It is intended to provide a frame transfer apparatus for transferring an LLDP frame to reduce a traffic load of the LLDP frame periodically sent for survival confirmation. The frame transfer apparatus within a network sends the LLDP frame by converting a TTL of the LLDP frame to be transferred to its maximum value of 65535. Also, the frame transfer apparatus makes the survival confirmation for a terminal, and sends as proxy the LLDP frame in which the TTL is set to 0, in place of the terminal, at a moment of expiration of the TTL, whereby the disconnection of the terminal from the network is appropriately notified to the other terminals. Thereby, the load of the LLDP frame periodically sent for survival confirmation within the network can be reduced. |
