Abstract

The communication device comprises a first table that stores a first entry in which a match condition that includes at least a destination address is associated with an output destination of a packet matching the match condition; a second table that stores a second entry having a predetermined match condition; a destination learning unit that registers a set of a source and a receiving port of a received packet as a match condition and an output destination, respectively, in the first table; and a packet processing unit that forwards a packet to an output destination determined in the first table when an entry having a match condition matching a received packet is found from each of the first and second tables. The packet processing unit broadcasts a received packet according to a third entry when no entry having a match condition matching the received packet is found.
