摘要
时分多址(TDMA)卫星通信系统具有组网灵活、能够有效地利用卫星资源、支持各类综合业务的接入等优点,目前已经成为国内外卫星发展和研究的热点。针对TDMA卫星通信系统的特点,提出了一种适用于TDMA卫星信道带宽动态变化条件下的传输控制层协议(TCP)加速机制。利用OPNET网络仿真工具对TDMA卫星通信系统进行了仿真建模,仿真结果表明,该TCP加速机制能有效提高IP数据的传输效率。
TDMA satellite communication system has some special advantages.It has flexible network topology,makes effective use of satellite resources and supports integrated service access.It is becoming a hot topic in satellite communication application and development.Base on the characteristics of the TDMA satellite communication system,this paper researches and proposes a TCP acceleration mechanism to suit the change of the TDMA satellite network channel bandwidth.Simulation model of TDMA satellite communication system is established by OPNET network simulation software.The result shows that this TCP acceleration technology can improve the transmission efficiency of IP data effectively.
