SYSTEM FOR TRANSMITTING A PACKET HAVING VARIABLE-LENGTH IDENTIFIER OF A HIERARCHICAL STRUCTURE TO ADAPT LONGEST-PREFIX-MATCH LOOKUP ENGINE FOR ACCEPTING VARIALBE-LENGTH IDENTIFIER OF HIERARCHICAL STRUCTURE

摘要

PURPOSE: A system for transmitting a packet having variable-length identifier of a hierarchical structure is provided to easily perform communication through a data network.;CONSTITUTION: A packet receiver(220) receives a packet having HSVLI(Hierarchical Structure Variable Length Identifier) from an input port. A converter(240) converts the HSVLI into fixed-length key. A transmission-information acquirer(260) acquires transmission-information based on one or more longest-prefix-matches using longest-prefix-match lookup engine by using the fixed-length key. A packet(280) transmits the packet to an output port based on the transmission information.;COPYRIGHT KIPO 2010
