Analysis of link discovery service attacks in SDN controller

Software-Defined Networking (SDN) allows scalable and flexible network management without requiring expensive hardware changes. However, this technology is relatively new and creates novel security risks. In this paper, we investigate the vulnerability of link discovery service in SDN controller, which is a critical service provided by the control layer for the proper functioning of applications and network services. We also discuss the potential attacks on link discovery service, which are verified via experiments.
