Computer Science Technical Report CORBA Based HLA/RTI Design Approach

DMSO’s effort to provide a CORBA based, standard, common real time simulation architecture (High Level Architecture/Run Time Infrastructure, HLA/RTI) [1] for use in military, Civil Air Traffic Control (CATC USA, Europe, Canada), the entertainment industry and NASA has not produced a CORBA based implementation with adequate real time performance. The features that are desirable in an RTI implementation are described. A common HLA/RTI implementation that is suitable for the above applications is one that: 1) meets real-time performance requirements, 2) is the same implementation for all federations or simulations, 3) is implemented using commercial-off-the-shelf (COTS) software and hardware, 4) does not alter or compromise the modularity or present design of the RTI, and 5) allows users and owners of simulation applications and systems to retain control of their systems by not placing RTI functionality in line with their application code.
