UNA: a new internet architecture for user-level multi-homing and mobility

Abstract

Host multi-homing and mobility in the Internet have become a trend due to the widespread wireless services and broad access methods. Meanwhile, with more and more devices join in the Internet, it will be common that one user has multiple devices online. So users will also desire to be multi-homed and mobile across not only addresses but also devices. To provide such support, we present a new network architecture called UNA (User-centric Network Architecture) to achieve user-oriented communications. UNA will make communications completely independent of data delivery, which offers the basis of both network and user level multi-homing and mobility. We first show the general design of UNA including the introduction of new namespaces. Then UNA-I is presented as an illustration to complete the architecture with mapping, resolution and indirection schemes. At last we describe the instantiation of UNA under LTE framework with some security enhancements. However our work is far from complete and in this paper we focus on expressing the new idea.
