Members of the committees serve voluntarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every Þve years for revision or reafÞrmation. When a document is more than Þve years old and has not been reafÞrmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reßect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership afÞliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to speciÞc applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O.

IEEE Standard for Distributed Interactive SimulationÑCommunication Services and ProÞles.) Distributed Interactive Simulation (DIS) is a government/industry initiative to deÞne an infrastructure for linking simulations of various types at multiple locations to create realistic, complex, virtual worlds for the simulation of highly interactive activities. This infrastructure brings together systems built for separate purposes, technologies from different eras, products from various vendors, and platforms from various services, and permits them to interoperate. DIS exercises are intended to support a mixture of virtual entities with computer-controlled behavior (computer generated forces), virtual entities with live operators (human in-the-loop simulators), live entities (operational platforms and test and evaluation systems), and constructive entities (wargames and other automated simulations). DIS draws heavily on experience derived from the Simulator Networking (SIMNET) program developed by the Advanced Research Projects Agency (ARPA), adopting many of SIMNET's basic concepts and heeding lessons learned. In order for DIS to take advantage of currently installed and future simulations developed by different organizations, a means had to be found for assuring interoperability between dissimilar simulations. These means were developed in the form of industry consensus standards. The open forum (including government, industry, and academia) chosen for developing these standards was a series of semi-annual Workshops on Standards for the Interoperability of Distributed Simulations that began in 1989. The results of the workshops have been several IEEE standards. These standards provide application protocol and communication service standards to support DIS interoperability. In addition, IEEE P1278.3, Draft, Recommended Practice for Distributed Interactive SimulationÑExercise Management and Feedback, provides user guidelines for setting up and conducting a DIS exercise. The relationship between the component documents comprising the set of IEEE DIS documents is shown in the Þgure below. Used together, these standards and the recommended practice will help to ensure an interoperable simulated environment. Copyright The Institute of Electrical and Electronics Engineers, Inc.

The PDUs provide information concerning simulated entity states, the type of entity interactions that take place in a DIS exercise, and data for management and control of a DIS exercise. IEEE Std 1278.1-1995 also speciÞes the communication services to be used with each of the PDUs. These services are deÞned in IEEE Std 1278.2-1995 . An additional, non-IEEE document is required for use with IEEE Std 1278.1-1995. This document is entitled Enumeration and Bit-encoded Values for use with IEEE Std 1278.1, and is available from the Tactical Warfare Simulation and Technology Information Analysis Center at the Institute for Simulation and Training of the University of Central Florida. IEEE Std 1278.2-1995 deÞnes the communication services required to support the message exchange described in IEEE Std 1278.1-1995. In addition, IEEE Std 1278.2-1995 provides several communication proÞles that meet the speciÞed communications requirements. Together IEEE Std 1278.1-1995 and IEEE Std 1278.2-1995 provide the necessary information exchange for the communications element of DIS. IEEE P1278.3, Draft, Recommended Practice for Distributed Interactive SimulationÑExercise Management and Feedback provides guidelines for establishing a DIS exercise, managing the exercise, and providing proper feedback. This recommended practice is used in conjunction with IEEE Std 1278.1-1995 and IEEE Std 1278.2-1995. Revisions are anticipated to each of these standards and the recommended practice within the next few years to clarify existing material, to correct possible errors, and to incorporate new material. Future versions of these documents will contain information concerning additional interoperability components that are currently in the process of being deÞned.
