Abstract

The invention provides a method and system for rapid lookup and update (for example, of message header information) that records information in a database in a compact structure. The database includes a hybrid trie structure (100), wherein information in the denser portions of the database can be stored and retrieved from an identifiable leaf in the trie (100) and information in the sparser portions of the database can be stored and retrieved from a table. The hybrid trie (100) is recorded in a sequence of SRAM memories (210) so that a sequence of lookup requests can proceed in a pipelined manner with all the memories performing concurrent lookups so that the lookups can be performed at a rate substantially equal to their arrival rate.
