    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.

        Subscribe


        The POST method creates a new subscription. Creation of two 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 subscription resource
        if another 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 subscription resource (in
        which case it shall return a “303 See Other” response code referencing
        the existing subscription resource with the same filter and
        callbackUri).
