Mobility management has become a great challenge due to the exponential growth in the number of devices that can connect to home or visited networks, and the need for providing seamless mobility in future generation networks. SDN-DMM (Software Defined Network Architecture for Distributed Mobility Management) architecture has been proposed [11], allowing to separate control and data planes, for the distributed mobility management through bidirectional IP flows. This article reports on aspects related to the implementation of SDN-DMM, conducted with metrics as packet loss, throughput and handover latency, considered in a comparison involving traditional routing and SDN-DMM. The results show the SDN approach not only provides the intrinsic benefits of SDN in comparison with traditional architectures, but also deals with the distributed mode of mobility management in heterogeneous access networks in a simplified and efficient way.
