PARRA LEON, Andrés; PIEDRAHITA, Elkin M  e  SALCEDO, Octavio. On-Off model applications to communication networks aggregated traffic. Tecnura [online]. 2011, vol.15, n.30, pp.129-147. ISSN 0123-921X.

The models to recreate traffic traces generated in a communications network can be used in predictions and estimates of traffic in order to optimize the use of network resources, one of these is the model On/Off, which allows describing the behavior of aggregate traffic by one or more sources of information. The importance of this article focuses on the impact that this model has been applied to various communications technologies, for this are evaluated and contrasted different types of documents proposed by several authors. Based on the results, arguably Models On/Off are still in place for traffic modeling, and can be applied at any level of ISO/OSI model. Also, the results observed indicate that depending on the type of power On/Off (single or multiple) the approaches vary greatly, and the mathematical complexity that can have models with source multiplexing On/Off could be a constraint to take into account in its implementation.
