return to the Quality of Service (QoS) Parameters

The LATENCY_BUDGET policy provides a means for the application to indicate to the middleware the “urgency” of the data-communication. By having a non-zero duration the Service can optimize its internal operation.

This policy is considered a hint. There is no specified mechanism as to how the service should take advantage of this hint.

The value offered is considered compatible with the value requested if and only if the inequality “offered duration ⇐ requested duration” evaluates to TRUE.
