SDNort: A Software Defined Network Testing Framework Using Openflow

摘要

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 generate high throughput traffic to testing targets and collect related statistics via OpenFlow commands. Furthermore, users can easily customize testing packets for application evaluation. Finally, we virtualize our work as a VNF (Virtual Network Function) and deployed to a cloud system.
