This article proposed an econometric model ARIMA(p, d, q) is presented as a tool for controlling LAN congestion. To achieve this objective should make the revision of the time series as a way to measure, understand and analyze data networks, as well as the behavior of the shares in a stock exchange. So the concept of the time series for actions and data networks to engage with this model propouse congestion control. In order to present a model to test the performance of the model is used to simulate a LAN trace.
