Since thetraditional Run-Time Infrastructure (RTI) is not good at supporting these new requirements, an extendedhigh level architecture (HLA) multilayer federation integration architecture (MLFIA), based on the resourcemanagement federation (RMF) and its supporting environment based Service-oriented architecture(SOA) and HLA (SOHLA) are proposed, The idea and realization of two key technologies, the dynamiccreation of simulation federation based on RMF, TH_RTT, an extensible HLA runtime infrastructure(RTI), used at Internet are emphasized.
