Cisco Policy Suite (CPS) provides a framework for building rules that can be used to enforce business logic against policy enforcement points such as network routers and packet data gateways. For example, a prepaid customer (one who pays as they go) might be denied service or prompted to top-up when their quota has expired, whereas a postpaid customer (one who has an ongoing billing relationship with the service provider) might only have their service downgraded or be automatically billed for additional data when their particular quota has expired.
CPS allows service providers to create policies that are customized to their particular business requirements through the use of the CPS Policy Builder, a web-based tool with a graphical user interface (GUI) that allows for rapid development of innovative new services.
The Policy Builder GUI supports both configuration of the overall CPS cluster of virtual machines (VMs) as well as the configuration of services and advanced policy rules. The following sections introduces the main aspects of the PB GUI as laid out in three tabs on the upper right of the interface: Reference Data, Services and Policies.
