Abstract
A method and system for quality-of-service in a data-over-cable system is provided. A cable modem in a data-over-cable system makes a connection request to a cable modem termination system with a requested quality-of-service. The requested quality-of-service includes class-of-service, quality-of-service and other related parameters. The connection request is sent from a cable modem or a cable modem termination system to a Quality-of-Service ('QoS') server. The OoS server determines if the cable modem termination system has enough bandwidth to make the connection to the cable modem with the requested quality-of-service. If the cable modem termination system has enough bandwidth, a quality-of-service identifier is to returned to the cable modem termination system. The cable modem termination system uses the quality-of-service identifier to make a connection to the cable modem with the requested QoS to the cable modem. The QoS server reduces the computational burden and complexity of software on the cable modem termination system. The QoS server is flexible and adaptable to new QoS parameters and provides a standard way to balance QoS requests among multiple cable modem termination systems.
