摘　　要：针对雷达情报分发对雷达情报网络传输层的需求,分别设计了基于FEC算法和层次信息冗余算法的实时可靠多播协议,并通过OPNET网络仿真工具对协议进行了仿真实验.实验结果表明,两种协议都能满足情报分发的实时性和可靠性要求,层次信息冗余协议操作简单,而FEC协议在平均时延、可靠性和吞吐率方面均优于后者.To meet the demand of radar intelligence network transmission layer for distribution of radar intelligence, two real-time reliable multicast protocols based on both forward error correction （FEC） and layered information redundancy （LIR） were designed respectively, and simulated by OPNET network simulator as well. The simulation results show that both of them meet the demand of reliability and real-time characteristic in intelligence distribution, while LIR protocol is of simple operation, and FEC protocol is much better than LIR for the average delay of packets, reliability, and throughout.
