Abstract

The present invention reduces the number of entries retained in a communication node in a centralized control network and reduces the load on a control device. A communication node is provided with: a first table for storing a first entry in which a match condition that includes at least a destination address is associated with the output destination of a packet compatible with the match condition; a second table for storing a second entry having a prescribed match condition; a destination learning unit for recording a group composed of a transmission source and an inbound port of an inbound packet as a match condition and an output destination respectively of the first table; and a packet processing unit for transferring a packet to the output destination determined in the first table when entries having a match condition compatible with the inbound packet are found respectively from the first and second tables. The packet processing unit broadcasts the inbound packet according to a third entry when the entry having the match condition compatible with the inbound packet is not found.
