Deadline QoS

Return to Glossary

Significant parameter for periodic and aperiodic real-time critical communications. This represents the maximum separation between two topic updates. The Data Writer indicates that the application commits to write a new value at least once every deadline period. The Data Readers are notified by the data_distribution_service_dds engine when the Deadline quality_of_service_qos_policies contract is violated.
