Systems and methods for determining bit loading profiles for cable modems

A system for determining bit loading profiles for a plurality of cable modems (CMS), the system comprising one or more processors configured to:

• identify a set of bit loading profiles and respective target bit rates of the plurality of CMs, wherein a target bit rate of a CM is determined using a service level of the CM;
• receive respective average bit rates from the plurality of CMs, wherein an average bit rate of a CM is an average net bit rate per subcarrier of the CM;
• determine, using the set of bit loading profiles and the respective average bit rates of the plurality of CMs, a plurality of sets of CMs;
• determine, using the plurality of sets of CMs, one or more bit loading profiles for corresponding CMs of the plurality of CMs;
• and
• send the one or more bit loading profiles to the corresponding CMs.

A method for determining bit loading profiles for a plurality of cable modems (CMs), the method comprising:

• identifying, by one or more processors, a set of bit loading profiles and respective target bit rates of the plurality of CMs, wherein a target bit rate of a CM is determined using a service level of the CM;
• determining, by the one or more processors, respective average bit rates of the plurality of CMs, wherein an average bit rate of a CM is an average net bit rate per subcarrier of the CM;
• determining, by the one or more processors, using the set of bit loading profiles and the respective average bit rates of the plurality of CMs, a plurality of sets of CMs having a first order of sets;
• and
• for each set of CMs in the first order,
• determining, by the one or more processors, based at least on respective target bit rates of the CMs in the set, a plurality of subsets of CMs having a second order of subsets, and
• for each subset in the second order, determining, by the one or more processors, from among the set of bit loading profiles, one or more bit loading profiles for corresponding CMs in the subset.
