ONLINE CONFIGURATION METHOD, SYSTEM, AND APPARATUS FOR CABLE MODEM

摘要

The present invention relates to the technical field of communications, and in particular, to an online configuration method, system, and apparatus for a cable modem. The method comprises: a CM sends a DHCP request message to a DHCP server, and receives a DHCP response message fed back by the DHCP server, the DHCP response message carrying at least one file identifier for uniquely identifying a configuration file requested by the CM; and the CM compares the file identifier carried in the DHCP response message with file identifiers corresponding to locally saved configuration files, and when it is determined that an identical file identifier exists, completes configuration by using a locally saved configuration file. Therefore, a TFTP request configuration procedure is omitted, network traffic and system resource consumption are greatly reduced, and service recovery time is shortened.
