新IEEE标准-已被取代。 取代。修订版被重新命名为1278.1。定义了在仿真应用程序之间交换的数据消息，称为协议数据单元（PDU）。这些PDU提供有关分布式交互仿真（DIS）中模拟实体状态和实体交互类型的信息。定义的消息主要用于可视范围内的交互。本标准的未来版本将包含交换当前不支持的交互和功能信息所需的附加PDU。

New IEEE Standard - Superseded. Superseded. Revision was redesignated 1278.1. Data messages, called protocol data units (PDUs), that are exchanged between simulation applications are defined. These PDUs provide information concerning simulated entity states and the types of entity interactions that take place in a distributed interactive simulation (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.
