Construction of autonomous distributed system for large capacity content dellivery

移动代理系统是由移动代理程序构成的系统。移动代理通过在服务器计算机之间迁移来执行某些数据处理。在本研究中，我们提出了一种称为“现金”的快速迁移技术。通过使用现金技术，代理程序及其数据不应该每次迁移都转移。只传输一次就足够了，我们提出的技术支持更快的代理迁移。本文还讨论了代理系统的备份方法和基于计算机执行能力的系统配置方法。通过实验验证了所提方法的有效性。

Mobile agent system is a system which is constructed with programs called as mobile agent. Mobile agents execute certain data processing with migrating among server computers. In this research, we propose fast migration technique called "cash". By using cash technique, agents programs and their data should not transfer each migration. Only one transfer of them is enough and our proposed technique enabled faster agent migrations. In this research, back up method of agent systems and system configuration method according to computer execution abilities are also discussed. Effectiveness of proposed methods are confirmed by several experiments.
