The generic phase transition from a phase of freely flowing traffic of electronic data packets to a congested phase is studied in a very simple model. Here the network is an oriented square lattice. Packets are randomly introduced at the nodes located at one boundary with a certain posting rate,...

The Internet is one of the largest and most complex communication and information exchange networks ever created. Therefore, its dynamics and traffic unsurprisingly take on a rich variety of complex dynamics, self-organization, and other phenomena that have been researched for years. This paper...

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...
