Return to Part 1 Requirements

Statement

A Node Identity SHALL uniquely distinguish a Node within a defined architectural context.

Source

Part 1, Section 13.4: Core Conceptual Element Requirements.

Rationale

A Node Identity provides the conceptual basis for distinguishing one Node from another within a defined architectural context. Unique distinction supports governance, accountability, traceability, policy evaluation, evidence collection, and operational interpretation.

This requirement prevents ambiguity when the architecture refers to Nodes across diagrams, requirements, profiles, and later implementation mappings.

Applies To

This requirement applies to Node Identity definitions and references within the Conceptual Architecture.

It applies specifically to:

Node identificationArchitectural contextNode distinctionCross-reference consistencyTraceability involving Nodes

Verification

Verification SHALL confirm that each Node Identity uniquely distinguishes a Node within a defined architectural context.

Verification activities include review checks confirming that:

Node Identity has a defined architectural contextNode Identity distinguishes one Node from anotherNode Identity does not substitute for a runtime process identifierLater implementation identifiers map to Node Identity without redefining it

Traceability
