First Claim
Patent Images
1. A method of controlling traffic loading on a cable modem termination system (CMTS) for a cable data system, comprising the steps of:
- determining the available bandwidth on a requested cable data system channel;
comparing the available bandwidth on the requested cable data system channel to bandwidth being request by a new subscriber;
determining whether the available bandwidth is greater than, less than or equal to the bandwidth to be allocated by the CMTS to the new subscriber; and
granting or denying cable data service to the new 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 new subscriber.

Abstract
A method and apparatus for controlling traffic loading on a cable modem termination system helps provide viable quality of service (QoS) capability on a cable data system. Available data bandwidth on a particular channel is first determined, followed by a comparison of the amount of bandwidth requested by, or required by a new subscriber. If the bandwidth available on a particular channel is adequate, service can be provided on the channel, otherwise the new subscriber is assigned to a new channel to avoid data overload.
