3D Fragmentation Metric and RCSA Scheme for Space Division Multiplexing Elastic Optical Networks
TL;DR: A new fragmentation measurement for SDM-EONs is carried out considering the frequency-time-space domain and the routing, core, and spectrum allocation (RCSA) scheme is proposed to allocate the spectrum resource with minimal future fragmentation and core resource with maximal free resource reservation.
