We present a new path protection algorithm, called resource sharing degree constraints (RSDCs), for survivable wavelength-divisionmultiplexing mesh networks. We define a parameter k to adjust the resource sharing degree (RSD). When we compute the reserved backup wavelengths, if the RSD is larger than the value of k, more wavelengths are assigned until the RSD is not greater than the value of k. With respect to previous work, RSDCs, adds a valuable elasticity in resource assignment and is able to determine the appropriate trade-offs between the resource utilization ratio and the protection ability.
我们提出了一种用于可生存波分复用网状网络的新路径保护算法，称为资源共享度约束（RSDC）。我们定义了一个参数k来调整资源共享度（RSD）。在计算预留备份波长时，如果RSD大于k的值，则分配更多波长，直到RSD不大于k的值。相对于以前的工作，RSDC在资源分配中增加了宝贵的弹性，并且能够在资源利用率和保护能力之间确定适当的权衡。
