"WebbAt backbone network planning, an important task is to identify the failures to get prepared for. Technically, a list of link sets, called Shared Risk Link Groups (SRLG), is defined. The observed reliability of network services strongly depends on how carefully this list was selected and whether it contains every high-risk failure event. Regional failures often … " - Shared risk link group
