.
