中文摘要：

为了解决分布式文件系统的负载均衡问题，研究了多种负载均衡算法，分析各种算法的优缺点．综合了静态权重轮询算法和动态负载均衡算法两类算法的优点，提出一种自适应的综合动态负载均衡算法，它实现简单、降低了获取反馈信息的开销且不失实时性．经过试验比较，该算法能有效地降低平均响应时间和提高吞吐量，负载的分配更为均衡．

英文摘要：

In order to solve load balancing of the distributed file system, I did some research into the load balancing algorithms, and analyzed the advantages and disadvantages of them. Combining static weighted round robin algorithm and dynamic load balancing algorithm, this paper proposed an adaptive, comprehensive dynamic load balancing. It is simple, low cost and effective. After more tests, I found that the algorithm can effectively reduce the average response time and increase throughput. It is better than static weighted round robin algorithm and dynamic load balancing algorithm.
