中文摘要：

解决云计算平台可能出现的短时间用户群峰值需求而商家却要为此巨额投入，提出搭建基于移动agent的开放云联盟，考虑到云联盟环境计算任务的安全性和私密性，采用计算任务分段及迁移机制。研究计算任务带权分段并以此进行位置部署，设计实现由分段机制产生的超量子任务段随agent自适应迁移机制，并给出算法实现。实例仿真表明，计算任务分段及迁移机制是有效的，构建的云联盟可以解决云平台可能出现的短时间峰值需求问题。

英文摘要：

To deal with the huge investment for the peak requirements based cloud platform in a short time, building an open cloud computing federation based on mobile agent is proposed. Considering the security of computing tasks in a cloud computing federation environment, a computing task sectioning and moving scheme is adopted. The computing task sectioned based weight is researched. The scheme of a large number of mobile agents moving with subtask sections is designed and implemented, and the algorithm is presented. Finally, simulation with an instance shows that computing task sectioning and moving scheme is valida- ted. The possible problem of the peak requirements in a short time can be solved.
