Abstract
According to the present invention, there is provided a data transfer system using mobile IP in which transfer interruption is not caused even if an MH moves between FNs. A MAC bridge connected between FNs includes means responsive to an address registration request issued by an AP, for storing a combination of a MAC address of the MH and a receiving port, in a filtering DB; means for registering a relation of association of an address of a terminal accommodated in an FN with a connection port of an FN in which the terminal is accommodated, in the filtering DB; and means for referring to the filtering DB on the basis of the destination address of a frame input to each port, and transferring the frame to a predetermined port on the basis of a relation of association of the address with a port identifier.
