摘要： A communication apparatus operates as a node of a network. The communication apparatus includes a port-state managing unit that updates, every time failure occurrence in the network is detected, state information indicating a state of the network, a database updating unit that updates, based on a transmission source address and a reception port of a received frame and the state information managed by the port-state managing unit, a database that determines an output port when a frame in which the transmission source address is a destination address is received, and an output-destination determining unit that determines an output port of the received frame by searching through the database using, as search keys, the destination address of the received frame and the state information managed by the port-state managing unit.

摘要： When a packet to a terminal is received from a terminal, a management communication processing unit transmits by broadcasting or multicasting to a network a destination information query packet for investigating a gateway device to which the terminal is connected, receives from a gateway device a destination information response packet for notifying that the terminal is connected to the gateway device, and updates a terminal information storage table based on the destination information response packet. When the terminal information storage table is erased, the history information exchange unit transmits by broadcasting or multicasting to the network a history information query packet for requesting to re-notify of the terminal that has been notified in the destination information response packet, receives from the gateway device a history information response packet for re-notifying of the terminal, and updates the terminal information storage table based on the history information response packet.
