本文报告了我们对一个因特网骨干ATM网络的业务特性的测量和分析。为了有效地利用网络资源，同时满足服务质量的要求，重要的是要了解的业务特性。因此，我们监测流量从流量或应用程序的水平，以细胞之间的链接NTT的开放计算机网络（OCN）和科学信息网络（SINET），这是两个最大的互联网骨干ATM为基础的网络在日本的水平。使用监测的流量，我们还评估了实时模拟的聚合流量的性能。结果表明，性能（信元丢失率）很大程度上不仅取决于链路利用率，但也流的数量，流量大小，和业务组成的应用程序。我们还发现，互联网骨干网的自相似程度并不大。此外，我们澄清了更多的统计复用增益可以在互联网骨干网时，更多的流复用到一个链路上。
This paper reports our measurements and analysis of traffic characteristics in an Internet backbone ATM network. In order to utilize network resource efficiently while satisfying the quality of service requirement, it is important to understand the traffic characteristics. We therefore monitored the traffic from the flow 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 traffic, we also evaluated the performance of the aggregate traffic 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 flows, flow size, and traffic composition in terms of applications. We also found that the degree of self-similarity in the Internet backbone was not large. In addition, we clarified that more statistical multiplexing gain could be obtained in the Internet backbone when more flows were multiplexed onto a link.
