DYNAMIC SERVICE FLOW CREATION FOR PACKET CABLE QUALITY OF SERVICE GUARANTEE IN A DISTRIBUTED CABLE MANAGEMENT SYSTEM

摘要

Some embodiments provide a method for dynamically creating a 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 to create a set of parameters for a service flow that is to be dynamically created. In some embodiments, the received request is in response to a request for a phone call that is to have a quality of service (QoS) guarantee and the service flow is for a PacketCable (PC) connection session. For the service-flow parameter request, the method identifies the EN that connects to the particular service node from a group of several EN that the method manages. The method then forwards a set of authorized dynamic QoS (DQoS) parameters to the identified EN, so that the identified EN can use the forwarded DQoS parameter set to validate a service flow request from the particular device to the EN to create the service flow. The forwarded DQoS parameter set is part of a pre service-flow request that the method sends to the identified EN in some embodiments to direct the identified EN to prepare for a possible service flow request from the particular device.
