摘要
研究和实现了OPNET半实物仿真模块SITL对实时传输协议的支持.根据系统在环原理,研究了数据包的捕获与转换两个关键技术,对RTP包从虚拟到真实和从真实到虚拟进行了分析.完成了SITL模块对RTP协议的支持,设计了仿真实验并收集了数据包转换延时和吞吐量统计量.结果表明,该功能模块的扩展可以有效测试RTP协议半实物仿真的准确性,为大规模网络仿真提供客观、可靠的依据.
The support to real-time transport protocol （RTP） by system-in-the-loop（SITL） is studied and realized. According to the principle of SITL, data packets capturing and exchanging are investigated. RTP data packets convertion between the simulated network and the real network is analyzed. The function of SITL supporting RTP is realized. In the SITL simulation experiment of RTP protocol, the packet conversion delay and handling capability are collected. The analysis of simulation result and accuracy shows that SITL supporting RTP can test the accuracy of RTP simulation, providing references for SITL supporting user-defined protocol.
