Abstract:
A method of controlling traffic loading on a cable modem termination system (CMTS) having a plurality of basic upstream data service flow scheduling types for a cable data system, comprised of the steps of:determining available bandwidth on an upstream cable data system channel; determining one of the plurality of basic data service flow scheduling types of a requesting subscriber; determining how much of the available bandwidth on said upstream cable data system channel can be allocated to said data service flow scheduling type; comparing the available bandwidth on an upstream cable data system channel to the bandwidth to be allocated by the CMIS to the requesting subscriber based upon the type of basic upstream data service flow scheduling type to be allocated to said requesting subscriber; determining whether the available bandwidth is greater than, less than or equal to the bandwidth to be allocated by the CMTS to the requesting subscriber for the basic upstream cable data system service flow scheduling type to be allocated for the requesting subscriber; granting or denying cable data service to said requesting subscriber based upon the determining of whether the available bandwidth is greater than, less than or equal to the bandwidth to be allocated to the requesting subscriber; and assigning the requesting subscriber to a different cable data system upstream channel with more available capacity when the available bandwidth on the requested cable data system upstream channel is less than the bandwidth to be allocated to the requesting subscriber.
