|Duration of the maximum acceptable delay. |
This policy is a hint to a DDS implementation; it can be used to change how it processes and sends data that has low latency requirements. The DDS specification does not mandate whether or how this policy is used.
duration, RTI Connext can optimize its internal operation.
RTI Connext uses it in conjunction with DDS_ASYNCHRONOUS_PUBLISH_MODE_QOS DDSDataWriter instances associated with a DDS_EDF_FLOW_CONTROLLER_SCHED_POLICY DDSFlowController only. Together with the time of write, DDS_LatencyBudgetQosPolicy::duration determines the deadline of each individual sample. RTI Connext uses this information to prioritize the sending of asynchronously published data; see DDS_AsynchronousPublisherQosPolicy.
Duration of the maximum acceptable delay.
[default] 0 (meaning minimize the delay)
