The ARPA Advanced Research Projects Agency computer network involves the interconnection of about twenty as of 1971 different research computers across the country by means of a store-and-forward message switching net. The development of such a network is an expensive and complicated undertaking which involves a variety of engineering trade-offs and decisions. Since there has been little prior experience which directly relates to the design of such a network, an extensive measurement and evaluation capability was included in the message switching computers the Interface Message Processors or IMPs. UCLA was designated to be the Network Measurement Center with the responsibility of defining the measurements that were necessary for the support of the analytic and simulation model activities, and to determine the performances of the network by the use of these measurement facilities. The primary concern of this report has been with the development of such a measurement capability and the utilization of this capability to create and iteratively improve analytic models of the network behavior as well as the true system parameters.
