摘要 深入分析了卫星网络链路的基本特性,在分析目前卫星网络数据链路传输控制协议性能的基础上,提出了卫星链路最佳帧长的概念,并结合Go-Back-N和SRARQ协议,从理论上计算出了给定链路环境下最佳帧长的取值。仿真结果表明,采用理论最佳帧长能显著提高数据链路传输协议的吞吐率,提高卫星网络链路带宽利用率。 This paper analysed the basic character of satellite network link in detail, proposed a optimal frame-length concept based on the analysis on satellite network data link protocol, such as Go-Back-N ARQ and selective repeat ARQ protocol, and proposed the theoretic computing method of the optimal frame-length in specific link conditions. Simulation results show that using the optimal frame-length can greatly improve the throughput performance and link utilization of satellite network data link transfer protocols.
