Description

Quantitative grasp of network traffic characteristics is important in designing and operating the information network system. Statistical modeling of the network traffic change enables a large scale computer simulation of a complex network system before actual system development and help efficient design and evaluation of the target system. This paper proposes a method to characterize the statistical properties of the network traffic occurrences. A test for nonstationary Poisson hypothesis using a continuous time scaling is introduced and applied to the real data. The analysis showed that the request occurrences fit well with nostationary Poisson process.
