In this Letter, we propose two crosstalk-aware routing, core, and spectrum assignment (CA-RCSA) algorithms for spatial division multiplexing enabled elastic optical networks (SDM-EONs) with multi-core fibers. First, the RCSA problem is modeled, and then a metric, i.e., CA spectrum compactness (CASC), is designed to measure the spectrum status in SDM-EONs. Based on CASC, we propose two CA-RCSA algorithms, the first-fit (FF) CASC algorithm and the random-fit (RF) CASC algorithm. Simulation results show that our proposed algorithms can achieve better performance than the baseline algorithm in terms of blocking probability and spectrum utilization, with FF-CASC providing the best performance.

智能光网络技术和P2MP(点对多点)技术的融合将能够极大地促进光组播业务的发展。文章针对多层多域光网络中的P2MP业务, 提出了一种MDMPH(基于分层PCE(路径计算元素)的多域最小代价路径启发式)算法, 并进行了仿真分析。与传统的PDB(基于逐域路径)算法、E-BRPC(基于扩展的反向回溯)算法以及CTB(基于核心树)算法相比, MDMPH算法能够计算出代价更小的P2MP路径树。
