Research interest

  • Network traffic anomaly 
    Nowadays many attractive network services are available for ordinary users through the Internet. Consequently, the growth rate of the Internet traffic is still high, and the traffic includes more and more anomalies such as misconfigurations, failures, and attacks. These improper uses of networks are bandwidth consuming and weaken performance of networks. Anomaly detection in Internet traffic is essential to guarantee legitimate applications for using optimal resources. Detecting anomalies quickly and accurately in network traffic is a hot and challenging research topic in networking.
  • Network traffic visualization
    Intuitive investigation in dump files is conducted using graphical representation of the traffic. Visualization tool displays various information in a way that important features of the traffic are highlighted, thus, main characteristics are understood at a glance. Several levels of detail and aggregation of the traffic can be achieved by visualizing network traffic.
