Abstract
A method and system for initializing cable modems with dynamic protocol servers is provided. The method and system allow a dynamic protocol server such as a dynamic Trivial File Transfer Protocol ("TFTP") server to override a request for a standard configuration file whose name is supplied to a cable modem in a Dynamic Host Configuration Protocol ("DHCP") response message during initialization. Instead, the dynamic TFTP server identifies a cable modem by performing a reverse Domain Name System lookup of an Internet Protocol address used for the cable modem. Based on the determined identity for the cable modem, the dynamic TFTP server constructs a new configuration file specifically for the cable modem and transfers it to the cable modem. The new configuration file is different from the default configuration file originally requested by the cable modem. Creating a new configuration file with a dynamic protocol server allows greater flexibility for configuring cable modems in a data-over-cable system.
