Dynamic flow steering for IoT monitoring data in SDN-coordinated IoT-Cloud services
Heebum Yoon, Seungryong Kim, Taekho Nam, JongWon Kim · 2017
By effectively coupling IoT and Cloud together, we need to enable diversified IoT-Cloud services. To effectively support IoT-Cloud services, it is essential to maintain persistent data transport between IoT and Cloud. Also the emerging Software-Defined Networking (SDN) paradigm can assist flexible flow-centric networking of persistent data between IoT and Cloud. Thus, in this paper, we take an example of IoT-Cloud service realized over miniaturized IoT-SDN-Cloud environment (named as SmartX-mini Playground) and propose the application of SDN-based flow steering to dynamically adjust the overlay data paths for IoT-Cloud services. More specifically, we attempt to combine the overlay data transport of Apache Kafka messages and the underlay flow-based networking coordinated by an ONOS (Open Networking Operating System) SDN controller.
