Performance improvement of TCP over satellite link based on the express transport protocol
基于快速传输协议实现卫星TCP性能的改善

In the network applications over satellite communication system,the TCP performance over satellite link is poor.The splitting TCP mechanism,which is widely applied,can improve the end-to-end performance of TCP.How to choose transport protocol for satellite link determines the performance of whole mechanism.The eXpress Transport Protocol(XTP),adopted in wire network,is a high speed transport protocol.After deep research for the protocol,it was found that XTP could be applicable to satellite communication.So XTP was proposed to be adopted as transport protocol on satellite link in splitting TCP mechanism.Experiment results show that the proposal can significantly improve the TCP performance over satellite link.
