Network performance evaluation tools play important roles in network researches. However, most tools will cause highly CPU utilization and high monetary cost. Moreover, it is not easy to set up a test environment anytime and anywhere. To solve this problem, we build a lightweight network performance evaluation tool, SDNort, through the OpenFlow architecture. Through our evaluation tool, users can...
Software-Defined Networking (SDN) is an emerging architecture that is ideal for today's high-bandwidth, dynamic network environments. In this architecture, the control and data planes are decoupled from each other. Although much research has been performed into how SDN can resolve some of the most-glaring security issues of traditional networking, less research has addressed cloud security threats,...
With the emergence of various multimedia applications, service and devices, multimedia delivery is expected to become the major traffic of Internet which will keep increasing rapidly. In order to serve such large scale multimedia applications, more and more service providers store their video assets in the cloud and delivery streaming to their consumers cross cloud, for example, YouTube. Along with...
Recently, the need of traffic classification and applications identification has attracted numerous research efforts. Based on statistical attribute analysis, recent research studies employed machine learning algorithms for building traffic classifiers. The machine learning based traffic classification achieves high accuracy and becomes prominent scheme. This paper proposes the framework of cloud-based...
