State machine for providing dynamic quality of service in a cable network

摘要

A cable modem termination system includes a data over cable service interface specification (DOCSIS) subsystem that manages a flow associated with a gate and a gate manager (GM) that manages a state of the gate. When the flow is admitted by the DOCSIS subsystem, the DOCSIS subsystem signals to the GM to transition the state of the gate to a reserved state. The GM transitions the state of the gate to the reserved state when the DOCSIS subsystem signals to the GM to transition the state of the gate to the reserved state. When the flow is activated by the DOCSIS subsystem, the DOCSIS subsystem signals to the GM to transition the state of the gate to a committed state. The GM transitions the state of the gate to the committed state when the DOCSIS subsystem signals to the GM to transition the state of the gate to the committed state.
