DIESIS project

The DIESIS project [1] gives the following definition:

HLA (High Level Architecture) is an IEEE standard developed by the United States department of defence [2]. It allows the exchange of information among several and heterogeneous simulators during simulation running. Communications are possible thanks to the RTI (Run Time Interface), which provides a set of services useful for simulations to coordinate their actions and the information exchange. To communicate through the RTI, each simulator must be RTI compliant:

  • By implementing/using a RTI compliant API.
  • By respecting the OMT (Object Model Template) for information (objects, events, etc.) exchange and for specific simulator modelling.
  • By respecting a number of rules concerning communications between simulations and concerning each simulation. The HLA ability can be useful to exchange information between electricity and telecom simulators.
