项目摘要

The purpose of this research is to show how to plan the future inter-university network in Japan which will be nessesary infrastructure for research activities. The seven inter-university computing centers and NCSIS(National Center for Science Information System) should play a very important role in various fields. We have examined thoroughly the planning of a large scale network system which can be viewed as consistng of some wide-area networks and a large number of local-area networks. The following subject were discussed: (1) Applications of satellite communications (2) Hierachical architecture of its large scale network (3) Interconnection of the science information network in Japan and them in different countries (4) A study on communication models by a knowlege engineering method (5) A design of knowlege-based systems using conputer networks.As a result of deliberate investigations,we have obteined the following valuable informations: (1)The expected network system should provide high-speed transmission facilities,and functions to access efficiently various information and network services extending to a much large geographical area (2)It is very important to design its network after due considaration of communication technologies, its applications and its manegiment of the futhure. (3)The combination of voice,data,still image and video in the same network is essential to develop rapidly artifficial interlligence technologies.

本研究的目的是展示如何规划日本未来的大学间网络，这将是研究活动的必要基础设施。七个校际计算中心和NCSIS（国家科学信息系统中心）应该在各个领域发挥非常重要的作用。我们深入研究了一个大型网络系统的规划问题，这个系统可以看作是由一些广域网和大量的局域网组成的。本文主要讨论了以下几个问题：(1)卫星通信的应用；(2)卫星通信大规模网络的层次结构；(3)日本科学信息网络与国外科学信息网络的互联互通；(4)基于知识工程方法的通信模型研究；(5)基于计算机网络的知识系统设计。经过深思熟虑的研究，我们得到了以下有价值的信息：(1)预期的网络系统应提供高速传输设施，并能有效地访问扩展到更大地理区域的各种信息和网络服务；(2)在设计网络时充分考虑未来的通信技术、应用和管理是非常重要的。(3)语音、数据、静止图像和视频在同一网络中的结合是快速发展人工智能技术的必要条件。
