✦ Synopsis

This paper reports our measurements and analysis of traf®c characteristics in an Internet backbone ATM network. In order to utilize network resource ef®ciently while satisfying the quality of service requirement, it is important to understand the traf®c characteristics. We therefore monitored the traf®c from the ¯ow or application level to the cell level on a link between NTT's Open Computer Network (OCN) and the Science Information Network (SINET), which are two of the largest Internet backbone ATM-based networks in Japan. Using the monitored traf®c, we also evaluated the performance of the aggregate traf®c by real-time simulation. Results show that the performance (cell loss ratio) greatly depended not only on link utilization but also on the number of ¯ows, ¯ow size, and traf®c composition in terms of applications. We also found that the degree of self-similarity in the Internet backbone was not large. In addition, we clari®ed that more statistical multiplexing gain could be obtained in the Internet backbone when more ¯ows were multiplexed onto a link.
