TLDR
In this article, the authors present a strategy for survivability which optimizes primary and backup spectrum allocations and multiple backup route assignments for surviving a connection request, named as Backup Spectrum Reservation with MultiPath Protection (BSR-MPP), which searches multiple backup routes over advance reserved backup resources when an optical connection is concerned.About:

On Energy Efficient Survivable Multipath Based Approaches in Space Division Multiplexing Elastic Optical Network: Crosstalk-Aware and Fragmentation-Aware
TL;DR: Two energy-efficient heuristics are proposed 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.

Minimization of the network availability upgrade cost with geodiverse routing for disaster resilience
TL;DR: This paper considers a given core optical network such that the current availability and the cost of upgrading it to a higher value are known for each network link (or edge) and proposes a new ILP based heuristic.

Quasi Path Restoration: A post-failure recovery scheme over pre-allocated backup resource for elastic optical networks
TL;DR: Quasi Path Restoration provides a reasonable trade-off between bandwidth blocking probability and connection recoverability and is compared with Shared Path Protection and Primary First-Fit Backup Last Fit strategies in terms of Bandwidth Blocking Probability (BBP) and average frequency slots per connection request.

Survivability using traffic balancing and backup resource reservation in multi-domain optical networks
TL;DR: To provide an acceptable level of service even when a connection fails, traffic balancing (TB) based solutions where the intra/inter‐domain traffic is slided as well as shifted (S3‐TB) performs best, and for further improvement in S3‐ TB, backup multiplexing with advance backup resource reservation (BRR) is incorporated and evaluated.
