<p><P>PROBLEM TO BE SOLVED: To provide a packet transfer device which minimizes deterioration of packet transfer performance when filtering is executed. <P>SOLUTION: A destination judgment processing part 120 of a filtering means 100 which is destination judgment judges presence/absence of execution of the filtering from at least one piece of information among an input interface, an input line number, an output interface, an output line number and a plurality of pieces of information constituting a header of the packet. A filtering part 110 executes the filtering only to the packet judged to be executed. Since it is unnecessary the the packet transfer device having the filtering means 100 which is the destination judgment executes the filtering to all the packets, the packet transfer device suppresses the deterioration of the packet transfer performance by the execution of the filtering to minimum. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
