Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 4:
5. A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations of an information and communication technology (ICT) resource management device that manages a physical node and a virtual node as ICT resources, the operations comprising:
collecting physical layer configuration information and virtual layer configuration information, wherein the physical layer configuration information is information on a configuration of the physical node in a physical layer and the virtual layer configuration information is information on a configuration of the virtual node in a virtual layer;
selecting, in response to a request for a configuration change concerning a connection of a device that uses a service to the physical node, a service infrastructure that meets a condition included in the request from a plurality of service infrastructures that realize the service;
performing a mapping between the physical layer and the virtual layer;
creating, in response to the request for a configuration change, a blueprint based on the physical layer configuration information, the virtual layer configuration information, the selected service infrastructure, and mapping information that results from the mapping, wherein the blueprint is design information of an infrastructure that is required for the configuration change; and
performing, based on the blueprint, orchestration of the virtual layer by accessing and executing a program that is capable of being operated through an API.
