In addition to the CMTS configuration, added to the CM configuration file
are a two parameters that describe how much more bandwidth (peak rate) and
how many more bytes (burst size).  More here on Cisco's implementation:

     Depending on the kind of access gear being used there are different 
methods for making this work.  This kind of technology is most commonly 
deployed on DOCSIS cable systems, for example Comcast has this 
trademarked as PowerBoost and they have done a ton of marketing around 
it.  You can implement this kind of temporary speed boosting for cable 
systems on several CMTS brands (I know Cisco and Arris) and its probably 
possible for any CMTS that is certified for D2 or better.  I haven't 
found a certified modem that couldn't handle that side of things.
