Abstract(in English) Recently, attention to LEO(Low Earth Orbit)satellite network which is connected to ISL(Inter Satellite Link)is being increased. Building global network which covers the whole earth is possible if seamless connection between present ground network and LEO satellite network by using TCP/IP is possible. However, TCP/IP is originally designed for ground network. Consequently, various problems are expected on LEO satellite network. In this paper, we examine TCP/IP communication which is applied to LEO satellite network. Through this, we clarified that unnecessary fast retransmission occurs by handover during communiction. Furthermore, we propose how to control this unnecessary retransmission by adding few changes to the end terminal using TTL field IP of header. In addition, we evaluate proposed model by simulation. Finally, we show possiblity of congestion control by combining RTT measuring with TTL field information.
