基于HLA分布式仿真中的负载平衡技术研究

The Research of Load Balance Technology in Distributed Simulation Based on HLA

HLA为实现分布式仿真的互操作和重用提供了一个通用的技术框架,但HLA中并未提供负载平衡机制。通过对HLA/RTI及负载平衡技术的研究,在HLA中实现了负载平衡机制,同时通过在系统中加入结点检测模块的方法解决了实体迁移过程中出现的问题。与没有采用负载平衡机制的系统相比,采用该机制的系统性能明显提高,具有较高的实用价值。

HLA provides a universal technology frame for realizing the interoperability and reuse of distributed simulation. But HLA doesn＇ t provide load balance mechanism .Through the research of HLA/RTI and load balance technology ,this paper realizes load balance mechanism in HLA ,proposes to add node detector in the system to solve the problem which is in the process of entity migration. Compare with the system that does not adopt the load balance mechanism, the system performance improves obviously, it has high practical value.
