Issues Descriptions

Minor clarifications and enhancements

  • Key: DDSTSN-3
  • Status: closed  
  • Source: Real-Time Innovations ( Mr. Fernando Garcia-Aranda)
  • Summary:

    In Clause 7.2.2, the term "network topology description" seems odd. The text should probably refer to the deployment configuration model.

    In Table 7.19, "DataFrameSpecification Definition", the second bullet point should only refer to UDP/IP, not "TCP/IP".

    In Clause 8.2.2 should clarify that endpoints in the context of DDS entities refer to DataReaders and DataWriters, the term may confuse readers coming from different backgrounds.

    In Clause B.1.2, the clarification on manual configurations that need to calculate a schedule should probably mention they need to calculate whether the requirements can be met (schedule may be a confusing term in that context).

    In B.2.1.1, "Square Stream Configuration", the destination-mac-address in the status response should be "01-00-5E-7F-FF-01" (given the destination multicast IP address).

    In B.2.1.2, "Triangle Stream Configuration", the destination-mac-address in the status response should be "01-00-5E-7F-FF-02" (given the destination multicast IP address).

Update references to 802.1Qcc and 802.1Qcr, which have been merged into 802.1Q

  • Summary:

    IEEE 802.1Q has recently (as of 2022) incorporated several specifications that have been developed in parallel. That is the case of 802.1Qcc, which this specification heavily relies on, and 802.1Qcr. This is part of the regular process of IEEE.

    At the time of publication of the revised submission, 802.1Q-2022 was being voted and finalized, so the Beta 1 version of DDS-TSN points to 802.1Q-2018, 802.1Qcc, and 802.1Qcr. We should update these references and point to 802.1Q-2022, which now includes both Qcc and Qcr.

  • Disposition Summary:

    Update references to 802.1Qcc and 802.1Qcr

    As part of this resolution, we update references to 802.1Qcc and 802.1Qcr with references to IEEE 802.1Q (2022), which has merged these specifications into the core document.
