摘要

PROBLEM TO BE SOLVED: To contribute to reduction in power consumption or a processing load of a network and a communication device including an associative memory.SOLUTION: A communication device comprises: a table constituted by a plurality of associative memory blocks; a selection unit for determining, on the basis of area designation information attached to a reception packet, an associative memory block for searching for an entry having a matching condition suitable for the reception packet; and a packet processing unit that determines a processing content to be applied to the reception packet by referring to the associative memory block selected by the selection unit and processes the reception packet. A controller comprises: a first control unit for instructing a device on the upstream side from the communication device to attach the area designation information to the corresponding packet; and a second control unit that creates an entry to be set to the associative memory block of the communication device and instructs the communication device to set the entry to an associative memory block corresponding to the area designation information.SELECTED DRAWING: Figure 1
