Abstract
A network address management unit () allocates, to the first edge node, a first network address () on which a physical configuration of a first edge node () is reflected. The network address management unit, when a second edge node () is coupled to the first edge node, allocates, to the first edge node, a second network address () on which the physical configuration of the first edge node is reflected with respect to the second edge node. When the first edge node receives a packet that designates the first or second network address as a destination network address, the first edge node, based on the destination network address designated by the received packet, determines whether the received packet is transferred to the second edge node and discriminates a transfer destination path in the first edge node.
