Abstract
A method for determining a location of a requested resource, comprising receiving a request for a resource, wherein the resource is identified by a hierarchically structured name, decomposing the hierarchically structured name into a plurality of segments, comparing each of the plurality of segments to parent nodes of a plurality of two-level treelets, wherein the comparing of at least two of the plurality of segments to parent nodes of the plurality of two-level treelets is performed in a parallel manner, wherein combinations of two-level treelets comprise a hierarchical name of a network resource, and determining a longest prefix match of the hierarchically structured name.
