Abstract
A method and system for quality-of-service in a data-over-cable system using configuration protocol messaging is provided. The method and system include determining whether a cable modem termination system has enough available bandwidth to provide a quality-of-service connection requested by a cable modem from a quality-of-service server. The quality-of-service server uses Dynamic Host Configuration Protocol ('DHCP') messaging to send and receive quality-of-service identifiers indicating that the cable modem termination system has enough available bandwidth to provide a quality-of-service connection requested by a cable modem. The cable modem termination system creates a quality-of-service connection to a cable modem based on the quality-of-service identifiers returned from the quality-of-service server. The quality-of-service server using DHCP messaging provides a standard and efficient process to reserve bandwidth for quality-of-service connections in a data-over-cable system. The quality-of-service server is also used to distribute quality-of-service connection requests from cable modems among multiple cable modem termination system in a data-over-cable system.
