Abstract

A number of hash tables are accessed concurrently with a different computed index based on a single search key for each hash table. Each index identifies a location in one of the hash tables capable of storing at least one entry. If all indexed locations are used, the entries stored in the lookup table can be reordered so that the new entry can be inserted in one of the locations identified by the computed indexes.
