IEEE 1278.1A-1998 pdf download IEEE Standard for Distributed Interactive Simulation- Application Protocols
1.2 Scope This standard is part of a set of standards and recommended practices for DIS applications. Each standard and recommended practice in the set describes one or more of the elements that constitute the DIS environment. As a whole, the set of standards and recommended practices defines an interoperable simulation environment. This particular standard addresses the application protocols.
1.3 Purpose This standard defines the data messages, known as PDUs, that are exchanged on a network among simulation applications. The messages are organized within specified domains called protocol families. The protocol families included in this standard include Entity Information/Interaction, Warfare, Logistics, Simulation Management, Distributed Emission Regeneration, Radio Communications, Entity Management, Minefield, Synthetic Environment, Simulation Management with Reliability, Information Operations, Live Entity Information/Interaction, and Non-Real Time. Future versions of this standard may contain additional protocol families or PDUs to exchange information about interactions and functions not currently supported.
1.4 Terminology
The following terms, which are defined in Clause 3, form the basis for understanding the key concepts stated in 1.6:
a) DIS
b) Host computer
c) Simulation application
d) Simulation entity
e) Simulation exercise
f) Simulation environment
1.5 Conventions used in this document
The following conventions are used in this document:
a) All numeric values specified in this standard are listed in base ten unless otherwise noted by the suffix (H), which denotes a hexadecimal number.
b) Terms written in all capital letters are symbolic names. The values assigned to the symbolic names are given in 6.1.8.
c) If a term in italics precedes a PDU name, it is used to more clearly and easily define the use of the PDU.
d) The names of fields in PDUs and the names of records are capitalized.
e) All units within PDUs use the International System of Units (SI) (see IEEE/ASTM SI 10™) except when modeling a system that complies with another standard that requires different units.
f) Enumeration fields have values and descriptions defined in SISO-REF-010. The table for each enumeration is identified by a Unique Identifier (UID) in the form “[UID nnn]”. In this standard,references to SISO-REF-010 tables use the same UID syntax; for example, “see [UID 874]”.
g) World coordinate axes are denoted with uppercase X, Y, and Z. Entity (body) and object coordinate axes are denoted with lowercase x, y, and z.
1.6 Key concepts
1.6.1 Introduction
This subclause contains details of key DIS concepts that will help the reader understand the context of this standard. This information is of a general or an explanatory nature that may be helpful, but it is not mandatory.
