  Software Defined Networking (SDN) has been recently introduced as a new
communication paradigm in computer networks. By separating the control plane
from the data plane and entrusting packet forwarding to straightforward
switches, SDN makes it possible to deploy and run networks which are more
flexible to manage and easier to configure. This paper describes a set of
extensions for the INET framework, which allow researchers and network
designers to simulate SDN architectures and evaluate their performance and
security at design time. Together with performance evaluation and design
optimization of SDN networks, our extensions enable the simulation of SDN-based
anomaly detection and mitigation techniques, as well as the quantitative
evaluation of cyber-physical attacks and their impact on the network and
application. This work is an ongoing research activity, and we plan to propose
it for an official contribution to the INET framework.
