In asynchronous processing, processing of a low-order system is checked. A high-order systemincludes a high-order workflow advancing unitthat transmits a processing command for asynchronous processing to a low-order system, and a notice processing unitthat receives, from the low-order system, a notice related to a device command to be executed by a devicein the asynchronous processing, and updates progress data. The low-order systemincludes a low-order workflow advancing unitthat, upon receiving the processing command from the high-order system, transmits a device command to the device, and a notification unitthat, when transmission of the device command to the deviceis detected, notifies the high-order systemof the identifier of the device to which the device command was transmitted and the device command.

An operation apparatus for outputting a request to a management apparatus which manages a Network Service (NS) constructed on a NetWork (NW) including a core NW serving as a virtualization area and an access NW serving as a non-virtualization area including: a storage unit configured to store new configuration information obtained by updating NW configuration information indicating an NW configuration including devices disposed on the NW due to a fault of the NS, a catalog which is a template of the NS, a record describing a lifecycle of the NS, and an order for requesting the management apparatus to control the NS; an optimal configuration determination unit configured to determine an optimal configuration of the NS based on the new configuration information, the catalog, the record, and the order; and an order generation unit configured to generate a change order for changing an NS configuration of the NS to the optimal configuration determined by the optimal configuration determination unit.

Operation device and operation method

A management apparatus is configured to manage a network service (NS) constructed on a network (NW) including a core NW configured to serve as a virtualization area and an access NW configured to serve as a non-virtualization area includes an E2EO configured to control the NS, an SVRO configured to control server-type apparatuses located on the NW, and a NWRO configured to control NW-type apparatuses located on the NW. The E2EO includes a single data center (DC) determination unit configured to determine whether a group of apparatuses used for providing the NS is located in a single DC. The group of apparatuses is designated by an order acquired from an upper level apparatus U. Among the NW-type apparatuses, ToRs located in the DC are controlled by the SVRO, instead of by the NWRO, when it is determined that the group of apparatuses is located in the single DC.
