【摘要】 本文研究了在波长路由的智能光网络中选择路由与波长分配 (RWA)过程中如何考虑非线性效应的影响 在简要分析了考虑非线性效应影响的必要性后 ,以交叉相位调制为例推导出了一种简单的计算非线性效应引起的光功率代价计算公式 ,并讨论了如何将其引入路由与波长分配算法中 仿真结果表明非线性效应确实对RWA的优化结果产生一定的影响 ,其程度与物理拓扑、业务需求和具体的网络传输参量有关更多还原

【Abstract】 Issue for routing and wavelength assignment (RWA) with nonlinearities considerations in intelligent optical networks is discussed. An algorithm for calculation of the cross-phase modulation-induced penalty is developed and method of introducing it into RWA problem is presented. Numerical results show its impact on the network performance depends on the network topologies, traffic demands and physical parameters.更多还原
