项目摘要

The aim of this research was to study the possibilities of the real time instruction system which enables real-time sharing voices, images and operations of applications among a large number of users at remote places, and to attempt to develop the system.There were already "Application Level Multicast (ALM)" systems. However, there was no system which enables the bi-directional exchanging of information between a large number of hosts and which synchronizes the information. Our research is a study which advances the study of current ALM.In the three year term of this research, we did the followings1. Study the technique of sending a large size of data such like a voice, a movie and a picture to a large number of nodes in short time on a structured P2P system. We also realize the technique.2. Study a mutual exclusion technique for a large number of nodes on a structured P2P system. This mutual exclusion is used to synchronize a large number of nodes. We also realize the technique.We also have developed a real time instruction system which enables real time sharing voices, images and operations of applications among a large number of users at remote places.We also have found out the optimal data partitioning way which reduces the transmitting time of the data.This system also can be used as an industrial machine controller. A complex machine usually has many motors and sensors. It is hard to control the machine by only one computer. The system can control machines like this by connecting a large number of nodes.

本研究的目的是研究实时教学系统的可能性，该系统能够在远程位置的大量用户之间实时共享语音、图像和应用程序的操作，并尝试开发该系统。已经有“应用程序级多播（ALM）”系统。然而，还没有能够在大量主机之间双向交换信息并同步信息的系统。我们的研究是对当前ALM研究的推进。在本研究的三年期限内，我们做了以下工作：研究在结构化P2P系统上在短时间内向大量节点发送语音、电影、图片等大量数据的技术。我们也实现了该技术。2．研究结构化 P2P 系统上大量节点的互斥技术。这种互斥用于同步大量节点。我们也实现了这项技术。我们还开发了一个实时指令系统，可以在远程位置的大量用户之间实时共享语音、图像和应用程序的操作。我们还找到了最佳的数据分区方式，减少了数据的传输时间。该系统还可以用作工业机器控制器。复杂的机器通常有许多电机和传感器。仅用一台计算机很难控制机器。该系统可以通过连接大量节点来控制这样的机器。
