DDS11 — (R#122) Missing QoS dependencies in table

  • Key: DDS11-60
  • Legacy Issue Number: 8398
  • Status: closed  
  • Source: Real-Time Innovations ( Dr. Gerardo Pardo-Castellote, Ph.D.)
  • Summary:

    A DataReader must specify a TimeBasedFilterQosPolicy::minimum_separation value that is less than or equal to its DeadlineQosPolicy::period value. (Otherwise, all matched DataWriters will be considered to miss every deadline.)
    There are dependencies among the fields of ResourceLimitsQosPolicy: max_samples >= max_samples_per_instance.
    The above dependencies are not made explicit in the specification.

    Proposed Resolution:
    The above dependencies should be made explicit in the QoS policy table in section 2.1.3.

    Proposed Revised Text:
    The following sentence should be added to the "Meaning" column of the "DEADLINE" row: "It is inconsistent for a DataReader to have a deadline period less than its TIME_BASED_FILTER's minimum_separation."

    The following sentence should be added to the "Meaning" column of the "TIME_BASED_FILTER" row: "It is inconsistent for a DataReader to have a minimum_separation longer than its deadline period."

    The following sentence should be added to the "Meaning" column of the "max_samples" row: "It is inconsistent for this value to be less than max_samples_per_instance."

    The following sentence should be added to the "Meaning" column of the "max_samples_per_instance" row: "It is inconsistent for this value to be greater than max_samples."
