RMIS: middleware for transparent object-oriented modeling in multi-simulator systems

A system of middleware services is proposed to realize transparent object oriented (OO) modeling in multi-simulator systems. Shortcomings of remote procedure call schemes in a multi-simulator setting are identified. The use of simulation time synchronization services is suggested instead. The resulting middleware system supports both asynchronous and synchronous interaction. Remote method invocation scheduling (RMIS) is introduced as the main enabling mechanism. Special naming services are introduced to generate required middleware objects. The middleware system is fully transparent to model objects, which may thus remain deployment neutral. Current results and directions for further research are presented.
