Abstract:
1. A method for allocating the available upstream bandwidth, BW, among service categories within a point to multi-point communications network, comprising the steps of: allocating a nominal upstream bandwidth amount, BW allocating an excess subscription factor, P measuring the actual upstream bandwidth demand at a time t, D initially setting a first set of effective upstream bandwidth amounts, E determining whether there is excess upstream bandwidth, C(t), to be distributed among said plurality of service categories within the network utilizing the equation said determination being positive when C(t)>0; and distributing, when said excess upstream bandwidth determination step is positive, said excess upstream bandwidth, C(t), among said first set of effective upstream bandwidth amounts, E wherein the function ƒ is a min-max weighted fairness scheme utilizing said nominal upstream bandwidth amounts BW wherein α a is a number less than or equal to 1 and represents a relative importance between BW i , and P i .
