Abstract: In a provisioning control apparatus which performs provisioning of network devices in order to construct a predetermined network architecture on a network composed of the network devices, a command generator generates a network setup command for making the predetermined network architecture to be provided to the network devices, a network status analyzer acquires operation status information of the network devices determined based on the setup result, and analyzes a network architecture state based on operation status information. A provisioning controller determines the network setup command based on the analysis result and demands the command generator to generate the command.
