Description
Summary:Summary Mobility management applied to the traditional architecture of the Internet has become a great challenge because of the exponential growth in the number of devices that can connect to the network. This article proposes a Software‐Defined Networking (SDN)‐based architecture, called SDN‐DMM (SDN‐Distributed Mobility Management), that deals with the distributed mode of mobility management in heterogeneous access networks in a simplified and efficient way, ensuring mainly the continuity of IP sessions. Intent‐based mobility management with an IP mapping schema for mobile node identification offers optimized routing without tunneling techniques, hence, an efficient use of the network infrastructure. The simplified mobility control API reduces both signaling and handover latency costs and provides a better scalability and performance in comparison with traditional and SDN‐based DMM approaches. An analytical evaluation of such costs demonstrated the better performance of SDN‐DMM, and a proof of concept of the proposal was implemented in a real environment. In this work, the SDN‐DMM solution was developed for management of active IP sessions of mobile users that move between heterogeneous network access using a Mobility Intent in the control plane that handles IP Flow for the adjustment of data plane, according with the mobility. The analytic evaluation presented shows that SDN‐DMM promotes a better performance of handover latency and signaling costs, since it does not cause non‐optimized routing and optimizes control messages flow.
