Abstract

The advent of computer networking has spawned a wide variety of applications and technologies. Among the most exiciting and pro1nising of these is Distributed Interactive Sin1ulation (DIS). This technology involves the interconnecting of simulated (virtual) environ men ts which allow participants in one simulation to interact, in real time, with those in another simulation, and observe their interactions by means of out-thewindow views of the individual simulators. The key to the evolution and worldwide acceptance of this DIS technology will be the adoption and integration of standard computer networking methodologies (i.e., Open Systems Interconnection (OSI)) into the overall DIS system communications architecture design. This paper presents results obtained from research into the building of a prototype communications architecture for the DIS application utilizing the ISO Development Environment (IS ODE). The IS ODE is a software implementation of the upper three layers of the OSI protocol suite, which runs on UNIX-based workstations. ISODE uses the Transmission Control Protocol/Internet Protocol (TCP /IP) lower layer communications protocols supplied by most UNIX systems to perform the actual intercomputer communications over Ethernet. The purpose of !SODE is to provide a working environment in which to experiment with the upper OSI stack layers. ISODE is a public domain software package and source code is provided to allow for modification of the software. This research thesis presents the following: 1) a description of the DIS application and its requirements; 2) a discussion of OSI concepts and their applicability to the DIS application; 3) a brief overview of the ISO Development Environment and its services and facilities; 4) a description of the prototype DIS architecture developed using !SODE; 5) a discussion of the experiment and test plan for evaluating the prototype DIS architecture; 6) data obtained and analysis thereof; and, 7) conclusions drawn from this research.
