This paper presents heuristics based on FIPP p-cycle as a solution for the protection problem in elastic optical networks. The proposed algorithms employ failure independent path protecting p-cycle (FIPP). The algorithms differ by the protection of either one or two simultaneous failure as well as by the employment of traffic grooming and spectrum overlap. An integer linear programming (ILP) is formulated and results compared to those given by the heuristics. Results given by the heuristics are close to those given by the ILP.

使用与故障无关的路径保护p周期保护弹性光网络

本文提出了基于FIPP p周期的启发式方法，以解决弹性光网络中的保护问题。所提出的算法采用了与故障无关的路径保护p周期（FIPP）。这些算法的不同之处在于可以同时保护一个或两个故障，也可以通过流量疏导和频谱重叠来实现。制定了整数线性规划（ILP），并将结果与​​启发式方法给出的结果进行比较。启发式方法给出的结果与ILP给出的结果接近。
