Once validated and corrected for any conflicts, the policies are placed in an appropriate repository, and are made available to the other subsystems and components that might make use of them. In addition, the decisions and actions taken by the policy are distributed. Policies are distributed either in conjunction with installation packages (if for example, the policy is related to service instantiation) or independently, if the policy is unrelated to a particular service.  With this methodology, policies will already be available when needed by a component, minimizing real-time requests to a central policy engine or PDP (Policy Decision Point). This improves scalability and reduces latency.

Policy designers and administrators can use the Policy Manager feature of the OpenECOMP Portal to create, modify, and manage policies.

Policy Creation

The Policy Creation component of the Policy subsystem enables creation of new policies and modification of existing polices, both online and offline. <<There seems to be a "Policy application"  based on the ECOMP User Guide.  Will this be part of first release of OpenECOMP?  Is that really the name of it, "Policy application"?  Is this app/UI part of another UI like Portal?>>

 Once policies are created, Policy Creation also provides Policy Creation also provides additional functionality once policies are initially created:

• Offline analysis of performance, fault, and closed-loop actions, enabling the discovery of new and signatures and refinement of existing ones
• Derivation of lower-level policies from higher-level policies
• Identification of conflicts and mitigation of them before deployment
