Conclusion and Future Work
In this paper, we propose Woodpecker to mitigate a new kind of DDoS attack—LFA. This scheme uses a heuristic algorithm to select a group of switches to upgrade into 1040 SDN-enabled switches. With the help of global view and data plane triggers, Woodpecker can fast locate the congestion and determine whether LFA causes the congestion through the global congestion information. To mitigate the LFA, Woodpecker enforces global traffic engineering 1045 to eliminate the bottleneck links. We evaluate the effectiveness of our scheme with the real topologies and get inspiring results. In our future work, we will migrate Woodpecker to a hardware testbed with an industrial-level controller, and 1050 evaluate the suitability of our system in real life. Moreover, we will increase the versatility of the system to handle more types of DDoS attacks.
