Abstract
Systems and methods for dynamically updating bit loading profile assignments among a plurality of cable modems.
Claims20
A system comprising a head end in operable communication with a population of cable modems, each of said cable modems using a respective initial subset of bit loading profiles assigned by the head end, each respective initial subset selected from among a set of initial bit loading profiles used by the head end to communicate to the population of cable modems, the head end dynamically updating at least one respective initial subset to an updated subset based on information determined through the use of the set of initial bit loading profiles in the system.
A method for updating bit loading profiles among a plurality of cable modems each communicating with a head end, the method comprising:
- assigning respective first subsets of bit loading profiles to each of the plurality of cable modems, each of the respective first subsets selected from a larger set of bit loading profiles used by the head end;
- and
- using information from the larger set of bit loading profiles to update at least one respective first subset of bit loading profiles.
