Research on advanced application technology of large-scale internets and Open distributed processing

该项目的研究从1993年到1995年进行了3年。该项目团队由来自多所大学的约45名研究人员组成。研究预算22 600万美元（约20万美元）的大部分用于支付举行会议和研讨会的旅费。本项目购买的硬件几乎只有13块工作站和个人电脑的isdn板和3块工作站的atm板。由于这个项目的结果，在许多大学，包括那些拥有大型计算机中心的大学，ISDN连接已经成为与互联网的临时或廉价的连接。当我们在1992年制定计划时，这种使用ISDN线路的模式在世界上任何地方都是罕见的，但ISDN的使用正在日本公司中普及。我们的项目似乎对这种传播产生了影响。该项目取得的主要成果在另一份报告中提出。在研究/开发问题和实际问题上取得的主要成果如下：通过综合业务数字网（ISDN）线路和广域互联网，通过移动骨网实现的视频/音频电话会议系统。具有根据线路速度和拥塞动态变化的图像分辨率和帧率的多媒体通信系统。研究通过WWW服务器进行信息交换。利用156Mbps ATM交换机和线路实现ip over ATM的研究5。广域网络运维方法的改进如何在小学/初中/高中教育中使用互联网

The research in this project was carried out in 3 years from 1993 through 1995. The project team consisted of about 45 researchers from many universities. The most portion of the research budget of \22,600,000 (about US$ 200,000) was spent for travel grants in holding conferences and seminars. The almost only hardware purchased by this project includes 13 ISDN-boards for workstations and PCs, and 3 ATM-boards for workstations. AS a result of this project, ISDN connection has become available for temporary or inexpensive link to the internet in many universities including those with large-scale computer centers. While this mode of use of ISDN lines was rare anywhere in the world when we made the plans in 1992, the use of ISDN is spreading in Japanese companies. Our project seems to have had impacts on this diffusion.The main results achieved by the project are presented in a separate report. The major achievements in research/development issues and practical issues are as follows.1. A video/audio teleconference system via M-bone internet by way of ISDN lines and wide-area internet.2. Multimedia communication system with dynamically-changeable image-resolution and frame-rate in accordance with line-speeds and congestion3. Research information interchange through WWW serers4. Research on IP-over-ATM by the use of 156Mbps ATM switches and lines5. Improved methods of wide-area internet operation and maintenance6. How to use the internet n elementary/middle/high-school education
