Title: Shared Risk Group Vicinities and Methods
Abstract:
A method of managing risk in a network including computing a first path between a source and a destination within the network, computing a second path between the source and the destination within the network, comparing a first risk zone of a first network element in the first path to a second risk zone of a second network element in the second path, the first risk zone is based on a first location-based risk identifier assigned to the first network element prior to computation of the first path, the second risk zone is based on a second location-based risk identifier assigned to the second network element prior to computation of the second path, and an overlap of the first risk zone and the second risk zone indicates that the first network element and the second network element have a shared risk.
