CASTBA: Internet Traffic Measurements over the Spanish R&D ATM Network

Variability and unpredictability are probably the only well known characteristics of Internet traffic. These two aspects considerably hinder any serious attempt to model the Internet traffic behaviour. As a result, the dimensioning and the management of the underlying network resources are extremely difficult. New integrated services IP networks based on broadband transport technologies like ATM are not exceptions of this problem. Several issues, like network performance evaluation, applications quality of service requirements, users accounting, etc, over these networks are of increasing interest for both research community and network operation companies.
