TL;DR: Algorithms for predicting end-to-end performance measurements in private networks are described based on point- to-point traffic data and a network routing guide and incorporated in the Enhanced Network Administration System.
Abstract: This paper describes algorithms for predicting end-to-end performance measurements in private networks. Service characteristics such as end-to-end blocking and delay are calculated based on point-to-point traffic data and a network routing guide. These techniques have been incorporated in the Enhanced Network Administration System. The system is routinely used by AT&T Long Lines and operating company network administrators for private network design and evaluation.

TL;DR: A network protocol layer is presented which is used to provide a homogeneous operating environment and to ensure the availability of network resources and to generalize properties of diverse local networks which can be measured.
Abstract: Diverse network application requirements bring about local networks of various size, degree of complexity and architecture. The purpose of this paper is to present a network protocol layer which is used to provide a homogeneous operating environment and to ensure the availability of network resources. The network layer process probes the underlying local network to discover its properties and then adapts to changing network conditions. The principle contribution of this paper is to generalize properties of diverse local networks which can be measured. This is important when considering maintenance and service of various communication links. Three type of links are point-to-point links, multi-drop, loop or switched links and multi-access contention data buses. A prototype network is used to show a complexity improvement in the number of measurement probes required using a multi-access contention bus. Examples of measurement techniques and network adaption are presented.
