Abstract
[Problem] A lead time for providing a network service can be shortened.[Solution] A network service management apparatus 100 that uses resources included in a network functions virtualization infrastructure 140 to provide a network service includes an orchestrator 110 that defines resources that satisfy a resource requirement of a virtual network function constituting the network service and are allocated to the virtual network function, and reserves the resources, and a virtualized infrastructure manager 130 that secures the reserved resources, activates the virtual network function on the secured resources, and generates the network service. When the securing of the reserved resources fails, the orchestrator 110 re-reserves resources to replace the reserved resources, and the virtualized infrastructure manager 130 secures the re-reserved resources, and activates the virtual network functions on the secured resources.
