UCI – provides users with an
interface to interact with CVM.
SE – contains algorithms to
automatically synthesize a user
communication schema instance
to an executable form
(communication control script)
UCM – executes communication
control script and manages the
delivery of communication
services.
NCB – provides an API to the
UCM and delivers communication
services.

Policies



A policy is a set of considerations designed to guide
decisions on courses of action.
They are rules that define the choices in the
behavior of a system.
They include 4 common elements:[3]
–
–
–
–
16
Scope: what is or is not the subject of the policy
Condition: when a policy is to be applied
Business Value: labels relative priority allowing to make
economic trade-offs.
Decision: describes desired outcome of a policy
