Abstract

A method for inserting a first prefix, including segmenting the first prefix into a first plurality of segments, indexing into a first trie node block using a first segment of the first plurality of segments to obtain a first trie node, obtaining a second segment of the first plurality of segments, determining whether the second segment of the first plurality of segments includes contiguous zeros, if the second segment includes contiguous zeros determining a number of contiguous zeros, determining a first skip level using the number of contiguous zeros, and inserting the first skip level into the first trie node.
