摘　　要：底层通信方式是影响HLA/RTI仿真系统性能的一个重要因素。采用组播的通信方式能够显著的提高HLA/RTI仿真系统的性能。基于IP组播的应用研究了很长时间,但在实施上还存在很多困难,软硬件方面的问题都有。近年来,不少人都开始反思IP组播体系结构本身的问题,并提出将复杂的组播功能放在端系统来实现的新思想,这就是应用层组播技术。该文根据应用层组播的思想,设计实现了一套简单的基于应用层组播的HLA/RTI组播通信解决方案,为解决HLA/RTI仿真系统的通信问题提供了新思路。The way of communication has much effect on the performance of HLA/RTI simulation system. Using multicasting instead of broadcasting in HLA/RTI simulation system can improve the performance greatly. Much time had been taken to study IP multicasting, however, it's difficult to put it into application. Recently, a new thought was put forward by some researcher. The new technology is called application layer multicast which implement the multicasting in end system instead of in network system. This paper proposed a solution to the HLA/RTI communication based on the application layer multicast.
