Method and device for measuring the proportion of an ATM cell stream satisfying a determined criterion

摘要

A process and device for measuring the proportion of ATM cells satisfying a criterion. The process includes allocating a first numerical value to the cells passing through a specified point of an ATM network for satisfying criterion and allocating a second numerical value to the cells which do not satisfy the criterion. An exponential mean is then performed of the string of values thus allocated to each cell.
