A microscopic description of packet transport in the Internet by using a simple cellular automaton model is presented. A generalised exclusion process is introduced which allows to study travel times of the particles (‘data packets’) along a fixed path in the network. Computer simulations...

The effect of additional input and output sites (as a connection to other roads) on the traffic flow in a cellular automaton model on a road with open boundaries is investigated. For a very low value of probability p of the velocity fluctuation of the vehicles, the 1/fα fluctuations are...
