Abstract
A bandwidth estimation in a resource of a data communication system. After a data unit in a data flow has been received, a recent pulse density for the data flow over a period that includes the received data unit and starts from a time point that precedes the received data unit in the flow is computed. An overall pulse density is computed based on the computed recent pulse density and a previous overall pulse density computed earlier for the data flow. The computation of the overall pulse density is based on values of the computed recent pulse density and the previous overall pulse density. The values are weighted relative to each other. The used bandwidth is estimated based on the weighted overall pulse density.
