Abstract
Software-Defined Networks (SDN) have gained a great interest among both
academic and industry professionals. As this direction has not yet reached maturity,
there is still a lot of research needed to help make it a dominant industrial
technology choice. This paper presents the current status and identifies the future
trends of SDN networks. Several SDN network topologies are implemented using
Mininet and various benchmarking tools are applied for performance evaluation.
Simulation results show that the global view of the SDN controller greatly
enhances network performance at heavy network traffic loads and allows for
efficient load balancing. On the other hand, the SDN controller represents a single
point of attack vulnerability that requires special security precautions against DoS
and DDoS attacks.
