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

Abstract-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 our previous research experience, we expand the multihoming concepts to both user and data levels based on the "multiple points of attachment" in a way similar to host multihoming. We propose a new incrementally-deployable multihoming framework by introducing a "realm" concept. The high-level user and data multihoming support can be built on top of the host and AS level multihoming in an incrementally-deployable and flexibly-assembled manner. Realms form a hierarchy of functionally dependable blocks. We define a new dimension of building block--slice which is an incrementally implementable functional unit for multihoming. Besides the long-term support for user and data multihoming, the first step deployment of the new framework is also able to address the short-term routing scalability challenge by reducing the total inter-domain routing table size gradually

A Survey on Handover Management in Mobility Architectures

This work presents a comprehensive and structured taxonomy of available techniques for managing the handover process in mobility architectures. Representative works from the existing literature have been divided into appropriate categories, based on their ability to support horizontal handovers, vertical handovers and multihoming. We describe approaches designed to work on the current Internet (i.e. IPv4-based networks), as well as those that have been devised for the "future" Internet (e.g. IPv6-based networks and extensions). Quantitative measures and qualitative indicators are also presented and used to evaluate and compare the examined approaches. This critical review provides some valuable guidelines and suggestions for designing and developing mobility architectures, including some practical expedients (e.g. those required in the current Internet environment), aimed to cope with the presence of NAT/firewalls and to provide support to legacy systems and several communication protocols working at the application layer

Mobile Oriented Future Internet (MOFI)

This Special Issue consists of seven papers that discuss how to enhance mobility management and its associated performance in the mobile-oriented future Internet (MOFI) environment. The first two papers deal with the architectural design and experimentation of mobility management schemes, in which new schemes are proposed and real-world testbed experimentations are performed. The subsequent three papers focus on the use of software-defined networks (SDN) for effective service provisioning in the MOFI environment, together with real-world practices and testbed experimentations. The remaining two papers discuss the network engineering issues in newly emerging mobile networks, such as flying ad-hoc networks (FANET) and connected vehicular networks
