Foil 26 Integration of DIS with Object Web Based Computing

From Commodity(Web) Technologies in the service of Computational Grids Argonne Workshop on Computational Grids -- 7-10 Sept 97. by Geoffrey C. Fox


1 DoD modeling community is currently evolving towards the HLA(High level Architecture) framework with the RTI (Run Time Infrastructure) based communication bus.
2 The goal of HLA/RTI is to enhance interoperability across more diverse simulators than in the DIS realm, ranging from real-time to time-stepped to event-driven paradigms.
3 HLA defines a set of rules governing how simulators (federates) interact with each others. Federates describe their objects via Object Model Template (OMT) and agree on a common Federation Object Model (FOM).
4 The overall HLA/RTI model is strongly influenced by the CORBA architecture and in fact the current prototype development is indeed CORBA based.
5 We suggest that next step is to combine CORBA2 (Initial HLA/RTI is CORBA1) with NPS prototype ideas to give a fully object and Web integrated event driven simulation environment.
6 Java3D is natural visualization environment in this scenario
