Claim 9:
10. A non-transitory machine-readable medium comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
obtaining first information associated with a plurality of Shared Risk Link Groups (SRLGs);
obtaining second information associated with a plurality of link bundles, each link bundle of the plurality of link bundles being associated with one or more SRLGs of the plurality of SRLGs;
creating a list comprising each Shared Risk Link Group (SRLG) of the plurality of SRLGs, wherein the list identifies a first number of SRLGs, and wherein the list indicates for each SRLG in the list a respective bandwidth loss of each associated link bundle, wherein at least one of the bandwidth losses is less than a complete loss of bandwidth;
creating a plurality of dominance relationships, wherein each dominance relationship comprises for two SRLGs an indication that one of the two SRLGs dominates another of the two SRLGs, and wherein the one of the two SRLGs dominating the another of the two SRLGs comprises: (a) the other of the two SRLGs having each associated failed link bundle also being failed by the one of the two SRLGs; and (b) each associated failed link bundle of the other of the two SRLGs having a respective bandwidth loss that is less than or equal to a respective bandwidth loss of the corresponding failed link bundle of the one of the two SRLGs;
selecting a subset of the set of SRLGs, wherein the subset is selected based at least in part upon the list of SRLGs and the plurality of dominance relationships; and
creating, based at least in part upon the subset, a compressed set of SRLGs that comprises a second number of SRLGs, wherein the second number is less than the first number.
