<p>PROBLEM TO BE SOLVED: To virtually form a server for federation control on a slice and to create a user slice over domains of other virtualization bases while using the virtual server.SOLUTION: On an administrative slice created beforehand on a virtual network over a plurality of virtualization bases, a virtual node within one virtualization base and a virtual node within another virtualization base are formed and connected by a link, and a first virtual server is formed that performs the virtual nodes created on the virtualization bases, configuration definition information of a virtual network to be created on the other virtualization base is held in a nest structure. When creating a second slice on a virtual network over the one virtualization base and the other virtualization base, the first virtual server formed in the administrative slice instructs the creation of the second slice on the other virtualization base while using the configuration definition information acquired from the specific virtual node.</p> |
