The CAIDA Anonymized 2009 Internet Traces Dataset

This dataset contains anonymized passive traffic traces from CAIDA's equinix-chicago and equinix-sanjose monitors on OC192 Internet backbone links. This data is useful for research on the characteristics of Internet traffic, including application breakdown,security events, geographic and topological distribution, and flow volume and duration.

Traffic traces in this dataset are anonymized using CryptoPAn prefix-preserving anonymization. All traces in this dataset are anonymized with the same key.

We are aware that some data in this dataset contains more then trivial amounts of packet loss; this has especially been an issue for equinix-chicago direction B. Due to the way the monitoring equipment is set up the synchronization between directions we don't know how well-aligned both directions of a single link are for the equinix-chicago setup. More information on this in the README file in the dataset.

CAIDA makes near-realtime traffic reports available from its passive monitors.

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

Data Use Restrictions

  1. The anonymized traffic traces will not be distributed beyond authorized users.
  2. CAIDA will be notified of the names and email addresses of any persons (and their respective affiliations) assisting in research using the anonymized traffic traces. This includes graduate students and interns.
  3. The IP addresses in these traces are all anonymized to preserve the privacy of end users (hosts) and networks monitored in the collection of the data. The anonymization is prefix-preserving; if the original IP addresses had N bits in common, the anonymized addresses will have those same N bits in common. The traces in a dataset are all anonymized with the same key, so one original IP address that appears in multiple traces in a dataset will appear as the same anonymized IP address across those traces. In so far as possible, privacy of end users (hosts) and networks monitored in the creation of these traces will be respected by the researchers. Researchers will make no attempts to reverse engineer, decrypt, or otherwise identify the original IP addresses collected in the trace. Researchers will also not attempt to extract unanonymized IP addresses from encapsulated headers. Researchers will make no attempts to connect to, probe, or in any other way initiate contact with a machine or machine administrator identified via the anonymized traffic traces.
  4. Anyone who publishes a document (including web pages and papers) that uses data from this dataset must provide CAIDA with a copy of the publication and must cite:
    The CAIDA Anonymized 2009 Internet Traces - <dates used>
    Colby Walsworth, Emile Aben, kc claffy, Dan Andersen,

  5. All users are encouraged, but not required, to include the following attribution in their acknowledgments section:
    Support for CAIDA's Internet Traces is provided by the National Science Foundation, the US Department of Homeland Security, and CAIDA Members.
  6. All users who create a publicly available presentation using data from this dataset must provide CAIDA with a copy of the publication and must use the full name of the dataset ("The CAIDA Anonymized 2009 Internet Traces") in the presentation. Users are encouraged, but not required, to include the url for the dataset (http://www.caida.org/data/passive/passive_2009_dataset.xml).
  7. At the end of the research, or semi-annually (whichever is less), a summary of the research and any findings/conclusions will be reported to CAIDA. If any research is described on the WWW, a URL will be provided. This information is primarily used in reports to our funding agencies.
