1. An interconnection device for interconnecting a plurality of network devices, comprising:
- a plurality of ports, each of which is connectable to a network device;
a plurality of address tables corresponding to respective ones of the plurality of ports, wherein each of the plurality of address tables stores address information of a network device connected to a corresponding port and address management information on a packet sent out from the corresponding port; and
a controller controlling each of the plurality of address tables such that address information of a network device is set when the network device is connected to a corresponding port, and controlling transfer of a packet arriving at a port to an appropriate one of the plurality of ports by referring to the plurality of address tables and setting address management information on the packet.

Abstract
An interconnection device has a plurality of address tables corresponding to respective ones of a plurality of ports. Each address table stores address information of a network device connected to a corresponding port and address management information on a packet sent out from the corresponding port. When a network device is newly connected to a port, address information of the network device is set in a corresponding address table. A packet arriving at a port is forwarded to a selected port by referring to the plurality of address tables and setting address management information on the packet.

11. A control method of an interconnection device for interconnecting a plurality of network devices, wherein the interconnection device has a plurality of ports, each of which is connectable to a network device, the method comprising:
-
a) determining whether a network device is connected to each of the plurality of ports;
b) when it is determined that a network device is connected to a port, acquiring address information of the network device connected to the port;
c) storing address information of network devices connected to a plurality of ports into a plurality of address tables each corresponding to the plurality of ports;
d) when receiving a packet at a port, selecting an appropriate one of the plurality of ports by referring to the plurality of address tables;
e) storing address management information on the packet into an address table corresponding to a selected port; and
f) sending the packet from the selected port. - View Dependent Claims (12, 13, 14, 15, 16)

17. A program product including a computer-readable program which instructs a computer to control an interconnection device for interconnecting a plurality of network devices, wherein the interconnection device has a plurality of ports, each of which is connectable to a network device, the program comprising the steps of:
-
a) determining whether a network device is connected to each of the plurality of ports;
b) when it is determined that a network device is connected to a port, acquiring address information of the network device connected to the port;
c) storing address information of network devices connected to a plurality of ports into a plurality of address tables each corresponding to the plurality of ports;
d) when receiving a packet at a port, selecting an appropriate one of the plurality of ports by referring to the plurality of address tables;
e) storing address management information on the packet into an address table corresponding to a selected port; and
f) sending the packet from the selected port.
