HLA/RTI中分布资源的存取机制研究

Research on Storage and Accessing of Distributed Resource in HLA/RTI

HLA(HighLevelArchitecture)作为分布交互仿真领域最新的技术规范,促进了不同领域、不同类型仿真应用的互操作与可重用,RTI(RunTimeInfrastructure)是HLA的软件实现,其运行效率直接影响仿真应用的整体性能。我们对RTI中涉及的数据资源进行了定义,探讨了资源管理所面临的问题,设计出高效存储、快速索引这些资源的存储方案,改善了RTI数据管理效率,并成功地应用于自行开发的分布仿真支撑平台AST-RTI中。

High Level Architecture, which is the newest standard of distributed interactive simulation, has facilitated simulation components interoperability and reuse, and Run Time Infrastructure is a software implementation of HLA, whose run-time performance can affect the simulation applications based on it. We defined the resources used in RTI and the problems in resource management are discussed in this paper, then a method to access such resource quickly with low storage cost is proposed, which improved the efficiency of data management in RTI, and the theory has been successfully applied to the design and development of copyright software, AST-RTI, and exhibits good performances.
