Abstract
A gateway apparatus for performing transfer control of frame data between communication channels includes a routing map that stores ID information about the frame data and information about a communication channel that uses the ID information, and a search engine unit that routes the frame data to a transfer destination on the basis of the ID information of the frame data received and the routing map. The search engine unit does not transfer the frame data to the transfer destination when the ID information about the frame data received is ID information that is not used in the communication channel through which the frame data is received.
