IDL4HLA: Implementing CORBAIDL Middleware for HLA

摘要

CORBA is a commercial standard for sharing an object's data and methods over a network in an object-oriented, language-independent form. The shareable portion of these objects is specified in an Interface Definition Language (IDL) that serves an interface specification function similar to the headers files common in C, C++, and Ada. HLA is a DoD standard for sharing object attributes and interactions between modeling and simulations systems. Although the HLA currently uses a procedural API, many programs have experimented with middleware products that encapsulate the HLA's common operations into an object-oriented library. Anteon is currently investigating the marriage of an IDL front-end to HLA back-end services. This paper will discuss the middleware s requirements, a comparison to existing middleware products, the high level design, and a few examples of product utilization. By relying heavily on industry standard API s and data models, we expect this approach to take advantage of the best features from both CORBA and HLA without imposing a large training burden on the simulation developer community.
