1. A controller comprising:
physical network information acquisition circuitry to obtain information about resource of a device and information about connection between devices in a wireless access network;
physical path calculation circuitry to calculate physical path resource information based on the information about resource of the device and on the information about connection between the devices, the physical path resource information being information about resource of a physical path between the devices;
abstract path resource calculation circuitry to calculate abstract path resource information based on the physical path resource information, the abstract path resource information representing representative of the physical path resource information;
abstract path correlation calculation circuitry to generate correlation information based on the abstract path resource information and on link information associated with information about resource extracted as the abstract path resource information, the correlation information being information about correlation between abstract paths;
a resource pool to store the abstract path resource information and the correlation information;
a temporary resource pool to temporarily store the abstract path resource information and the correlation information, each being information stored in the resource pool;
abstract resource allocation circuitry to determine, upon reception of a slice request, whether a slice meeting a requirement is capable of being generated, based on information stored in the temporary resource pool, and to issue an instruction to reserve a physical path when determining that a slice meeting the requirement is capable of being generated; and
temporary resource calculation circuitry to update the information in the temporary resource pool based on an abstract resource allocated to the slice from the abstract path by the abstract resource allocation circuitry.
