Abstract: This paper describes a measurement center for the NBSNET, a distributed, broadcast local area computer network (LAN) at the National Bureau of Standards. A LAN measurement center allows careful testing and evaluation of a network under normal and varying user-defined conditions. The measurement center consists of three components: an artificial traffic generator, a monitoring system, and data analysis software. The traffic generator emulates varied loads on the network, allowing for controlled experimentation and functional testing. The monitoring system captures measurement information about both artificial and normal network traffic. Analysis software summarizes this information into ten measurement reports following each monitoring period. Implementation issues and problems are discussed.

TL;DR: These particular network technologies are only applicable over a limited geographical area, say within a radius of a few kilometers and because of this are now usually referred to as ‘Local Area Networks’.
Abstract: During the past few years a number of potentially cheap and reliable network technologies have been developed which provide high speed, low error rate packet-switched communication on a distributed basis. In these technologies the communications channel is a single cable running round an area with host computers connected to the cable by ‘T-junctions’ (see fig. 1). Addressed packets are sent on the cable to allow all-to-all communication between the hosts and use of the channel is divided among the hosts that wish to transmit by some time-division scheme. Two well-known examples of this type of network are the Xerox ‘Ethernet’ (ref 1) and the ‘Cambridge Ring’ (ref 2). These particular network technologies are only applicable over a limited geographical area, say within a radius of a few kilometers and because of this are now usually referred to as ‘Local Area Networks’.

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.
