基于市场机制的移动Agent系统资源管理

Market-based resource control for mobile Agents

分析了移动Agent的运行机制:移动Agent运行时要消耗所在主机的计算机资源,恶意的移动Agent可以通过大量占用主机资源,引发服务拒绝攻击,因此主机资源的管理是移动Agent系统设计的重要环节。讨论了使用货币的基于市场机制的资源管理策略及主机资源的静态和动态定价策略,同时对实现进行了分析。

Mobile Agents are programs that can migrate from machine to machine in a heterogeneous network. As mobile Agents move across a network,they consume resources. Not only is there the additional congestion incurred through normal mobile Agent use,but there are additional risks from denial-of-service attacks and other irresponsible uses of resources. The problem is remedied by inposing an ecnomic market on mobile-Agent systems where Agents purchase resources from host sites. Fixed-pricing and dynamic-pricing polcies for resources are discussed. The implementation of market-based resource control is also analyzed.
