Local, regional and large scale integrated networks. Volume 3. Recent advances in large scale integrated networks

The large network research conducted by Network Analysis Corporation under contract with the Advanced Research Projects Agency had the following objectives: To define delay and reliability performance criteria for large network design. To identify adequate network structures for large, distributed requirements. To investigate the impact of system parameters and characteristics (e.g., hardware cost, line cost, traffic volume etc.) on large network design and performance. To determine the impact of satellite carriers on large network design. To determine the impact of precedence and priority procedures on network design and performance in a large network environment, with a wide variety of traffic types and delay requirements. An integrated, multilevel network architecture was shown to be the most cost-effective solution for large, distributed requirements. The multilevel architecture offers the best trade-off between line costs, switch costs and delay and reliability performance. Furthermore, it shows excellent controllability and growth flexibility properties.
