建立了主干波分复用网络的波长利用率与代数连通性之间的幂函数关系。根据这一观察结果，推导出了一个将波长消耗与网络拓扑结构联系起来的简明预测公式，并对实际的广域网络进行了评估。结果表明，基于代数连通性的波长使用估计比基于节点阶方差、生成树个数和平均节点间距离的估计更精确。
A power law relationship is established between wavelength usage and algebraic connectivity of backbone wavelength division multiplexing networks. From this observation, a concise prediction formula linking wavelength consumption to network topologies is derived and evaluated for real-world wide area networks. It is shown that the algebraic-connectivity-based wavelength usage estimation is more precise than evaluations relying on node degree variance, number of spanning trees, and average internodal distance.
