Abstract
The control unit specifies an undetected connection destination port and sends a reply request to a connection destination of the undetected connection destination port. The packet transfer unit determines whether the received reply request is to be transferred to any other packet transfer unit. The packet transfer unit, upon determining the reply request to be transferred to any other packet transfer unit, transfers the reply request to any other packet transfer unit. The packet transfer unit, upon determining the reply request not to be transferred to any other packet transfer unit, returns a reply that includes information on ports of the local packet transfer unit, the reply being sent along a path leading to the control unit.
