Speech Title: Information-centric TCP Architecture for Terrestrial-Satellite-Integrated Internet
Abstract: TCP is an end-to-end transport protocol of Internet. However, as the physical layer of terrestrial link and satellite link are discrepant, it is still an unsettled problem to design a one-size-fits-all TCP protocol for terrestrial-satellite-integrated network. This paper proposes one novel Information-centric TCP architecture for Terrestrial-Satellite Internet, ICN-TCP, which provides segmented congestion control, in-path packet retransmission and TCP multicast/broadcast. It supports transparent proxy, which connects terrestrial network with satellite network transparently with segmented congestion control. It also has TCP-embedded cache, which recovers lost packets from the nearest TCP cache. It also supports stateless Request-Response transmission, which enables TCP multicast/broadcast. ICN-TCP is specially designed for satellite link with high delay, asymmetric link, frequently handover and unreliable transmission.
