一个DIS实时通讯网络的设计与实现

以一个ＤＩＳ（分布交互仿真）实时网络的设计和开发过程为背景，研究了ＤＩＳ实时网络开发中的几个问题。在进行实时ＤＩＳ网络规划时，采用了多点传送的通讯服务方式，保证每个仿真应用只发送变化的信息，只处理与自身相关的信息。指出了进行数据的实时传输格式定义时应注意的几个问题，这些数据定义必须支持多种不同的操作系统和平台。最后给出了开发ＤＩＳ实时通讯软件的方法，包括通讯协议和应用编程接口的选择。

Design and Implementation of a Real-Time DIS Network

Some problems in developing a DIS real time network are researched on the basis of the design and development process of a DIS real time network. Multicast mode communication services are considered in making a layout for a real time network. In a DIS network, only changed messages should be sent to the other simulation applications, and only the messages related to the local application should be dealt with. Several considerations in defining the data transmitting formats are given, these definitions must be available on different type of operating systems and platforms. The methods of developing DIS real time communication software are described, including the choice of communication protocols and the application programming interface.
