Multihoming support based on mobile node protocol LIN6

We extend the mobile network architecture protocol "LIN6", to support multihoming, and design a new application program interface (API) that enables an application to support multihoming. The LIN6's addressing architecture makes it possible to support what we call end-to-end multihoming without any inconsistency. In end-to-end multihoming, a fault-tolerant connection can be achieved relying not on routers but on the pair of end-nodes only. The new APIs make it easy to write an application that supports multihoming and robust connections. The extension to the LIN6 protocol and the new APIs give the capability of multihoming to the LIN6 protocol.
