This is a continuous 4 and a half day GPS-synchronized IP header trace taken using 3 DAG 3 cards to capture traffic simulataneous at three different points in the University of Auckland Internet infrastructure.
A router connects the ISP ATM switch to a 100 Mbps Ethernet hub (Allied Telesyn CentreCOM FH812u V2i), which is linked via the firewall to a second identical hub. The very first trace, however, was taken when the DMZ was still working at 10 Mbps utilizing two 3Com hubs instead of the Allied Telesyn types. One pair of DAG 3 ATM cards tapped the link between the ISP and the ATM switch. A DAG 3 Ethernet card was connected with its port 0 to a hub outsize DMZ and with its port 1 to a hub inside DMZ. With this configuration, the entirety of the University's Internet traffic is being monitored.
Each trace file is named using the following format: yyyymmdd-HHMMSS-[format][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. The Ethernet traces have their direction prefixed with the letter 'e' to signify their capture format. The ATM traces have no such letter.
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 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.
