Abstract
A method and an apparatus for the cell loss rate estimation in an integrated network, capable of highly accurate estimation which is not too small compared with the actual cell loss rate. In the apparatus, inputting probability density functions of number of arriving cells and an average number of arriving cells for a prescribed constant period of time; calculating a weighted sum of the probability density functions of number of arriving cells, using weight factors which depend on a buffer capacity of the output buffer and a link capacity of the integrated network; and obtaining an estimation value for the cell loss rate by dividing the weighted sum by the average number of arriving cells. These method and apparatus for the cell loss rate estimation are applied to a method and an apparatus for the call admission control as well as a method and an apparatus for the buffer/link capacity designing.
