摘要
Link-flooding attack (LFA), as a new type of DDoS attack, can degrade or even cut off network connectivity of a target area. This attack employs legitimate, low-density flows to flood a group of selected links. Therefore, these malicious flows can hardly be distinguished by traditional defense technologies. In our scheme, we first select M routers and upgrade them into SDN switches to maximize the network connectivity. Then, we propose a proactive probe approach to rapidly locate the congested links. Next, our scheme employs a global judgment algorithm to determine whether the network is under LFA or not. Finally, Woodpecker employs the core defense measure that based on the centralized traffic engineering to make the traffic balanced and eliminate the routing bottlenecks that are likely to be utilized by the adversary. We evaluate our scheme through comprehensive experiments. The results show that the bandwidth utilization of LFA-attacked links can be reduced by around 50% and that the average packet loss rate and jitter can be effectively decreased under LFA attacks.
