ABSTRACT

Network traffic measurement projects at the University of Waikato

Ian Graham, Dept of Computer Science, The University of Waikato, New Zealand

The hardware section of the group has developed a series of monitoring devices for network speeds from 10/100 Mbit Ethernet through OC3/12 POS/ATM to OC48. An OC192 monitor is under development. Using these devices, called DAG cards, the group has collected an extensive library of packet header traces from a variety of network links. These traces are published at the Waikato Internet Trace archive, http://wand.cs.waika to.ac.nz/wand.wits This archive now contains about 5 billion IP headers. The traces have been The group has also contributed to the NLANR MOAT Passive Measurement and Analysis (PMA) project, http://pm a.nlanr.net/PMA/ and to a study of an OC48 link in California http://www.caida.org/analysis/workload/oc48/

This seminar will describe the data collection techniques used to obtain these traces, and some results of trace analysis.

Professor Ian Graham is Dean of the School of Computing and Mathematical Sciences at the University of Waikato, New Zealand. Originally trained as a physicist he gained a PhD in Radio Astronomy from the University of Cambridge, and then worked for fifteen years in archaeological science. He moved into the Department of Computer Science at Waikato in 1986, and served a term as Head of Department before becoming Dean in 1989. His main research interest is in the measurement of network performance. He is one of the founders of Endace Measurement Systems, a company set up to commercialise technology developed at Waikato.
