Return to Requirements

A Communication Role SHALL identify how a Logical Node participates in a Logical Communication Endpoint.

Part 2, Section 16.4: Logical Communication Requirements.

Communication Roles describe the manner in which Logical Nodes participate in logical exchanges. Separating participation from the endpoint itself provides a reusable and technology-independent means of modeling communication relationships while supporting multiple interaction patterns and architectural specialisations.

This requirement applies to the Logical Communication Model.

It applies specifically to:

• Communication Roles;
• Logical Nodes;
• Logical Communication Endpoints; and
• Logical Interaction Patterns.

Verification SHALL confirm that each Communication Role identifies how a Logical Node participates in a Logical Communication Endpoint.

Verification activities should include review checks confirming that:

• Communication Roles are explicitly associated with Logical Nodes;
• Communication Roles define participation in Logical Communication Endpoints;
• participation remains platform independent; and
• Communication Roles support the Logical Interaction Patterns defined by the architecture.

This requirement supports traceability between Logical Nodes, Communication Roles, Logical Communication Endpoints, and Logical Interaction Patterns.
