Summary :

According to the wide spread of mobile computer terminals, it is required to connect them to remote networks and to allow them to communicate with home computers and Internet servers. There are some mechanisms studied on the IP terminal mobility, including DHCP which assigns IP addresses dynamically and Mobile-IP which supports seemless mobility. However, there are some problems identified for those methods on compatibility with existing IP terminals, route optimization and compatibility with firewall systems. So we have proposed a virtual subnetwork system which can accommodate existing IP routers and terminals without any modifications, and which selects an optimal route for the communication with networks other than the home network. This paper describes the mechanism and the results of implementation of our system.
