Logical Endpoint Traceability

Return to L Terms

Discussion

Logical Endpoint Traceability relates a Logical Communication Endpoint to its participating Logical Nodes, Communication Roles, Logical Data Structure Definitions, Runtime Plane classification, governance constraints, and evidence expectations.

Logical Endpoint Traceability supports review of information movement. It identifies which Logical Nodes produce information, which Logical Nodes consume information, which information structures the endpoint carries, which Runtime Plane frames the exchange, and which constraints or evidence expectations apply.

Logical Endpoint Traceability also protects the distinction between logical endpoints and implementation mechanisms. A later implementation profile maps a Logical Communication Endpoint to a selected technology, but the logical endpoint remains the architectural relationship to trace.

Definition

Traceability relationship connecting a Logical Communication Endpoint to participating Nodes, Communication Roles, information structures, Runtime Planes, governance constraints, and evidence expectations.

Source

Specialisation of Communication Endpoint, Runtime Plane, Data Structure Definition, Traceability, and Evidence from Part 1, Sections 7.6, 7.5, 7.7, 7.10, and 7.9; generalised from endpoint, topic, publish/subscribe, and interaction material in the original FX Demo Reference Architecture.

Note

Logical Endpoint Traceability does not imply a DDS Topic, REST resource, RPC method, message queue, event stream, file, or network route.

Example

A logical Node Status endpoint traces to reporting Logical Nodes, the Health Monitoring Node, the Node Status definition, the Logical Health and Observability Plane, and evidence expectations for operational review.
