【摘要】 与传统分布式集群环境迁移进程不同,虚拟计算环境下的迁移实体是虚拟机,文章针对虚拟机粒度较大的特性,提出了一种基于虚拟机迁移的负载均衡算法。该方法用CPU预测技术避免呈下降趋势时发生不必要迁移。文章的算法采用全局平均的负载均衡策略,只有当负载差值大于一定值才触发迁移。更多还原

【Abstract】 Different with migrating process in traditional distributed computing environment,the load balancing in virtual computing environment is realized through migrating virtual machine who’s intensity is high,this paper presents a load balancing algorithm based on the virtual machine migration.The CPU forecast technology avoid a tiny and temporary load peak value triggering unnecessary migration.This paper uses the global average load-balancing strategy,and trigger migration only when the load difference is greater than a certain value.更多还原
