Method and apparatus for evaluating QOS in ATM multiplexing apparatus in which priority control is performed and for controlling call admissions and optimizing priority control on the basis of the evaluation

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