支持成员动态重用的HLA／RTI扩展

Extending HLA/RTI for dynamical reusability of federates

该文分析了当前HLA成员重用性低的原因,研究了支持成员重用的RTI扩展框架。该扩展框架在HLA/RTI标准框架上,增加一个自适应的中间映射层,可实现不同重用场景下成员固化SOM到联邦FOM间的映射与管理。中间映射层的关键是映射模型构建,该文建立了消息映射算子元模型,实现了映射模型的动态构建,基于自适应中间映射层的RTI扩展框架可有效提高成员重用性,成员在不做改动的情况下,能正确加入到新联邦中运行。实验结果表明了本扩展框架的可行性和有效性。

This study analyzes the reasons for the low reusability of current HLA federates and extends the RTI framework to improve the federate reusability. The extension framework is implemented by adding a self-adapting middle mapping layer to the standard HLA/RTI framework to manage the mapping between the fixed SOM of the federate and the FOM of the federation for various reuse scenarios. The key to the mapping layer is the eonstruction of the mapping model. This paper presents a recta-model for the message mapping operator which can dynamically construct the mapping model. The extension of the RTI framework with the self-adapting middle mapping layer effectively promotes the federate reusability, so a former federate can join a new federation and run correctly. Tests show that this extension framework is feasible and effective.
