Status propagation models

A propagation model defines how the status of a provider component must be propagated in an impact relationship based on the following details:

  • The current state of the relationship
  • The current value of the provider's status

Status propagation models are used only by impact relationships.

Status propagation models serve the following purposes:

  • Relationship control–Enforcement of logical rules in creating new component relationships so that only valid relationships are created
  • Dynamic status mapping–Translating the main status of the provider component into a propagated status for input into the impact_function of the consumer component in a relationship
     The impact_function is part of the status computation of a component. For more information, see Anatomy of a status computation model.
