Goal

A system process authenticates and performs some system operation (e.g. replication). In this example, a Member Node authenticates to enable transfer of content from MN A to MN B.

Summary

System operations are required for many operations including the management of content across Member Nodes and replication between Coordinating Nodes. This use case describes the system level interactions required to perform a system level operation.

Actors

• Coordinating Node
• Member Node(s)

Preconditions

• Operational system

Triggers

• A system level operation is invoked.

Post Conditions

• The operation is completed
• The authentication token is optionally disposed
