This article offer an econometric model that is presented as a tool for controlling LAN congestion and take decision in service. To achieve this objective it should make the revision of the time series as a way to measurement, understand and analyze data networks, as well as the behavior of the shares in a stock exchange. So the concept of the time series of actions and data networks to engage with this model planet congestion control. In order to present a model for test the performance of the model is used to simulate a LAN trace.
