Traffic classification is becoming one of the major applications in the data center networks with a lot of cloud services. Recent works about software defined networking (SDN) have found new ways to manage data center networks. However, with the imbalance of the elephant and mice flows is sharpening, the accuracy and efficiency of traffic classification have become more and more important in SDN management...
Distributed Denial of Service (DDoS) attacks are becoming one of the major threats in the distributed data center networks which are loosely connected. Recent work has found new ways to attack network link instead of network servers. However, existing methods have limitations when detecting the link attacks, particularly in data store. To address this issue, in this paper, we propose an attack detection...
The software defined networking (SDN) allows separating control and data plane, which provides better network management and higher utilization for data center network. Among these topical applications in SDN, such as traffic engineering, QoS and network management, there is significant interest on classifying the flows and predict future traffic. Classification plays an important role in SDN, especially...
Large networks are always partitioned into several small networks when deploying software defined networking (SDN). The network partitioning with SDN control planes open many unanswered questions such as latency, reliability, and load balancing. This paper opens the investigation by focusing on two specific questions: given a wide-area network topology, how to partition it into several small SDN domains,...
