WebbMPLS Traffic Engineering: Shared Risk Link Groups Information About MPLS Traffic Engineering: Shared Risk Link Groups 3 MPLS Traffic Engineering Shared Risk Link Groups SRLGs refer to situations where links in a network share a common fiber (or a common physical attribute). If one link fails, other links in the group may fail too. 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.
