Mobility becomes an increasingly important aspect of communication for the Internet. However, the current Internet protocol, IP, was not originally designed to support mobility over the Internet. Mobile users currently suffer from connection disruption when they move around, and the device switch the connection between different wireless technology (perform a vertical handoff). While the IETF Mobile IPv4 (MIPv4) and Mobile IPv6 (MIPv6) solutions have been defined for sometime, and implementations are available, they have seen little deployment due to its complexity. We propose an alternative approach, called the Identifier-Locator Network Protocol (ILNP). ILNP can be implemented by enhancing IPv6 header, named ILNPv6, therefore could be deploy over the current IPv6 network infrastructure without require any changes. Only the mobile host need to be upgraded to understand the new addressing scheme. We have created an overlay implementation of ILNPv6, and our performance evaluation shows that ILNPv6 has a good potential to enable IP mobility through the Internet. The implementation of ILNPv6 in system kernel is an on-going work.
