This is a continuous 6 and a half week GPS-synchronized IP header trace taken using a pair of DAG 3 cards at the University of Auckland Internet access link.

The tap was installed at an OC3 link carrying various Classical-IP-over-ATM, LANE and POTS services. The trace contains all the IP headers of a pair of redundant VPI/VCI's, which connect the University to its ISP. However, for the last week in February the system was only configured to monitor one of the VPI/VCI's so traces prior to March 1 do not include the second ATM channel. This is also the cause for the gap between February 26 and March 1.

Each trace file is named using the following format: yyyymmdd-HHMMSS-[direction].gz. The time and date refers to the local time when the capture was started. The direction refers to which half of the link is contained within the trace. Direction 0 is traffic coming into the University and direction 1 is traffic originating from the University.

All non-IP traffic has been discarded and only TCP, UDP and ICMP traffic is present in the trace. Any user payload within the 64 byte capture record has been zeroed.

The IP addresses in the traces have been replaced using a one-to-one mapping into the 10.0.0.0/8 address space. Each anonymised address was assigned sequentially so the first real-world address observed is mapped to 10.0.0.1, the next new address is 10.0.0.2 and so on. The mapping database was preserved across the entire trace set.

The recommended method for processing these traces is to use Libtrace, which we have developed. There are a number of tools included with libtrace such as a packet dumping utility, a trace format converter (for example, to convert to pcap), a trace splitting/filtering tool and a few statistic generators. We suggest you examine the Libtrace Wiki for more details on the Libtrace tools and the library itself.
