摘　　要：描述了一种在集群中异构节点之间的应用程序进行动态结合的中间件。它通过将应用对象平均分配到系统中节点来均衡集群中的负 载。同时描述了促进对象迁移与决策组成的该中间件的体系结构,以及将一个对象从一个节点迁移到另一个节点的通信协议。最后介绍了用 Java和Jini实现该中间件的技术。This paper describes a middleware that enables its applications to dynamically incorporate heterogeneous nodes of a cluster. It distributes the objects of the application across the nodes with the objective to evenly distribute system load. It describes the architecture of the middleware that facilitates object migration and its decision making components. It contains a negotiation protocol to facilitate migration of objects from one node to another. Finally, It describes an implementation of this middleware using Java and Sun's Jini framework.
