摘要： Service failure information can be quickly and accurately disseminated to appropriate targets. A service failure information dissemination system 1 receives alarm information notifying that a failure has occurred in a service or a device for providing a service and related information that relates to the alarm information, obtains the degree of influence of the failure for each service type based on the alarm information and the related information, determines a dissemination target and a dissemination means of failure information based on the degree of influence, creates failure information according to the dissemination means, and disseminates the failure information to the dissemination target through the dissemination means.

摘要： [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.

摘要： To appropriately exclude alarms not requiring maintenance operator confirmation. An alarm control device 1 includes: an individual filter determination unit 11 which acquires, from a storage unit, a determination condition (an individual filter) for whether or not maintenance operator confirmation corresponding to a device alarm issued from a network element device 2 is necessary; an alarm evaluation unit 12 which acquires information corresponding to a determination criterion of the determination condition from a management database 4 managing the network element device 2, checks the acquired information with the determination condition, and determines whether or not maintenance operator confirmation is necessary; and an alarm notification unit 13 which transmits a device alarm to a maintenance operator terminal 5 when the maintenance operator confirmation is determined to be necessary and does not transmit the device alarm to the maintenance operator terminal 5 when the maintenance operator confirmation is determined to be unnecessary.

摘要： [Problem] To improve performance of NS management.
[Solution] A management apparatus M for managing an NS constructed on an NW including a virtualization area and a non-virtualization area includes a request reception unit 11 configured to acquire an NS generation order including an input parameter required for designating a server-side apparatus and an NW-side apparatus, from an external apparatus, and a catalog DB 17 that stores a catalog serving as a template of the NS. The catalog includes an NSD being a portion in which a configuration of the NS is described and having a plurality of types of information sets defining a group of constituent elements of the NS in a selectable manner. The management apparatus M further includes a scenario management unit 12 configured to generate, if a specific parameter for individually designating a group of constituent elements of the NS by another system U1 without selecting the plurality of types of information sets is included in the input parameter, the NS by using the individually designated group of constituent components of the NS, and to otherwise generate the NS by using an information set selected by the other system U1.
