...In contrast to the routing and spectrum assignment (RSA) problem in EONs with SMF, SDM-EONs with MCF have introduced some new features that make the RSCA problem more challenging....

...To satisfy the strongly increasing future traffic demand, the space-division multiplexing (SDM) technique has recently been proposed, and it is considered to be a promising technology for overcoming the physical limitations of SMF by using multi-core fiber (MCF), multi-element fiber (MEF), multi-/few-mode fiber (MMF/FMF), and their combinations [4]....

...In the traditional WDM systems with SMF, several parallel WDM systems can increase system capacity, but they also increase system cost and energy consumption, leading to the result that the cost and energy consumption remain the same per bit [5]....
[...]
...In contrast to the RSA problem with SMF, which should satisfy the constraints of spectrum continuity, contiguity, and non-overlapping, the XT constraint should be taken into account in the RSCA problem with MCF when assigned the spectral resources, i.e., FSs....
[...]
...However, the growth in the transmission capacity of standard single-mode fiber (SMF) has dramatically slowed because the transmission capacity per fiber is close to the nonlinear Shannon limit of the existing SMF [2,3]....

...The inter-core XT is considered in several works on RSSA, either by using its worst-case estimation [9,10], by applying a best-effort XT avoidance mechanism [11,17,18], or by assuming its strict evaluation [18]....

...Note that we are not considering prioritized area-based methods [18], which are designed to operate on a small variety of request sizes....

...[18], the authors propose a prioritized areas method, which is designed based on statistical characteristics of request sizes in bottleneck links and aims at the reduction of resource fragmentation....
