摘要
HLA(high level architecture)提供了数据分发管理机制,为提高系统的可伸缩性提供了可能.介绍了HLA中数据分发管理的过滤原理,研究分析了当前数据分发管理实现中的几种不同方法,改进并优化了一种数据分发管理实现策略--基于层次结构化(hiberarchy-based)的数据过滤机制.分析表明,该方法能大大减少匹配操作的时间,组播地址资源的使用效率也较高,从而减少了不相关数据的传输,节约了系统及网络资源,较好地实现了数据过滤.
HLA(high level architecture) provides the mechanism of data distribution management and the possibility for improving the system scalability. The paper introduces the basic functions of data distribution management in HLA. Several current implementation approaches are studied and analyzed. An optimized solution of DDM implementation, the hiberarchy-based approach, is improved. Analysis indicates that the approach can greatly decrease the matching operational time, and highly improve the efficiency of the use of the multicast address, as a result it reduces the transmission of the irrelevant data, saves the system and network resource, and preferably realizes the data filtration.
