摘　　要：针对FTP服务器集群全局平衡性差的问题,该文提出一种负载平衡方案。该方案包括分布式统一平台的构建和FTP负载平衡策略的选择。基于JXTA技术构建分布式统一平台,设计全局-局部-再全局的自适应负载平衡策略对FTP请求进行动态调度,将集群划分成多个互不相交的子集,每个子集有一个超级节点,子集间的协商通过超级节点间的相互通信完成。实验证明了该方案的有效性。To solve problem of the FTP server-cluster＇s global balance, this paper proposes a novel load balancing scheme, including the choice of FTP load balancing strategies and the construction of the uniform distributed platform implemented by JXTA. It adopts the adaptive FTP load balancing strategy, called global-local-secondary global, to schedule the download requests of clients dynamically. The cluster is divided into several subsets disjointed mutually, and each subset has only one super node. The negotiation among subsets is implemented by communication of super nodes. The validity of the scheme is testified by experiments.
