Network management apparatus, method, and program

A network management device comprising:

• a processor;
• and
• a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
• select a path of a physical layer between a start point and an end point of a network based on a first entity stored in a first storage device configured to store the first entity, the first entity representing an entity of an information object of the network;
• generate a second entity of a logical layer corresponding to the path of the physical layer selected based on a specification of the information object stored in a second storage device configured to store the specification;
• maintain a relationship with a third entity in an identical layer or a next lower layer when the second entity of the logical layer corresponding to the path of the physical layer selected by the path selection processing unit is generated, and
• generate the second entity of each logical layer corresponding to the path of the physical layer selected based on the held relationship.

A network management method that is performed by a network management device, the network management method comprising:

• performing path selection processing of selecting a path of a physical layer between a start point and an end point of a network based on a first entity stored in a first storage device configured to store the first entity, the first entity representing an entity of an information object of the network;
• performing entity generation processing of generating a second entity of a logical layer corresponding to the path of the physical layer selected in the path selection processing based on a specification of the information object stored in a second storage device configured to store the specification, wherein the second storage device stores, as the specification of the information object, information that defines a relationship between the physical layer and a logical layer that is a lowest layer and a relationship among a plurality of the logical layers including the lowest layer;
• acquiring, from the second storage device, a first specification of the logical layer that is the lowest layer defined as a higher layer than the physical layer in the path selected in the path selection processing;
• acquiring, from the second storage device, a second specification of a logical layer defined as a higher layer than the logical layer that is the lowest layer;
• and
• generating the second entity of each logical layer corresponding to the path of the physical layer selected in the path selection processing based on the first specification and/or the second specification that is acquired.

A network management method that is performed by a network management device, the network management method comprising:

• performing path selection processing of selecting a path of a physical layer between a start point and an end point of a network based on a first entity stored in a first storage device configured to store the first entity, the first entity representing an entity of an information object of the network;
• and
• performing entity generation processing of generating a second entity of a logical layer corresponding to the path of the physical layer selected in the path selection processing based on a specification of the information object stored in a second storage device configured to store the specification
• wherein the performing of the entity generation processing includes
• maintaining a relationship with a third entity in an identical layer or a next lower layer when the second entity of the logical layer corresponding to the path of the physical layer selected by the path selection processing unit is generated, and
• generating the second entity of each logical layer corresponding to the path of the physical layer selected in the path selection processing based on the maintained relationship.
