The hla standard is consisted of three components : hla rules , hla interface specification and object model template . and the software implementing the hla interface specification is run - time infrastructure , which provides the simulations with seven groups of services ( federation management , declaration management , object management , time management , data distribution management , ownership management and support services ) at the same way as the distributed operation system provides services for applications . but the rti itself is not one part of the hla standard Hla标准由规则、接口规范、对象模型模板三部分组成，而rti ( run - timeinfrastructure ，运行时底层结构)是实现hla标准中接口规范的软件，它以类似于分布式操作系统为应用程序提供服务的方式给仿真应用提供了联邦管理、声明管理、对象管理、时间管理、数据分发管理、所有权管理和支持的服务等七组服务，但是rti本身并不属于hla标准。
