Middleware for real-time distributed simulations

Distributed simulation applications often rely on middleware to provide services to support their execution over distributed computing environments. Such middleware spans many levels, ranging from low-level support for data transmission through object request brokers to higher level, simulation specific functionality such as time management. We discuss design alternatives for realizing such middleware for hard real-time (HRT) distributed simulations such as hardware-in-theloop applications. An implementation of a real-time runtime infrastructure (RTI) middleware is described, and its performance compared against a non-real-time implementation. The context for this work is the High Level Architecture standard that has been defined by the U.S. Department of Defense.
