Controlling the cable modem termination system

OpenDaylight's PacketCable Multimedia (PCMM) project is an interface that lets you control and manage service flow for cable modem termination system (CMTS) network elements. The service flow enables a dynamic quality of service (DQoS) between a CMTS and a cable modem (CM) using the Data Over Cable Service Interface Specification (DOCSIS) standard. The project is composed of a policy server allocating network resources per subscriber and application, an application manager specifying QoS requirements per-application to the policy server, a CMTS enforcing the policies based on bandwidth capacity, and a CM connecting to the client's network (cable system).
