RESUMO

The increase of economic competition in the world has demanded companies rationalize and optimize the use of their resources. Jointly with this fact, the development of new computational and telecommunication facilities in the recent years have promoted some unprecedented evolution of application and increasing necessity of communication services. Both facts have caused remarkable changes in traffic characteristics. Therefore the bandwiih allocation become an important issue for telecommunication networks design. Cell loss probability and cell latency have been two major approaches to estimate the effective bandwidth of communication network connections. Unfortunately, most of methods underestimated values when traffic is self-similar. The goal of this work is to present traffic characterization method for ATM networks, facilitating their bandwidth allocation and design. In this study, we generalize the effective bandwidth estimation method proposed by Kesidis providing a more realistic estimate value whether the traffic is self-similar or not. Experimentally the estimated effective bandwidth is optimized to reduce the impact provoked by traffic highly self-similar and the results are combined with the Le Boudec s approach. For this end, analytical, heuristical and simulation methods were used jointly both in design and validation of the proposed method
