A Novel Incrementally-Deployable Multi-Granularity Multihoming Framework for the Future Internet

Multihoming practice in the current Internet is limited to hosts and Autonomous Systems (ASs). It is "Connectivity-oriented" without support for user or data multihoming. However, the swift migration of Internet from "Connectivity-oriented" to "Content-oriented" pattern urges to incorporate user and data level multihoming support in architecture designs instead of just through ad-hoc patches. In this paper, based on the authors' previous research experience, they expand the multihoming concepts to both user and data levels based on the "Multiple points of attachment" in a way similar to host multihoming.
