“…Some subnets became unreachable before the hurricane reached any subnet region. Power outage and lack of spare power were found as being the most important causes to justify the low correlation obtained [4]. Similar other investigations exist for other weather-based disasters as in [6], [7].…”

Abstract-Due to the increasing dependence on network services of our society, research has recently been concentrating on enhancing traditional protection strategies to withstand largescale failures, as in case of disaster events. The recently-formed EU-funded RECODIS project aims at coordinating and fostering research collaboration in Europe on disaster resiliency in communication networks. In particular, the Working Group (WG) 2 of the RECODIS project focuses on developing new networkresiliency strategies to survive weather-based disruptions. As a first step, WG2 members have conducted a comprehensive literature survey on existing studies on this topic. This paper classifies and summarizes the most relevant studies collected by WG2 members in this first phase of the project. While the majority of studies regarding weather-based disruptions deals with wireless network (as wireless channel is directly affected by weather conditions), in this survey we cover also disasterresiliency approaches designed for wired network if they leverage network reconfiguration based on disaster "alerts", considering that many weather-based disruptions grant an "alert" thanks to weather forecast.

“…Cyber hazards can include the illegal disclosure of stolen data, data that have been altered by illegal means or malware, unexpected loss of data, and contamination of data. Other related issues include non-performance of components, wireless communication connectivity issues, malware, attacks, misconfiguration due to human error, power failure, natural hazards and disasters (Erjongmanee and Ji, 2011;Djatmiko et al, 2013;Arif and Wang, 2018). The TWG recognised the critical importance of cyber and other technological hazards and agreed to include them in the Sendai Framework review of definitions.…”

Disaster-Resilient Optical Network Survivability: A Comprehensive Survey

Network survivability endeavors to ensure the uninterrupted provisioning of services by the network operators in case of a disaster event. Studies and news reports show that network failures caused by physical attacks and natural disasters have significant impacts on the optical networks. Such network failures may lead to a section of a network to cease to function, resulting in non-availability of services and may increase the congestion within the rest of the network. Therefore, fault tolerant and disaster-resilient optical networks have grasped the attention of the research community and have been a critical concern in network studies during the last decade. Several studies on protection and restoration techniques have been conducted to address the network component failures. This study reviews related previous research studies to critically discuss the issues regarding protection, restoration, cascading failures, disaster-based failures, and congestion-aware routing. We have also focused on the problem of simultaneous cascading failures (which may disturb the data traffic within a layer or disrupt the services at upper layers) along with their mitigating techniques, and disaster-aware network survivability. Since traffic floods and network congestion are pertinent problems, they have therefore been discussed in a separate section. In the end, we have highlighted some open issues in the disaster-resilient network survivability for research challenges and discussed them along with their possible solutions.
