Method and system for selecting from a plurality of configuration profile records for channel bonding operation

摘要

In DOCSIS 3.0 a greater level of configuration is possible for cable modems than was available in earlier versions. The CMTS potentially receives many possible configurations from a new CM. The standard does not indicate how the CMTS should configure a CM that can support more than one possible configuration. A CMTS' operator specifies preferences for certain channel configurations. The CMTS evaluates the configuration profiles received from a booting CM and determines the best profile to attempt to accommodate based on the specified preferences. The CMTS determines how to instruct the CM to configure itself based on the available channel resources than can accommodate the selected configuration profile.

1. A method for determining channels to use in channel bonding communication with a cable modem, comprising:
specifying preferences for certain parameters of cable modem channel assignment over other parameters; receiving a plurality of profiles from a booting cable modem that each indicate a different channel bonding arrangement; selecting one of the plurality of profiles based on the specified preferences for certain parameters of other parameters; assigning channels for communication with the booting cable modem based on the selected profile; and transmitting a message containing an instruction to the cable modem representing instructing it how to tune its circuitry based on the assigned channels.
