The CAIDA Anonymized Internet Traces 100G Dataset (April 2024 - Present)

CAIDA's passive traces dataset contains traces collected from high-speed monitors on a commercial backbone link. The data collection started in April 2024 to Present. These data are useful for research on the characteristics of Internet traffic, including application breakdown, security events, geographic and topological distribution, flow volume and duration.

This dataset contains anonymized passive traffic traces from various CAIDA's high-speed monitors on high-speed Internet backbone links.
We collect a one-hour trace each month, but due to storage limitations, we select only one of the three traces for each quarter for inclusion in this yearly collection.

Traffic traces in this dataset are anonymized using CryptoPan prefix-preserving anonymization. The anonymization key changes annually and is the same for all traces recorded during the same calendar year. During capture packets are truncated at a snap length selected to avoid excessive packet loss due to disk I/O overload. The snap length has historically varied from 64 to 96 bytes. In addition, payload is removed from all packets: only header information upto layer 4 (transport layer) remains.

The Napatech network cards used to record these traces provide timestamps with nanosecond precision. However, the anonymized traces are stored in pcap format with timestamps truncated to microseconds.

The traces can be read with any software that reads the pcap (tcpdump) format, including the CoralReef Software Suite, tcpdump, Wireshark, libtrace, and many others.
