Abstract
A probability transition matrix S.sub.t is formulated that expresses a multiplexing process which includes nested threshold priority control and classified priority control. A state equation using the matrix S.sub.t is solved by substituting therein upper and lower bounds of a probability distribution of a cell arrival count a.sub.t in an average time series, to calculate a probability distribution of a cell length in a buffer. From the thus calculated cell length probability distribution, the QOS is evaluated on a priority class basis. Based on the QOS evaluation, optimization of call admission control and priority control is accomplished.
