一种适合于深空星际互联网的传输控制协议

摘要

目前国内外已经开展了大量针对同步卫星互联网的传输控制技术研究,提出了很多传输控制协议方案.然而,这些协议方案在信道条件更加恶劣的行星际互联网中的性能表现并不理想.针对深空通信信道特点,在TP-Sa-tellite协议的基础上提出了TP-Satellite+协议.仿真表明,TP-Satellite+协议在月球与地球之间的行星际互联网中,不仅能够有效对抗信道误码,节省反向链路资源占用,而且能缩短连接建立时间,提高行星际互联网的网络性能.%Now,many international groups and researchers have studied the transport protocol for GEO IP networks, and many solutions have been proposed. However,due to the worse channel situation than that of GEO IP networks, the performance of these solutions degrades significantly in Inter-planet IP networks. A new transport protocol,TP-satellite + ,was proposed for deep space Inter-planet IP networks. Simulation results show that TP-Satellite + can resist the channel errors,reduce the setup time and the bandwidth used in the reverse path, enhance the performance of Inter-planet networks.
