This work proposes a solution for software-defined vehicular networks that, combined with Cooperative-ITS messages, aims to manage a multihoming vehicular network with heterogeneous wireless technologies. The work starts with the integration of SDN (through the Open vSwitch (OVS)) in the different interfaces present in the On-Board Units (OBUs) and Road Side Units (RSUs) - ITS-G5, 5G and Ethernet. Then, several mechanisms for the network management, such as the uplink decision logic, are researched and integrated into the OBU's SDN controller. The proposed approach is tested in both laboratory and city environments to assess the correct behavior and robustness of the solution. The results show the advantage of SDN-based multihoming vehicular networks, where different OBU applications are distributed across the different available communication technologies. The overhead introduced by this solution can be considered negligible, and the duration of horizontal and vertical handovers managed by the SDN controller is lower than 20 ms.
