In this paper we propose a protocol that helps TCP connections sustain when a host migrates even between the global network and the private network within a NAPT.
A NAPT (Network Address Port Translator) is often used to let multiple hosts share one IP address. A protocol to support such a type of migration should be designed not on the network layer but on the transport layer, to support host mobility against migration over a NAPT.
We propose a TCP Connection Sustaining Protocol, which consists of three protocols; a protocol to let each hosts know where the other migrates to, extended TCP and a protocol to intermediate TCP connections. These protocols enable TCP connections to sustain even if every host migrates over a NAPT.
