Abstract

An integrated search engine device evaluates span prefix masks for keys residing at leaf parent levels of a search tree to identify a longest prefix match to an applied search key. This longest prefix match resides at a leaf node of the search tree that is outside a search path of the search tree for the applied search key. The search engine device is also configured to read a bitmap associated with the leaf node to identify a pointer to associated data for the longest prefix match. The pointer has a value that is based on a position of a set bit within the bitmap that corresponds to a set bit within the span prefix mask that signifies the longest prefix match.
