6、ee related standards for the HLA. It defines the services and interfaces to beused by federates when participating in a federation execution.This new version of the IEEE 1516 HLA was produced in 2004 through 2007 by the HLA Evolved ProductDevelopment Group of the Simulation Interoperability Standard
7、s Organization (SISO). It incorporates anumber of updates based on practical application of earlier versions of the standard. The purpose of the newversion is to better support development, deployment, and net-centricity of distributed simulations.Major new additions include support for Web Services
8、 communication, modular information modelsfederation object models (FOMs) and simulation object models (SOMs), improved extensible markuplanguage (XML) features (XML Schemata as well as extensibility), improved fault tolerance support,support for update rate reduction, and dynamic link compatibility

Also, for the RTI-initiated services, some implicit preconditions are not s
16、tated explicitlybecause the RTI is assumed to be well behaved. For many RTI-initiated services, the “Federate is joined”precondition presumes the “Federate is connected” precondition.As mentioned earlier, all RTI-initiated services are denoted with a (printers dagger) after the servicename.1.4.4 Org
17、anization of this documentThe seven HLA service groups are specified in Clause 4 through Clause 10. Each service is described usingseveral components: Name and description: service name and narrative describing the functionality of the service. Supplied arguments: arguments supplied to the service R
18、eturned arguments: arguments returned by the service. Preconditions: conditions that shall exist for the service to execute correctly. Postconditions: conditions that shall exist once the service has executed correctly. Exceptions: notifications of any irregularity that may occur during service invo
19、cation. Whereverpossible (excepting situations like RTI internal error), exceptions are side-effect free. Exceptions arelisted in order of increasing precedence. That is, if the conditions for more than one exception aremet simultaneous, the RTI shall throw whichever of those exceptions comes later
20、in the exceptionlist. Reference state charts: reference to state chart(s) that are germane to the service.After the clauses describing each of the service groups are a clause describing the MOM and then a clausethat ties the service narratives with the APIs.IEEE Std 1516.1-2010 IEEE STANDARD FOR MOD
