Network measurement and the DAG card project

Ian Graham
In 1994 the networks research group at the University of Waikato in New Zealand began a programme of network measurement research. To support this we developed network measurement cards, later called "DAG" cards, that could be used to record packet headers on high speed networks with very high precision timing. This seminar describes the process of development of the DAG cards, the DAG architecture and applications, some of the results of the network measurement programme, and the eventual commercialisation of the project to form Endace Technology Ltd.

For the thirteen years until February 2003 Ian Graham was Dean of the School of Computing and Mathematical Sciences at the University of Waikato, New Zealand. His research interests have included radio astronomy, archaeological science and statistics, heraldry, parallel processing using transputers and, most recently, network performance measurement. He is now a professor in Waikato's Department of Computer Science, and Chairman and CTO of the Endace Group.
