Webb4 maj 2024 · Abstract: Shared Risk Link Group (SRLG) is a failure the network is prepared for, which contains a set of links subject to a common risk of single failure. During planning a backbone network, the list of SRLGs must be defined very carefully, because leaving out one likely failure event will significantly degrade the observed reliability of the network. 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. WebbAn operator may also need to avoid a path that uses specified nodes for administrative reasons. If a specific connectivity service is required to have a 1+1 protection capability, two separate disjoint paths must be established. A mechanism known as Shared Risk Link Group (SRLG) information may be used to ensure path diversity.¶ greco roman domesticated animals

WebbIntroduction It is important to understand which Traffic Engineering (TE) links in a given network might be at risk from the same failures. In this sense, a set of links can constitute a Shared Risk Link Group (SRLG) if they share a resource whose failure can affect all links in the set [ RFC4202 ].
