This demo paper presents an innovative SDN-based approach to deploying the Internet of Things (IoT) applications for Smart Cities. The Poznan Supercomputing and Networking Center (PSNC), NoviFlow and Spirent have jointly developed a demonstration showing how programmable SDN infrastructure can be used to significantly simplify the onboarding and provisioning of end-to-end IoT solutions for use in multi-tenant networks. The demo features a dynamic global view of the deployed IoT resources with their associated network connections, and the use of OpenFlow Experimenter-based extensions to trigger automated detection and onboarding of IoT devices (“things”) as well as the insertion of metadata into IoT device flows to automate service provisioning.
