| 1. A method for providing network access to a shared access communications medium for a plurality of users, the method comprising
the steps of:
conducting lookahead scheduling for use in making user channel assignments by forecasting schedule transmission opportunities
on one or more channels of the shared medium;
conducting predictive admission control by arbitrating user requests for access to the shared medium based on predicted aggregate
demands, wherein the step of conducting predictive admission control based on predicted aggregate demands comprises the steps
of:
receiving a request for a service flow from a communication device;
comparing the demands of the request to the anticipated resources of the channel;
based on the comparing step, determining whether the request is to be granted or whether the request is to be modified; and
based on the step of determining whether to grant or modify the request, modifying the service flow of one or more communication
devices to allow connectivity; and
balancing load by making channel assignments such that a plurality of users are each assigned a respective channel of the
shared medium based upon a predicted need.
