System and method for a managed network with quality-of-service management

Abstract

Systems and methods for establishing Parameterized QoS flows in a managed network can include a Designated Network Node (like a Network Controller or any network node) discovering a plurality of network nodes. The Designated Network Node discovering one or more of the plurality of network nodes; classifying the discovered network node or nodes based on node type; determining from the classification which node or nodes are designated for supporting Parameterized QoS flows; and invoking a request to a MoCA layer to create Parameterized QoS flows between the network node or nodes classified as designated for Parameterized QoS flows and the source nodes (like BHR and DVRs); wherein the bandwidth designated for the individual Parameterized QoS flows is either a nominal value or actual value specified by the Designated Network Node such that the actual aggregate bandwidth for the Parameterized QoS flows does not exceed the network bandwidth available for actual Parameterized QoS flows; wherein when actual bandwidth is specified for each flow, the Designated Network Node can preempt some PQoS flows in order to release PQoS bandwidth for a new PQOS flow; wherein the Designated Network Node is provisioned with a trusted device list designating nodes for supporting PQoS flows, and preemption rules that can be used for preemption.
