摘要：

We observe temporal fluctuations of information traffic going through a link of the Internet. The fluctuations are characterized by finite correlation times implying that they can be regarded as statistically quasi-stationary. Usual methods in statistical physics become powerful and we confirm a dynamical phase transition occurring between jam and sparse phases with critical behaviors at a non-trivial critical mean density.
