16.3 Logical Node Requirements

Go To Top

The Logical Architecture / PIM SHALL define Logical Node, Logical Node Identity, Logical Node Role, Logical Node Responsibility, Logical Node Boundary, Logical Node Collaboration, and Logical Node Lifecycle State.A Logical Node SHALL represent a platform-independent participant in the distributed logical architecture.A Logical Node Identity SHALL uniquely distinguish a Logical Node within the Logical Architecture / PIM.A Logical Node Role SHALL identify a platform-independent responsibility assigned to or performed by a Logical Node.A Logical Node Responsibility SHALL describe an obligation, function, or accountability associated with a Logical Node or Logical Node Role.A Logical Node Boundary SHALL identify what the logical architecture treats as inside or outside a Logical Node for responsibility, interaction, Traceability, and review.Logical Node Collaboration SHALL identify explicit logical cooperation among Logical Nodes through Communication Endpoints and interaction patterns.Logical Node Lifecycle State SHALL identify the logical operational condition associated with a Logical Node.The Logical Architecture / PIM SHALL distinguish a Logical Node from a process, service, container, pod, virtual machine, serverless function, thread, task, library, subroutine, RPC endpoint, REST resource, DDS participant, and deployment artefact.
