swagger: "2.0" info: version: "1.2.1-impl:etsi.org:ETSI_NFV_OpenAPI:1" title: SOL003 - Virtualised Resources Quota Available Notification interface description: > SOL003 - Virtualised Resources Quota Available Notification interface IMPORTANT: Please note that this file might be not aligned to the current version of the ETSI Group Specification it refers to. In case of discrepancies the published ETSI Group Specification takes precedence. In clause 4.3.2 of ETSI GS NFV-SOL 003 v2.4.1, an attribute-based filtering mechanism is defined. This mechanism is currently not included in the corresponding OpenAPI design for this GS version. Changes to the attribute-based filtering mechanism are being considered in v2.5.1 of this GS for inclusion in the corresponding future ETSI NFV OpenAPI design.

The POST method creates a new subscription. This method shall follow the provisions specified in the tables 11.4.2.3.1-1 and 11.4.2.3.1-2 for URI query parameters, request and response data structures, and response codes. As the result of successfully executing this method, a new "Individual subscription" resource as defined in clause 11.4.3 shall have been created. This method shall not trigger any notification. Creation of two "Individual subscription" resources with the same callbackURI and the same filter can result in performance degradation and will provide duplicates of notifications to the VNFM, and might make sense only in very rare use cases. Consequently, the NFVO may either allow creating a new "Individual subscription" resource if another "Individual subscription" resource with the same filter and callbackUri already exists (in which case it shall return the "201 Created" response code), or may decide to not create a duplicate "Individual subscription" resource (in which case it shall return a "303 See Other" response code referencing the existing "Individual subscription" resource with the same filter and callbackUri). parameters: - name: Accept description: > Content-Types that are acceptable for the response.

As the result of successfully executing this method, the "Individual subscription" resource shall not exist any longer. This means that no notifications for that subscription shall be sent to the formerly-subscribed API consumer.
