“…They later proposed a shared path based survivability scheme in 2017 [6], which produces better results compared to their previous work [29]. In [5], H. M. N. S. Oliveira and N. L. S. da Fonseca proposed three different RSCA algorithms, namely SBPPMC (shared path based), FIPPMC (p-cycle based) and MIFMC (p-cycle based) for protecting routes in SDM-EON in case of single link failure. Inter-core cross talk is measured, and a connection is established based on the value of threshold crosstalk (-16dB).…”

“…Due to the additional spatial domain, there develops another constraint: core assignment in SDM-EONs [4]. The interference in between adjacent cores due to propagation of signals with the same frequency in MCF based EONs is called intercore crosstalk [5]. Reducing crosstalk among adjacent cores is a primary concern nowadays.…”

“…In shared path protection, the backup path is designed for each request in a manner such that more than one backup path of different requests can share resources if their working paths are link disjoint. P-cycles are pre-configured cycles which can preconfigured backup resources by providing protection to oncycle spans [5]. Multipath based survivability allows traffic routed through a link-disjoint set of paths connecting sourcedestination (s-d) node pair to ensure the propagation of a significant amount of traffic data through other paths despite the presence of a single link failure in any of these selected paths.…”

“…The second one primarily tries to reduce spectral fragmentation as much as possible, while maintaining inter-core crosstalk below some threshold level. Both of them are compared with the algorithms proposed in [5] with respect to BBR, network energy consumption, fragmentation ratio, and crosstalk per slot ratio.…”

In this paper, we have proposed two energy-efficient heuristics: (i) CMDE-RSCA (crosstalk-aware), and (ii) FMDE-RSCA (fragmentation-aware) to address the issues of inter-core crosstalk, and fragmentation within the core respectively-to ensure quality transmission of the optical signal for dynamic traffic in space division multiplexing elastic optical network (SDM-EON), while maintaining survivability of the network against single link failure. These heuristics based on multipath based survivability are compared with three existing survivable approaches based on p-cycles and shared path in terms of bandwidth blocking, energy consumption, crosstalk, and fragmentation. Both these algorithms outperform all three existing heuristics in terms of all parameters. In between CMDE-RSCA and FMDE-RSCA, CMDE-RSCA leads to consume lesser energy, whereas FMDE-RSCA produces lesser bandwidth blocking.
