US Patent 7701884 Network communications bandwidth control

A method for controlling real time data communications over a packet based network comprises steps of dynamically measuring data packet loss between a receiver and a sender on the network, dynamically measuring data latency between the sender and receiver, and comparing the dynamically measured data packet loss to a loss limit and comparing the dynamically measured data latency to a latency limit. If one or both of the loss limit or the latency limit is exceeded, then the method may include reducing the rate of data transmission from the sender.
