Return to Requirements

Topic implementation traceability SHALL relate FX logical Communication Endpoints to DDS Topics.

Part 4, Section 21.14: Implementation Traceability Requirements.

DDS Topics provide the selected Phase 0 implementation realization of FX logical Communication Endpoints.

Explicit Topic traceability allows reviewers to determine which logical endpoint a DDS Topic realizes while preserving the distinction between the logical communication definition and its DDS implementation mechanism.

This requirement applies to:

• FX logical Communication Endpoints;
• DDS Topics;
• Topic mappings; and
• associated implementation participants and configuration.

Verification SHALL confirm that Topic implementation traceability relates FX logical Communication Endpoints to DDS Topics.

Verification activities should include review checks confirming that:

• each governed DDS Topic mapping identifies its logical endpoint;
• each implemented endpoint has an identifiable DDS Topic mapping;
• mappings are reviewable in both directions; and
• DDS Topics do not redefine their logical endpoints.

This requirement establishes implementation traceability between FX logical Communication Endpoints and their Phase 0 DDS Topic realizations.
