Abstract
An address information searching system includes a high frequency address table, a low frequency address table, and a searching unit. Each of the high and low address tables stores address information including a node address, a branch address, and time data representing an elapsed time from a timing at which the addresses are registered or referred to. In order to transmit data to a trunk network or an intra-branch-network, the high frequency address table is first referred to search for object address information. When the object address information is not registered in the high frequency address table, the low frequency address table is referred to search the address information. It is determined that the object address information is registered in the high or low frequency address tables as a result of searching performed, time data of the object address information is reset the high and low frequency address tables are accessed at a substantially predetermined period, and the time data of each address information is incremented.
