===== Statement =====

The Phase 0 Implementation Profile / PSM SHALL identify DDS as the selected Phase 0 communication technology.

===== Source =====

Part 4, Section 21.3: Technology Selection Requirements.

===== Rationale =====

DDS provides the selected communication mechanism through which Phase 0 implementation participants realise applicable FX logical Communication Endpoints and interaction flows.

Explicitly identifying DDS as the Phase 0 communication technology establishes a controlled communication baseline while preserving the distinction between logical communication and its implementation realisation.

===== Applies To =====

This requirement applies to:

  * Phase 0 implementation participants;
  * DDS Topics;
  * publishers and subscribers;
  * communication configuration; and
  * FX logical Communication Endpoint mappings.

===== Verification =====

Verification SHALL confirm that DDS is identified as the selected Phase 0 communication technology.

Verification activities should include review checks confirming that:

  * Phase 0 communication mappings use DDS where required by the implementation baseline;
  * DDS Topics realise selected FX logical Communication Endpoints;
  * implementation participants use the applicable DDS communication mechanisms; and
  * DDS usage remains distinguishable from the logical endpoint definitions.

===== Traceability =====

This requirement establishes the Phase 0 communication-technology realisation of selected FX logical Communication Endpoints.
