摘　　要：随着基于HLA的分布式仿真实现技术的日益成熟,对于仿真的效率和精确性的要求也越来越高。大规模的分布式仿真中,负载平衡成为影响仿真效率和正确性的关键问题,然而HLA本身并未提供负载平衡机制。在对负载平衡问题和HLA深入研究的基础上,在HLA中实现了负载平衡机制,使用计算机性能的评价参数CPU占有率和内存使用率作为评估标准,以确定进行负载迁移的对象。最后通过实验证明,该机制能有效地平衡仿真系统中各节点之间的负载,从而验证了该机制的有效性。As the implementation technology of the distributed simulation is becoming maturer,the requirements of simulation efficiency and precision are also becoming higher.In the large scale distributed simulation,the performance of load balancing becomes the key problem affecting the efficiency and the correctness of the simulation,however,the HLA standard never referred to this load balancing framework.Based on in-depth study of load balancing problem and HLA standard,embed the load balancing in the HLA,and the evaluation criteria is percentage of CPU and memory utilization which are evaluation parameters of computer.The realization method looks up the object which should be transferred.Finally,an experiment testifies that this mechanism can make a balance among the nodes of the simulation system effectively.Through this way,the new mechanism is a validity method.
