摘要： 现有的负载平衡中间件大多采用单一的基于对象的负载平衡粒度，更多地关注同一对象组的不同副本之间的平衡，复杂的分布式应用往往存在多种不同类型的服务对象组共存的情况。该文基于CORBA技术，论述提高负载平衡中间件可扩展性的关键问题、解决方法及其实现，给出了相关的测试结果。

Abstract: Most of the current load balancing middleware adopt the per-object load monitoring granularity, and pay more attention to the balance among the different replicas of the same group. This paper discusses several key problems about how to improve the scalability of the load balancing middleware. Implementations and simulation results are given.

Key words: load balancing, middleware, scalability, complex distributed aplication
