Since the days Internet traffic proliferated, measurement, monitoring and analysis of network traffic have been critical to not only the basic understanding of large networks, but also to seek improvements in resource management, traffic engineering and security. At the current times traffic in wireless local and wide area networks are facing…

An outline is presented for a digital computer simulation model for an information network for the State of California. The methodology of simulation is discussed initially. The problems presented by the very large size of the system, in terms of materials, users, communication connections are depicted, and solutions are suggested which permit…

MINDS (Multiple Intelligent Node Document Servers) is a distributed system of knowledge-based query engines for efficiently retrieving multimedia documents in an office environment of distributed workstations. By learning document distribution patterns and user interests and preferences during system usage, it customizes document retrievals for…

Different aspects of human-machine interaction are discussed in the five brief papers that comprise this report. The first paper, "Some Observations on Mental Models," discusses the role of a person's mental model in the interaction with systems. The second paper, "A Psychologist Views Human Processing: Human Errors and Other…

The Network Measurement System (NMS) represents the implementation of a new approach to the performance measurement and evaluation of computer network systems and services. By focusing on the service delivered to network customers at their terminals, rather than on the internal mechanics of network operation, measurements can be obtained which are…

Virtual worlds technology (VWT) uses special computer hardware and software to link humans with computers in natural ways. A data model, or virtual world, is created and presented as a three-dimensional world of sights and sounds. The participant manipulates apparent objects in the world, and in so doing, alters the data model. VWT will become…
