Measurement Based Modeling of Quality of Service in the Internet: A Methodological Approach
نویسندگان
چکیده
This paper introduces a new methodology for analyzing and interpreting QoS values collected by active measurement and associated with an a priori constructive model. The originality of this solution is that we start with observed performance (or QoS) measures and derive inputs that have lead to these observations. This process is illustrated in the context of the modelling of the loss observed in an Internet path. It provides a powerful solution to address the complex problem of QoS estimation and network modelling. Keywords—Quality of Service, Internet, Modelling, Measurement based inference, Hidden Markov Model.
