Abstract
A communication device includes: an address administration unit that manages data link layer addresses; and an ARP processing unit that processes an ARP protocol. The ARP processing unit includes an ARP receiving unit, an ARP transmitting unit, a duplication detecting unit, a duplication notification generating unit and an update GARP generating unit. The update GARP generating unit transmits a GARP and thereby updates the ARP tables of the communication devices on the same network, in order to solve a problem in which communication is interrupted.
