摘　　要：从系统学和经济学的角度出发,分析了光网络拓扑设计、路由选择、波长分配分别对光网络性能的影响,指出光网络性能不仅取决于路由选择与波长分配算法,并且取决于光网络拓扑设计。进而指出在进行光网络性能优化过程中,以网络拓扑设计作为性能优化的基础,结合路由与波长分配算法、网络服务和市场价格等因素,建立了一种波分复用(wavelengthdivisionmultiplexing,WDM)光网络性能优化的数学模型。最后,给出了WDM光网络性能分析与优化的交互式仿真过程。Based on the systematology and economics, the influence of network design and route selection on wavelength division multiplexing (WDM) optical network is analyzed. The performance of the WDM network not only depends on the algorithm for routing and wavelength assignment but also on the network design. Furthermore, a mathematical model of the performance optimization in WDM network is established, which is based on the network design, algorithm for routing and wavelength assignment, network service and market price. Finally, an interactive simulation process for the WDM network performance optimization is proposed.
