These PDUs provide information concerning simulated entity states and the types of entity interactions that take place in a distributed interactive simula

4、tion (DIS). The messages defined are for interactions that are primarily within visual range. Future versions of this standard will contain additional PDUs required to exchange information about interactions and functions not currently supported.

Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that

When a document is more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still

11、of some value, do not wholly reflect 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 affiliation with IEEE. Suggesti

Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretation

13、s is brought to the attention of IEEE, the Institute will initiate action to prepare appro- priate responses. Since IEEE Standards represent a consensus of all concerned inter- ests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For th

Introduction (This introduction is not a part of IEEE Std 1278-1993, IEEE Standard for Information Technology-Protocols for Dis- tributed Interactive Simulation Appli

17、cations, Entity Information and Interaction.) This standard is part of a proposed set of standards for distributed interactive simulation (DIS). The relation- ship between this standard, Entity Information and Interaction, and other proposed DIS standards is shown below. Applications I- l- Y Service

18、s and Protocols Defined in Communication Architecture for Distributed Interactive Simulation Physical Medium and Related Protocols _- Documentation relationships This proposed set of standards discusses requirements for simulations participating in a distributed interac- tive simulation. There are s

19、everal elements that make up the DIS environment. Each element is to be addressed by one or more standards. Used together, these standards will define an interoperable simulated battle environment. It should be recognized that these proposed standards will also be applicable to civilian and commerci

20、al applications of DIS. Law enforcement, disaster control, environmental control, and gaming are but a few examples. The main elements to be addressed by these standards are: a) Communications b) Simulation environment c) Fidelity, exercise control, and feedback requirements The scope of this standa

21、rd lies within the first element, communications. Its purpose is to define the data messages that are exchanged between simulation applications. These protocol data units (PDUs) provide data concerning simulated entity states and the types of entity interactions that take place in a DIS exercise. Fu

22、ture versions of this standard will contain additional PDUs required to exchange information about inter- actions and functions not currently supported. The rationale behind the content of this standard is contained in IST-PD-92- I *. A related standard draft, IST-CR-92-6, establishes the requiremen

23、ts for the communication architecture to be used in DIS applications (CADIS). It makes recommendations concerning the communication profiles *Information on references can be found in clause 2 . 111 - that can provide the services to meet those requirements. This standard, along with the CADIS docum

24、ent, provide the necessary information exchange for the communications element of DIS. For the second element, simulation environment, the government of the United States has a draft of a mili- tary standard.

For the third element the required fidelity correlation between simulations in a DIS exercise is addressed in the draft of standard IST-CR-92-8. The proposed method for setup and control of a DIS exe

26、rcise and provid- ing feedback at the end is addressed in the draft of standard IST-CR-92-10, The first edition of this standard defines messages for interactions that are primarily within visual range. It is anticipated that future editions of this standard will provide additional capabilities to s

27、upport other DIS application requirements, such as electronic combat. The area covered by this standard is undergoing evolution. Revisions are anticipated to this standard within the next few years to clarify existing material, to correct possible errors, and to incorporate new related material. At

IEEE Standard for Information Technology- Protocols for Distributed Interactive Simulation Applications Entity Information and Interaction 1. Overview This standard explains the inf

43、ormation technology protocols required for Distributed Interactive Simulation (DIS) applications. This standard is divided into six clauses. Clause 1 provides the scope of the standard. Clause 2 lists references to other standards that are useful in applying this standard. Clause 3 provides defi- ni

44、tions of terms and acronyms that are used in the standard. It is imperative for the user of this standard to thoroughly review these definitions before proceeding on to the other clauses. Clause 4 details key DIS con- cepts that will help in understanding the context of this standard. Clause 5 conta

45、ins requirements concerning the content and use of protocol data units (PDUs) in DIS exercises. Clause 6 defines the various PDUs and their fields. 1.1 Scope This standard is part of a proposed set of standards for DIS applications. Each standard in the proposed set describes one or more of the seve

46、ral elements that constitute the DIS environment. As a whole the set of standards will define an interoperable simulated battle environment. This particular standard addresses the entity information and interaction protocols. This standard defines the data messages, known as PDUs, that are exchanged

47、 on a network between simula- tion applications. The messages defined are for interactions that are primarily within visual range. This stan- dard does not provide information to support other DIS application requirements, such as electronic combat. 1.2 Terminology The following six terms, which are

48、 defined in clause 3, form the basis for understanding the key concepts stated in clause 4. a) Distributed Interactive Simulation (DIS) b) Host computer c) Simulation application d) Simulation entity e) Simulation environment fl Simulation exercise 1 IEEE Std 1278-1 993 IEEE STANDARD FOR INFORMATION
