Abstract
A technique for ensuring independence of random samples of input queues of time-shared processing systems taken during a fixed interval to determine system usage involves interposing guardband intervals of minimum time duration between such samples. A stratified sampling method is disclosed which develops successive stratum or subintervals, positions a data sampling at a random point in each subinterval and interposes a guardband interval between successive subintervals. A simple random sampling method is disclosed which takes a sampling at the termination of a random subinterval and interposes a guardband interval between successive random subintervals.
