In computer networking: “Resiliency is the ability to provide and maintain an acceptable level of service in the face of faults and challenges to normal operation.”〔The (ResiliNets ) Research Initiative definition of resilience.〕 Threats and challenges for services can range from simple misconfiguration over large scale natural disasters to targeted attacks.〔The (ResumeNet Project ) - The need for resilience in current and future networks〕 As such, network resilience touches a very wide range of topics. In order to increase the resilience of a given communication network, the probable challenges and risks have to be identified and appropriate resilience metrics have to be defined for the service to be protected.〔Smith, P. et al., "Network resilience: a systematic approach", IEEE Communications Magazine, vol.49, no.7, pp.88-97, July 2011. DOI: (10.1109/MCOM.2011.5936160 )〕 These services include: * supporting distributed processing * supporting networked storage * maintaining service of communication services such as * * video conferencing * * instant messaging * * online collaboration * access to applications and data as needed Note that resilience and survivability are interchangeably used according to the specific context of a given study.〔Castet J., Saleh J.
