Verification of aggregated flows in OpenFlow networks

Recently, the automatic test packet generation (ATPG) tool is proposed to verify a network for error conditions (e.g., incorrect firewall rules, software, hardware, and performance errors). However, this tool is not able to verify aggregated flows (i.e., flows having wildcards in some of their fields) for matching issues. In this paper, we propose a mechanism to verify aggregated flows in OpenFlow networks. In the demonstration, we verify aggregated flows installed in an emulated pan-European topology using our proposed mechanism.
