基于Ethernet的分布仿真实时通信技术研究

Research of Real-time Communication Technique of Distributed Simulation Based on Ethernet

在现有Ethernet网络环境下,为了满足分布仿真系统对网络通信的要求,提出了一种面向分布仿真的实时通信协议。该协议结合TCP和UDP网络协议的优点,采用了点播和广播相结合的混合通信方式、运用了差错控制级别可调技术,实现了一种经济高效的网络数据传输。试验结果表明:使用该协议进行数据通信时,具有实时性好,可靠性高等优点。

Aimed at the demand of network communication to distribution simulation system, a real - time communication protocol of distribution -oriented simulation based on Ethemet is putted forward. Trough combining the advantages of TCP protocol and UDP protocol, using error control technology, adopting the mixed communication mode of unicast and broadcost in the protocol, an economical and effective network data transmission is realized. It has been tested that the protocol has some merit such as real -time communication and high reliability.
