<P>PROBLEM TO BE SOLVED: To control admission of data streams to a network. <P>SOLUTION: Appropriate determinations in a series of tests, which transit from more passive tests to more active tests, control the admission of data streams onto a network data path. The more passive tests can include a promiscuous mode and packet-pair tests. When the results of more passive tests indicate a reduce likelihood of a data stream causing a network data path to transition into a congested state, the network data path can be actively probed to make a more precise determination on the likelihood of congestion. A train of diagnostic data packets is transmitted at a diagnostic data transfer rate having a significantly reduced chance of causing congestion. A train of target data packets is transmitted at a requested application transfer data rate. The number of target data packets received within a specified delay threshold is compared to the number of diagnostic data packets received with the delay threshold. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
