ABSTRACT:
A method for establishing class of service configuration in a network device of a broadband cable network using Dynamic Host Configuration Protocol (DHCP) is disclosed. A request to obtain a network address presented using DHCP is received from a network interface unit over the cable network, generally upon boot up of the network interface unit. A DHCP message is received from a registration center, and the message includes a network address and a quality of service code value associated with the network interface unit. Based on the quality of service code value, a quality of service configuration is established in the cable network for the network interface unit. As a result, quality of service information is obtained for each network interface unit in the network, specifically when the network interface unit is activated, and as part of its boot-up sequence. Carrying the quality of service information in a DHCP message enables configuration of the network rapidly and without introducing an additional protocol.
