Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Several works shed light on the vulnerability of networks against regional failures, which are failures of multiple pieces of equipment in a geographical region as a result of a natural or human-made disaster. This chapter overviews how this information can be added to the existing network protocols through defining shared risk link groups (SRLGs) and probabilistic SRLGs (PSRLGs). The output of this chapter can be the input of later chapters to design and operate the networks to enhance the preparedness against disasters and regional failures in general. In particular, we are focusing on the state-of-the-art algorithmic approaches for generating lists of (P)SRLGs of the communication networks protecting different sets of disasters.
