In this paper we present the development and validation of an experimental platform based in open source software and the development of a package for monitoring purposes. The software package with its components is described and validated through a group of tests and examples. These results are the initial support for future research which includes new(More)
This work presents a traffic characterization procedure for Traffic Engineering (TE) in converged networks. An analytical model, focused in a self-similar aggregated traffic characterization is proposed, which considers QoS restrictions for delay metrics. The model, together with evolutionary techniques, is used for the optimization of the link capacity(More)
This work proposes a hybrid traffic model for multimedia networks as a fundamental element in a network planning optimization procedure. The proposed model uses a combination of the fBm (fractional Brownian motion) and Markovian traffic characterization procedures combined with link parameters in order to produce more accurate values of QoS metrics.
