The National Biomedical Communications Network has evolved both from a set of conceptual recommendations over the last twelve years and an accumulation of needs manifesting themselves in the requests of members of the medical community. With a short history of three years this network and its developing structure have exhibited most of the stresses of technology interfacing with customer groups, and of a structure attempting to build itself upon many existing fragmentary unconnected segments of a potentially viable resourcesharing capability. In addition to addressing these topics, the paper treats a design appropriate to any network devoted to information transfer in a special interest user community. It discusses fundamentals of network design, highlighting that network structure most appropriate to a national information network. Examples are given of cost analyses of information services and certain conjectures are offered concerning the roles of national networks.
国家生物医学通信网络是在过去十二年里从一系列概念性建议以及医疗界成员的需求积累中发展而来的。这个网络虽然只有三年的短暂历史，但其发展结构已经展现出了技术与客户群体对接时的大部分压力，以及一个试图在潜在可行的资源共享能力的许多现有零散、无关联部分基础上构建自身的结构所面临的压力。除了探讨这些主题，本文还探讨了适用于任何致力于在特定兴趣用户群体中进行信息传输的网络的设计。它讨论了网络设计的基本原理，突出了最适合国家信息网络的网络结构。文中给出了信息服务成本分析的例子，并对国家网络的作用提出了一些推测。
