Abstract
A multi-way tree data structure is provided that supports a longest match lookup. Data elements stored therein that have no overlapping prefixes are arranged in a standard B-tree arrangement. Data elements that have overlapping prefixes are arranged within the tree such that a respective one of these prefixes contains the prefixes of all such data elements that succeed it.
