Statistical methods for estimating time and rate parameters of digital communication

Statistical methods are given for estimating time and rate parameters of digital communication systems according to the specifications of proposed federal standards. The methods may be applied to delay, disengagement, transfer and service times, and to transfer rates. Some ARPANET and Bell System data are examined for the form of distribution of times. The properties of various types of estimators are discussed, and the sample mean is recommended. Approximate confidence limits are given for time and rate parameters. A step by step procedure is provided for designing an experiment to estimate time and rate parameters with prescribed accuracy.
