Software Defined Network (SDN) is a new paradigm in network architecture. The basic concept of SDN itself is to separate the control plane and forwarding plane explicitly. In the last few years, SDN technology has become one of the exciting topics for researchers, the development of SDN which was carried out, one of which was implementing the Internet of Things (IoT) devices in the SDN network architecture model. Mininet-IoT is developing the Mininet network emulator by adding virtualized IoT devices, 6LoWPAN based on wireless Linux standards, and 802.15.4 wireless simulation drivers. Mininet-IoT expands the Mininet code class by adding or modifying functions in it. This research will discuss the performance of the 6LoWPAN device on the internet of things (IoT) network by applying the SDN paradigm. We use the Mininet-IoT emulator and the Open Network Operating System (ONOS) controller using the internet of things (IoT) IPv6 forwarding. Performance testing by comparing some of the topologies of the addition of host, switch, and cluster. The test results of the two scenarios tested can be concluded; the throughput value obtained has decreased compared to the value of back-traffic traffic. While the packet loss value obtained is on average above 15%. Jitter value, delay, throughput, and packet loss are still in the category of enough, good, and very good based on TIPHON and ITU-T standards.

Software Defined Networking (SDN) technology increases the evolution of Internet and network development. SDN, with its logical centralization of controllers and global network overview changes the network's characteristics, on term of flexibility, availability and programmability. However, this development increased the network communication security challenges. To enhance the SDN security, we propose the BCFR solution to avoid false flow rules injection in SDN data layer devices. In this solution, we use the blockchain technology to provide the controller authentication and the integrity of the traffic flow circulated between the controller and the other network elements. This work is implemented using OpenStack platform and Onos controller. The evaluation results show the effectiveness of our proposal.
