摘要
借鉴蚁群算法的思想,提出了一种面向负载均衡的自主式虚拟机动态迁移框架,该框架不需要中央管理模块,能够实现服务器的自主迁移,避免了单点失效。利用智能蚂蚁的搜索,实现了自主式框架的迁移机制,而且使用模糊逻辑推理,根据系统的负载状况自动地调整智能蚂蚁的搜索半径来提高搜索性能。最后扩展了云计算平台CloudSim,实现了提出的虚拟机自主式迁移框架。在扩展后的CloudSim平台上进行的仿真实验验证了该框架的可行性。确定了合适的框架参数,并且通过仿真实验与比较分析,验证了所提出的自主式虚拟机迁移框架具有良好的负载均衡效果。
This paper proposed an autonomous dynamic virtual machine migration framework for load balancing based on the idea of ant colony algorithm.The framework does not need central management module so that servers can achieve autonomous virtual machines migration,avoiding the single point of failure.The migration mechanism of the framework is achieved making use of intelligent ants and the ants＇ searching radius can be adjusted automatically according to the load of the system using fuzzy logic reasoning in order to improve the searching performance.At last,this paper extended the cloud computing simulative platform CloudSim to achieve the autonomous virtual machine migration framework proposed in this paper.Experiments were carried out in the extended platform to verify the feasibility of this framework.The parameter of framework was setted,and the excellent load banlancing ability of this framework was demonstrated by analyzing and comparing the results of simulation.
