摘　　要：针对波长交换光网络(Wavelength Switched Optical Network,WSON)规划方案验证和评价的难度,依据WSON规划逻辑和特点,提供了一种准确的方案验证和评价方法。该方法全面考虑了主备路由的路径分离、波长重用和OSNR等因素,并辅以案例分析。Compared to the traditional WDM network, the output amount of WSON network planning is greatly increased, and so is the difficulty of the planning validation and evaluation. Based on the logic and characteristics of WSON network planning, this paper provides an accurate validation and evaluation method, supplemented by case analysis. This method fully considers the path separation, wavelength reuse and OSNR of the work and recovery routes, and is suitable for the planning evaluation or equipment evaluation work.
