Abstract
The present invention, generally speaking, provides for transmission and flow control of real-time data streams over computer networks. A real-time data stream is transmitted in data packets from a data source in accordance with a predetermined protocol over a shared network, for example. Data packets of said real-time data stream are received at a data destination connected to the local area network. The data destination determines a suggested data rate for the data source based in part on a number of data packets lost during a preceding interval of time and transmits the suggested data rate to the data source. The suggested data rate is received at the data source, which adjusts its data rate of the in accordance with the suggested data rate. The rate adjustment mechanism is designed such that a network segment will not be overloaded with a single isochronous data stream connection and that a disproportionate shared of the network bandwidth is not consumed by the isochronous data stream connection.
