层次式多联盟结构框架及其时间管理服务的研究

随着仿真技术的发展，人们对大规模分布式仿真的应用需求越来越迫切。为了解决单联盟集中式RTI仿真规模受限的问题，AnthonyCramp等人提出了层次式多联盟的联盟集合的思想，并对分布式盟员代理(Distributed Federate Proxy DFP)结构的时间管理进行了简要描述，其描述是基于美国国防部HLA 1．3版本的；该文主要介绍了层次式多联盟的基本结构及主要数据流程，并重点给出了符合IEEE1516标准的层次式多联盟的时间管理算法，对分布式盟员代理部件(Distributed Federate Proxy Components DFPC)和仿真节点SN的最大可用逻辑时间(Greatest Available Logical Time GALT)的计算及其逻辑时间的推进过程进行了较为详尽的分析。

Research on Architecture of Hierarchical Multi- Federation and Its Time Management Service

With the development of simulation technology, it is more and more exigent that people apply large scale distributed simulation. To solve the problem that the scale of simulation is restricted in the centralized RTI-server of unique federation, the notion of hierarchical federations community was introduced, and time management of Distributed Federate Proxy (DFP) structure was presented simply by Anthony Cramp and so on (the statements comply with DMSO HLA1.3). The basic architecture of hierarchical multi-federation and its data flow are presented primarily in the paper. It is emphasized that the algorithm of time management of this architecture based on IEEE1516, the calculation of GALT and logical time advance process which are associated with components(DFPC) and Simulate Node (SN) are analyzed in relative detail.
