摘　　要：传统的基于状态的元数据服务系统负载均衡策略通常采用目录迁移策略来达到均衡的目的,然而这种策略易使系统进入新的不均衡状态而产生"抖动"现象。提出一种将目录迁移与目录复制相结合的元数据服务系统动态负载均衡策略,有效解决了传统的单一利用目录迁移来进行负载均衡容易造成"抖动"的缺陷,提高了系统的效率和稳定性。Traditional load balancing strategy of state-based meta-data service system usually uses directory migration strategy to achieve the object of a balanced state.But this strategy makes the system easy to produce jitter rising from a new unbalanced state.This paper presents a dynamic load balancing strategy for meta-data service system,it combines the directory migration and directory replication and effectively solves the defect of traditional way in likely causing jitter due to only using directory migration for load balancing,and therefore improves the efficiency and stability of the system.
