一种面向分布式仿真的网络通信构件

通过对仿真数据划分为控制信息和状态信息，提出了运用RTP/RTCP协议进行仿真数据进行传输。为了提高仿真数据传输与处理的性能，分析和讨论了数据缓冲队列、数据包的组装与校验和网络异常检测等关键问题。结合面向对象的框架技术，运用多线程技术，分别设计和实现出了客户端和服务器端的网络通信构件。通过在某分布式空中交通管制系统仿真平台的实际应用表明，该网络通信构件能够满足分布式仿真的应用需求，并且还具备了可重用性、可扩展性和易用性等特点。

Analysis and Design of Network Communication Components for DIS

Simulation data was partitioned into the control and status information, so the simulation data transmission by using RTP/RTCP was proposed to improve the reliability and real timeliness; and data queue, assembly and recognition of the length-variant packet, detection of network exception were analyzed in detail to improve the performance. By using object-oriented framework and multi-thread technology, network communication components were designed and implemented for simulation client side and server side respectively. Through the usage in an ATC simulation platform, these network communication components are proved to be effective for DIS application, and also bear the features of reusability, extensibility and ease of use.
