<P>PROBLEM TO BE SOLVED: To provide a method and the like not to allocate in duplication an IP address to be allocated to a node device, when setting a path through a plurality of network resource domains. <P>SOLUTION: Each resource management device includes an address resource storage which stores an IP address range allocatable to the node device in a network resource domain managed by the self-resource management device. A first resource management device accepts a path request for establishing a path between a first node device, subordinate to a first network resource domain, and a second node device subordinate to a second network resource domain. Next, the first resource management device exchanges a non-allocated IP address in a first address resource storage with a non-allocated IP address in a second address resource storage. Then, both resource management devices allocate mutually non-allocated IP addresses to network terminal points in the first node device and the second node device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
