SANTT: Sharing Anonymized Network Traffic Traces among Researchers

Current Internet research suffers from limited information available from public network traffic traces due to the privacy concern of ISP and lack of effective trace distribution systems. In this paper, we present our SANTT (sharing anonymized network traces) system to share valuable network traffic traces safely and widely. SANTT employs a novel prefix-preserving anonymization method to sanitize privacy information in packets and takes advantage of specific high-speed traffic capturing hardware. After removing privacy information, SANTT distributes the traces by multicast, which makes it easy for researchers to access. The experimental results show that SANTT implemented on IXP2400 platform can process the fastest traffic rate (1,1953,125 PPS) offered by Gigabit links with high accuracy and stability
