Studies on Construction Method of Operating System Based on Mobile Agents

在本研究中，我们研究了一种新的适应环境和系统配置变化的操作系统构建方法。在本研究中，我们首先提出了一种对处理器、内存、外围设备等计算机资源进行抽象的方法。接下来，我们开发了一种实现将每个对象作为代理进行管理的功能的方法。在此基础上，研究了智能体的动态创建、更新和迁移机制。此外，我们还研究了由代理对各种计算机资源进行位置透明管理的方法。1.计算机资源的抽象方法：提出了将通过网络连接的每一个计算机资源抽象为一个对象的方法。具体来说，对象分为两类：物理对象和数据对象。物理对象用于抽象计算机资源，数据对象是系统中使用的数据结构。2.代理的执行环境：研究了代理的自主性和移动性机制，并开发了基于反射的自主机制。3.代理对计算机资源的管理方法：我们开发了代理在计算机之间迁移的机制，并对计算机资源进行位置透明的管理。4.代理之间的通信方法：我们开发了位置透明的通信方法，用于通过代理的协作来管理计算机资源。5.负载分配的资源管理：为了有效地分配计算机资源，我们提出了负载分配和负载均衡的方法。

In this research, we have investigated a new construction method of Operating system that is adaptable to changes of environment and system configuration. Firstly in this research, we have developed an abstraction method of computer resources such as processor, memory, peripheral devices and so on. Next, we have developed a method for implementing the function for managing each object as an agent. Based on these methods, we have investigated the mechanism of dynamic creationlupdate of agents and agent migration. Furthermore, we have investigated the method for managing various computer resources location-transparently by agents. The result in this research is as follows.1.Abstraction method of computer resources: We have developed the method for abstracting each computer resource connected via the network as an object. Concretely, objects are categorized into two kinds of objects : physical objects and data objects. Physical objects are used for abstracting computer resources, and data objects are data structures used in the system.2.Execution environment for agents : We have investigated the mechanism for the autonomy and mobility of agents, and developed the autonomous mechanism based on the reflection.3.Management method of computer resources by agents : We have developed the mechanism which agents migrate between computers and manage the computer resources location-transparently.4.Communication method between agents : We have developed the location-transparent communication method for managing the computer resources by agent co-operations.5.Resource management with load distribution : In order to efficient distribution of computer resources, we have developed the load distribution and load balancing method.
