This QosPolicy can be used by a DDS implementation to change how it processes and sends data that has low latency requirements. The DDS specification does not mandate whether or how this parameter is used. Connext DDS uses it to prioritize the sending of asynchronously published data; see ASYNCHRONOUS_PUBLISHER QosPolicy (DDS Extension).
This QosPolicy also applies to Topics. The Topic’s setting for the policy is ignored unless you explicitly make the DataWriter use it.
It contains the single member listed in DDS_LatencyBudgetQosPolicy.
