Computer communication network design: Experience with theory and practice

Abstract

The design of the ARPA Computer Network brought together many individuals with diverse backgrounds and philosophies. In this paper, we review the methods used in the design of the Network from the vantage of over two years' experience in its development. The design variables, system constraints, and performance criteria for the network are discussed along with an evaluation of the tools used to design an efficient and reliable system. The design procedures and the conclusions reached about the network's properties appear to be generally applicable to message switched networks. Consequently, the results of this paper should be useful in the design and study of other store‐and‐forward computer communication networks.
