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.

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 callback URI and

committed
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
callback URI already exists (in which case it shall return the "201 Created" response code),
moscatelli
committed
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 callback URI).

Query Subscription Information.
The GET method queries the list of active subscriptions of the functional block that invokes the method.
It can be used e.g. for resynchronization after error situations.
This method shall follow the provisions specified in the tables 11.4.2.3.2-1 and 11.4.2.3.2-2
for URI query parameters, request and response data structures, and response codes.

Query Subscription Information.
The GET method reads an individual subscription.
This method shall follow the provisions specified in the tables 11.4.3.3.2-1 and 11.4.3.3.2-2
for URI query parameters, request and response data structures, and response codes.

Terminate subscription.
The DELETE method terminates an individual subscription.
This method shall follow the provisions specified in the tables 11.4.3.3.5-1 and 11.4.3.3.5-2
for URI query parameters, request and response data structures, and response codes.
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.
NOTE: Due to race conditions, some notifications might still be received by the formerly-subscribed
API consumer for a certain time period after the deletion.
