ABSTRACT:
A group poll mechanism (GPM) that schedules upstream bandwidth for cable modems by pointing a request opportunity normally reserved for a single service flow to more than one service flow. Essentially, instead of using the seldom-used poll requests one per service flow, this same request opportunity is pointed to multiple service flows. In such kind of a scheme the GPM gives the same mini-slot to multiple service flows. The GPM implements the use of place-holder SIDs and novel mapping of information elements in MAP messages.
