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 includes the steps of: describing a control variable which represents a target flow rate of content from the server device to each client device; determining time-varying constraints on the target flow rate of the content; determining a cost function of the control variables for all clients, wherein the cost function represents an aggregate flow rate and is a sum of all flow rates for all clients; and prescribing bandwidth to all clients based upon a value of the control variables that maximize the cost function comprising performing periodic computations to update the value of the control variable such that the bandwidth can be continuously allocated to each client.

Connection acceptance control

A method for bandwidth allocation for delivery of multimedia data from at least one server to one or more clients over a network. The method includes the steps of: determining a maximum flow rate and a minimum flow rate for each client; determining a flow rate range for each client as given by the difference between the maximum flow rate and the minimum flow rate; sorting the one or more clients according to the flow rate range; initializing a current flow rate for each client as the minimum flow rate and summing the flow rate into total server flow rate; establishing remaining server bandwidth; and allocating the remaining server bandwidth to clients, based upon the sorted client's flow rate ranges.

Method for connection acceptance control and optimal multi-media content delivery over networks

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.

Method for connection acceptance control and rapid determination of optimal multi-media content delivery over networks

A system for allocating bandwidth between a server device and at least one client device. The system includes a call acceptance module operative to receive an incoming request for service; a flow regulator configured to deliver content at a modulated target flow rate, the content being delivered between the server device and a respective client device when a call is accepted by the call acceptance module; and a flow optimizer configured to modulate the target flow rate of the flow regulator in order to optimize an aggregate flow of content.

A method is disclosed for call and/or connection acceptance control and the optimal delivery of multimedia (audio/video) data over networks. This method involves the establishment and monitoring of certain criteria which may be used to maximize the number of simultaneous clients without sacrificing quality-of-service for already-connected clients. Methods are disclosed for maximizing total throughput as well as maximum charge models for different levels of service. The disclosed methods solve these optimization problems by expanding on linear-program techniques in manners geared towards multimedia content delivery over networks and many variations suitable for varying business models are disclosed.

Method for connection acceptance and rapid determination of optimal multi-media content delivery over network

An event dispatching subsystem pre-processes event messages received by an event driven main system having a context consisting of a defined set of major and minor state variables each having a defined range of values. The event dispatching subsystem defines a set of ports, and bands within each port, where each distinct type of event message that can be received is assigned to a respective one of the ports and bands. The messages in each band are stored in a FIFO queue until the messages in the band are processed. Each band has an assigned priority, which imposes a processing priority order on the messages stored in the various bands, and a band status value. An event dispatcher considers one event message at a time, where the event message to be considered is selected in accordance with the priority values of those bands, if any, having a band status value indicating that processing of events messages stored in the band is enabled. The dispatcher selects a disposition for the selected event based on the event's parameter values and the state variable values for the main system. The event dispatcher executes one of a plurality of predefined disposition action procedures, selected in accordance with the selected event disposition, for disposing of each event message. At least one of the disposition action procedures that can be invoked for event messages received by each port sends event messages to the main system for further processing.
