移动Agent的资源申请与分配策略模型

The Modal of the Resource Requesting and Assigned of the Mobile Agent

随着移动Agent技术的发展,用户可以根据需要中断某个正在运行的程序,然后将相关的数据或控制信息打成包,通过网络传送到另一台计算机,并从断点处开始执行,当执行完毕后,将最终结果返回到源结点。显然,现实的原因导致目标主机的主人不可能允许移动程序无限制在使用自己的主机资源。文章将根据现有的情况讨论如何构造满足移动程序与主机要求的资源申请与分配模型,通过设计调度树的方法,在主机的资源使用限制与用户程序的服务质量间取得平衡。在文章的最后,讨论了与移动Agent相关的其它问题,并就下一步的研究提出了方向。

With the development of the Mobile Agent technolo-gy ,many programs can pause their running in the first computer,packet the data and the control information to a message,transfer the message to the other comp uter and re-run the programs from the interrupt point.It is impossible that the programs can use the resource of the host freely.In this paper,a new sche duling modal was put forward.A scheduling tree was constructed before the mobi le programs were scheduled.By the way,both mobile pro-grams and hosts can specify constraints on how CPU should be allocated.In the last paragraph,the f uture work was discussed.
