PURPOSE: To execute a multi-path control consisting of plural sets of switch adaptors and one set of plug socket adaptor by providing a multi-path mode on the switch adaptor so that a packet from a transmitting destination which is set to the output party address setting part of the own station can also be received.
CONSTITUTION: As for a control from switch adaptors 2a, 2b of a multi-path mode, the other party address information 25 of a packet 23 notified from a plug socket adaptor 3a by a state variation of a load 4a decides information of the other party address setting part 16 of the switch adaptor 2a, and in order to allow them to coincide, the switch adaptor 2a receives the packet 23 and outputs data information 27 to an output interface part 20. On the other hand, the switch adaptor 2b decides the other party address information 25 of the packet 23 and information of the other party address setting part 16, but they do not coincide in this case, therefore, the other party address setting part 16 and the other party address information 25 of the packet 23 are decided, and since they coincide in this case, the packet 23 is received and the data information 27 is outputted to the output interface part 20.
