Approximation of Compressed Flows by Equivalent Stream-Based Flows in Multi-Rate Systems with Compression Mechanism

This paper presents considerations concerning the development of an equivalent model for flows subject to compression mechanisms, namely elastic and adaptive flows. The necessity of constructing such a model stems from the fact that, during the transmission of these flows, their parameters — such as bitrate and/or transmission time, as well as the volume of the transmitted data — vary according to the instantaneous values of the compression coefficient. Accounting for these variations within the analytical model enables the development of precise tools for the analysis and dimensioning of modern IT systems like 5G networks.
