Both models may generate signals with the power-law distributions of the intensity of the flow and the power-law spectral density. Furthermore, different distributions of the interevent time of the point process and different statistics of the size of pulses may result in $1/f^β$ noise (one-over-f noise, 1-f noise) with $0.5\lesssimβ\lesssim2$. Combination of the models is applied for modeling of the Internet traffic.9 pages, 6 figures, Presented at Conference on Traffic and Granular Flow 2005, BerlinPhysics and SocietyData Analysis, Statistics and Probabilitytext
