1. 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 the available bandwidth on an upstream cable data system channel;
determining data service flow scheduling type of a requesting subscriber;
determining the available bandwidth on said upstream cable data system channel that 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 CMTS 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 by 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; and
granting or denying cable data service to said requesting subscriber based upon the determination of whether the available bandwidth is greater than, less than or equal to the bandwidth to be allocated to the requesting subscriber.

Abstract
A method and apparatus for providing connection admission control (CAC) on a cable data system helps provide viable quality of service (QoS) capability on a cable data system. Cable data service is granted or denied to cable data service to said requesting subscriber based in part upon the determination of whether the available bandwidth is greater than, less than or equal to the bandwidth to be allocated to the requesting subscriber.

10. A system for 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, comprising:
-
mean for determining the available bandwidth on an upstream cable data system channel;
means for determining data service flow scheduling type of a requesting subscriber;
means for determining the available bandwidth on said upstream cable data system channel that can be allocated to said cable data system service flow scheduling type;
means for comparing the available bandwidth on an upstream cable data system channel to the bandwidth to be allocated by the CMTS to the requesting subscriber based upon the type of basic upstream data service flow scheduling type to be allocated to said requesting subscriber;
means for determining whether by 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; and
means for granting or denying cable data service to said requesting subscriber based upon the determination of whether the available bandwidth is greater than, less than or equal to the bandwidth to be allocated to the requesting subscriber. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
