【摘要】 由于外力施工和自然灾害等原因,往往会造成同一物理路由的多根光纤同时断裂,因此在多纤光网络中,确定工作通道和保护通道,仅与链路无关还不够,必须要求物理路由不相关.基于这一观点,从提高网络生存性的角度出发,提出了一个适合于多纤光网络的路由波长分配算法———光纤物理路由最大不相关算法.文中介绍了算法的基本思想、实现方法、仿真模型及结果示例.更多还原

【Abstract】 In a multiple fibers optical network, multiple fibers in the same physical route may fail at the same time besause of mechanical coustruction and destructive natural events,so to determine the primary path and to protect the path, link disjoint is not enough,and the optical fiber physical route disjoint is essential. Base on this idea, in order to improve the survivability of a multiple fibers optical network, a new routing assignment algorithms-diverse fiber physical routing algorithms is presented. The idea, realization method, simulation mo-(del ) and simulation results are introduced.更多还原
