JPS Framework
Figure 1 depicts the PCMM architectural framework. The JPS communicates with application managers, CMTS devices, and record-keeping servers.
Figure 1: PCMM Architectural Framework
The interactions between the various PCMM components are centered on the policy server. In the PCMM architecture, these basic interactions occur:
- A client requests a multimedia service from an application manager.
- Depending on the client type and its QoS signaling capabilities, the application manager relays the request to a policy server.
- The policy server relays the request to the CMTS device
and is responsible for provisioning the policies on a CMTS device.
Depending on the request, the policy server records an event for the policy request and provides that information to the record-keeping server (RKS).
- The CMTS device performs admission control and manages network resources through Data over Cable Service Interface Specifications (DOCSIS) service flows based on the provisioned policies.
- The RKS receives event messages from other network elements, such as the policy server or CMTS device, and acts as a short-term repository for the messages.
