DYNAMIC SERVICE FLOW CREATION FOR PACKET CABLE MULTIMEDIA QOS GUARANTEE IN A DISTRIBUTED CABLE MANAGEMENT SYSTEM

摘要

A method for dynamically creating service flow for an Ethernet node (EN) in a distributed cable management system that includes a cable headend and several in-the-field ENs for connecting several service nodes to the headend. For a particular device of a particular service node, the method receives a request for a Packet Cable Multi-Media (PCMM) connection session with a quality of service (QoS) guarantee. For the request, the method identifies the connected EN from a group of several managed EN, then forwards a set of authorized dynamic QoS (DQoS) parameters to the identified EN, which then uses the forwarded parameter set to create a service flow for the particular device. In some embodiments, the identified EN creates two service flows for two different directions of traffic associated with the particular device at the particular service node. Specifically, the EN creates an upstream/downstream service flow for the upstream/downstream data traffic respectively.
