Balance Template AQM Reservations Properties

AQM reservation properties specify how balance reservations are handled during quota authorization for balances impacted by services that use the Balance Accuracy Feedback (BAF) feature, and, optionally, the Adaptive Quota Management (AQM) feature.

AQM Reservations Properties lists the AQM reservations properties.

Table 1. AQM Reservations Properties
Property Description
Max Reservation Time (seconds) The maximum number of seconds for which a reservation is valid. If AQM is enabled, this value is used to shape the quota size and validity time.
Max Per Context Reserved Amount The maximum amount of this balance, periodic balance entry, or meter, which can be reserved by any one service context per session. This allows providers to allow allocating a maximum percentage of the remaining asset to a session.
Max Total Reserved Amount The maximum amount that can be reserved against this balance or meter by all service contexts in a session. This value acts as a credit limit that rejects any usage that exceeds this total reserved amount.
Adaptive Threshold Scale Factor Used with AQM and the Balance Threshold Feedback (BTF) feature, which calculates the available quantity until the next threshold is reached.

The scale factor controls the distance before a threshold at which the quota drops from default authorization or reauthorization values to the minimum authorization or reauthorization values. For example, a value of 2 makes it appear that subscribers are two times closer to the threshold than they are, this causes AQM to start issuing smaller quotas twice as early as it otherwise would, and it does so more gradually because it has more time to slow down.
