PACKET TRANSFER SYSTEM AND METHOD, DEVICE AND PROGRAM CONSTITUTING THE SYSTEM, AND RECORDING MEDIUM

摘要

It is possible to shorten the communication route between a mobile terminal and a server by IP. A node having an encapsulated address list is provided in the communication route between the mobile terminal and the server and the server registered in the list is encapsulated when transferred. This encapsulation is released before the process performed by the server. At this time, a binding list correlating an internal transmission source address with an external transmission address is generated and a response from the server is transmitted to the external transmission source registered in the binding list.
