Today&rsquo ; s mobility management (MM) architectures, such as Mobile Internet Protocol (IP) and Proxy Mobile IP, feature integration of data and control planes, as well as centralized mobility control. In the existing architecture, however, the tight integration of the data and control planes can induce a non-optimal routing path, because data packets are delivered via a central mobility agent, such as Home Agent and Local Mobility Anchor. Furthermore, the centralized mobility control mechanism tends to increase traffic overhead due to the processing of both data and control packets at a central agent. To address these problems, a new Internet architecture for the future mobile network was proposed, named Mobile-Oriented Future Internet (MOFI). The MOFI architecture was mainly designed as follows: (1) separation of data and control planes for getting an optimal data path ; (2) distributed identifier&ndash ; locator mapping control for alleviating traffic overhead at a central agent. In this article, we investigate the validity of the MOFI architecture through implementation and experimentations over the European Union (EU)&ndash ; Korea testbed network. For this purpose, the MOFI architecture is implemented using OpenFlow and Click Modular Router over a Linux platform, and then it is evaluated over the locally and internationally configured EU&ndash ; Korea testbed network. In particular, we operate two realistic communication scenarios over the EU&ndash ; Korea testbed network. From the experimentation results, we can see that the proposed MOFI architecture can not only provide the mobility management efficiently, but also support the backward compatibility for the current IP version 6 (IPv6) applications and an Internet Protocol network.
