12.7 Traceability from Part 1 to Part 2

Go to Top

Part 2 should maintain explicit Traceability to Part 1.

Traceability from each major logical element to its conceptual source allows reviewers to verify that the logical architecture preserves the conceptual architecture and prepares a clear basis for implementation profiles, deployment profiles, and Evidence plans.

Table 12.7-1 provides examples of Traceability from Part 1 concepts to Part 2 logical elements.

Table 12.7-1: Examples of traceability from conceptual elements to logical elements

Node	Logical Node
Node Identity	Logical identity model for Nodes

Runtime Plane	Logical plane model and plane participation rules
Communication Endpoint	Logical endpoint or interaction point
Data Structure Definition	Logical information structure
