Abstract:
1. In a requesting computer system that is network connectable along with one or more other computer systems to a network, a method for more accurately determining if the network has sufficient available resources to transfer a data stream, the method comprising: an act of broadcasting a start admission control message, the start admission control message signaling to the other computer systems that an active probing experiment is to be conducted; an act of conducting an active probing experiment to identify the available bandwidth of the network, the active probing experiment detecting network load caused by any other data stream and companion data stream being transferred from a transmitting computer system; an act of determining if the network has sufficient available bandwidth to transfer the data stream based on the results of the active probing experiment; and an act of broadcasting an end admission control message, the end admission control message signaling to the other computer systems that the active probing experiment has completed.
