The CAIDA Anonymized Internet Traces Dataset

CAIDA routinely collects traces on several backbone OC192 links: equinix-chicago (since April 2008) and equinix-sanjose (since July 2008). These monthly traces of one hour each are provided to interested researchers on request in pcap files containing payload-stripped, anonymized traffic organized in the annual datasets listed below.

Mainly driven by cost and size issues for disk storage, a decision was made in summer 2010 to reorganize the passive trace datasets on a quarterly schedule: each quarter the best of the three monthly traces is selected; each year only the four selected traces for each quarter are included in the online datasets. For the omitted traces only metadata are retained. These primarily include statistical information, and a breakdown in flow and protocol characteristics.

Start time of trace (UTC)

Stop time of trace (UTC)

Number of IPv4 packets

Number of IPv6 packets

Unknown packets (as fraction of total number of packets)

Transmission rate in packets per second

Transmission rate in bits per second

Link load (as fraction of nominal maximum load for an OC192 link (9.953×10⁹ bits/s)

Average packet size (bytes) (including a link to a graph of the packet size distribution)
