Abstract
A method of bandwidth allocation for delivery of stored digital content from at least one server device to at least one client device by way of a network is disclosed. The method begins by prescribing a control variable which represents a target flow rate from the server device to each client device. Next, time-varying constraints on the flow rate of the content are determined. A cost function of the control variable for each client is determined. The cost function corresponds to a maximized value of the control variable. Finally, bandwidth is prescribed to each client based upon the value of the control variable maximized by the cost function. In this respect, the method achieves optimal allocation of bandwidth between the server and the respective clients.

39. A method of bandwidth allocation for delivery of stored digital content from at least one server device to at least one client device by way of a network, the method comprising the steps of:
-
prescribing a control variable which represents a target flow rate from the server device to each client device;
prescribing a maximum allowed flow rate from the server device to each client device wherein the maximum allowed flow rate is a minimum of a client flow rate ceiling;
determining time-varying constraints on the flow rate of the content;
determining a cost function of the control variables for all clients; and
prescribing bandwidth to all clients based upon the value of the control variables that maximize the cost function. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46)
