In the schemes considered, precedence is determined moment-by-moment, automatically for all traffic in the network. Precedence is computed as a composite function of: (1) the ability of the network to accept additional traffic; (2) the “importance” of each user and the “utility” of his traffic; (3) the data rate of each input transmission medium or the transducer used; and (4) the tolerable delay time for delivery of the traffic.
