[[dido:99_annexes:annex-d-requirements:part-02:start| Return to Requirements]]

===== Statement =====

The Logical Architecture / PIM SHALL distinguish [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Logical Communication Endpoints]] from DDS Topics, REST resources, RPC methods, Protocol Buffers services, message queues, event streams, files, database handoffs, shared-memory locations, network routes, and deployment artifacts.

===== Source =====

Part 2, Section 16.4: Logical Communication Requirements.

===== Rationale =====

Logical Communication Endpoints are architectural concepts that describe platform-independent information exchange. They must remain distinct from technology-specific communication mechanisms to preserve architectural meaning, implementation flexibility, and traceability across multiple Implementation Profiles.

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

This requirement applies to the Logical Communication Model, Implementation Profiles, and Deployment Profiles.

It applies specifically to:

  * Logical Communication Endpoints;
  * Communication technology mappings;
  * Implementation artifacts; and
  * Deployment artifacts.

===== Verification =====

Verification SHALL confirm that Logical Communication Endpoints remain distinct from technology-specific communication mechanisms.

Verification activities should include review checks confirming that:

  * Logical Communication Endpoints are not defined as implementation technologies;
  * communication technology selections are deferred to Implementation Profiles;
  * implementation mappings preserve the meaning of Logical Communication Endpoints; and
  * deployment artifacts do not redefine Logical Communication Endpoints.

===== Traceability =====

This requirement supports traceability between Logical Communication Endpoints and the implementation artifacts that realize them.
