This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Distributed Interactive Simulation (DIS) system is an ambitious effort to take advantage of the tools of the information age to help improve the efficiency and effectiveness of the U.S. military services. Defined broadly, the DIS system is an infrastructure for linking simulations, simulators and live military systems of various types from any of the U.S. military services at multiple locations to create realistic, complex, virtual 'worlds' for the simulation of highly interactive activities. It poses serious challenges in the areas of technology, interservice coordination, and verification, validation, and accreditation (VV&A). This report concentrates on the validation challenge and presents a framework that encompasses all of the potential uses of the DIS system. It then illuminates the validation or credibility requirements for each type of use. Because of the breadth of the potential uses of DIS, the resulting framework is general enough to address any military application of models and simulations.

Book excerpt: The Distributed Interactive Simulation (DIS) system is an ambitious effort to take advantage of the tools of the information age to help improve the efficiency and effectiveness of the U.S. military services. It involves serious challenges in the areas of technology, interservice coordination, and verification, validation and accreditation (VV & A). The U.S. Army TRADOC Analysis Center (TRAC) has lead responsibility among the services for VV & A of the DIS system. As part of that responsibility, TRAC is sponsoring four efforts aimed at exploring the issues of VV & A of DIS. This report documents one of those four efforts commissioned by the TRAC Director, Mr. Michael Bauman, and is intended to take advantage of previous work done at RAND on exploratory modeling and on validation of models and simulations. The research was conducted in the Force Development and Technology Program of PAND's Arroyo Center, a federally funded research and development center sponsored by the United States Army. The intent of this work is to develop a framework that encompasses all of the potential uses of the DIS system and illuminates the validation or credibility requirements for each type of use. Because of the breadth of the potential uses of DIS, the resulting framework is general enough to address any military application of models and simulations. As such, it should be useful not only to the DIS community, but to developers, users, and consumers of models and simulations throughout the military services.
Download or read book An Automated Approach to Distributed Interactive Simulation DIS Protocol Entity Development written by Michael G. Canterbury and published by . This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: One problem associated with the Distributed Interactive Simulation (DIS) architecture is its limited ability to support real time, simulated engagements of more than 1000 entities. To solve this problem, it is necessary to refine the existing DIS protocol and optimize the form and content of DIS network traffic. Fundamental to this solution is the need to (1) adopt a structured grammar to be used in describing the protocol, (2) provide a means to author and edit refined DIS data elements, and (3) expedite the coding and implementation of related protocol improvements. In simple terms, the problem addressed by this thesis is to meet each of these requisite needs. The approach was to design and build a protocol development tool. This was accomplished in three phases. First, a modified Backus Naur Form (BNF) grammar was formulated for use in modeling DIS data elements. Next, this grammar was applied to the Protocol Data Units (PDU) and data types specified in the current DIS standard. Finally, a tool, the DIS Protocol Support Utility, was developed as a means to automate the process of authoring, editing, and implementing refinements to the DIS protocol. As a result of this effort, the data elements depicted in the current DIS standard have been specified using a BNF- Irke grammar. The Protocol Support Utility has been used to process this grammar and automatically generate the program source code associated with each data element, thus expediting the protocol development process.

Download or read book NPSNET Integration of Distributed Interactive Simulation DIS Protocol for Communication Architecture and Information Interchange written by and published by . This book was released on 1993 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Computer Science Department at the Naval Postgraduate School in Monterey, California has developed a low-cost real-time interactive network based simulation system, known as NPSNET, that uses Silicon Graphics workstations. NPSNET has used non-standard protocols which constrains its participation in distributed simulation. DIS specifies standard protocols and is emerging as the international standard for distributed simulation. This research focused on the development of a robust, high-performance implementation of the DIS Version 2.0.3 protocol to support graphic simulation systems (e.g. NPSNET). The challenge was to comply with the standard and minimize network latency thereby maintaining the time and space coherence of distributed simulations. The resulting DIS Network Library consists of an application program interface (API) to low level network routines, a host of network utilities, and a network harness that takes advantage of multiprocessor workstations. The library was successfully tested on our local network and two configurations of a T-I based internet, the Defense Simulation Internet (DSI), with the Air Force Institute of Technology and Advanced Research Projects Agency. The testing confirmed that the semantics and syntax of the DIS protocol is properly implemented and the latency incurred by the network does not adversely effect the simulation application.

Book excerpt: Current Department of Defense simulation research centers on real-time, interactive simulation of realistic, complex, "virtual worlds" represent the coalescence of a diverse set of virtual, constructive, and live simulations occurring at various locations throughout the world. This effort is collectively known as Distributed Interactive Simulation (DIS). Its purpose is to allow dissimilar autonomous simulation nodes to interoperate in real-time, interactive, distributed simulations. Inter-node communication is achieved by exchanging DIS protocol data units (PDU). To facilitate the development of simulation application programs that use the DIS protocol, the Simulation Methodology Branch of the Advanced Computational and Informational Sciences Directorate, U.S. Army Research Laboratory (ARL), developed a set of DIS software management programs, collectively referred to as the DIS Network Manager. It employs a client-server based architecture, providing a library of software routines to client application programs for creating, handling, sending, and receiving DIS protocol data units.
