The Auckland-VII data set is a 13.5 hours GPS-synchronized ATM cell header trace trace captured with a DAG3 system at the University of Auckland by the WAND research group in July 2001.
The trace data files are available as unidirectional files in durations of 15 minutes time and can be downloaded via FTP or HTTP:
MD5 checksums for verification can be found here.
When downloading the traces, please read the disclaimers. When using these traces for research and publications, please give appropriate credits for the Auckland-VII data set towards NLANR MOAT and the WAND research group. The WAND group wishes to thank Nevil Brownlee and the ITSS operators group for their continuing support of the measurement point.
The traces are in a special format, consisting of a standard Dag timestamp and a 32bit word representing the ATM cell header. Every record thus consists of 12 bytes.

| timestamp seconds |

The University of Auckland ITSS department is operating an OC3c ATM link via Clear Communications (a major New Zealand ISP and competitor to Telecom NZ).
The OC3 link carries a number of Classical-IP-over-ATM, LANE and POTS services.
All cells were captured and immediately processed to extract only the timestamp and header data. No other information was preserved. There is some information available about what VPI/VCI represents which type of traffic, please contact us about any details you may wish to know about.
