This device receives several cell streams characterised by different cell loss rate performances and comprises means for recognising that a cell loss is inevitable when the buffer memory is full, as well as means for deciding that an incoming cell should be recorded in the buffer memory instead of another cell which will be lost. It furthermore comprises means (CF1..., CFi..., CFn) for associating with each cell stream (FC1..., FCi..., FCn) a dynamic indication of cell loss balance (CLF1..., CLFi..., CLFn), which is a function of a cell loss performance (Ni) allotted to this stream and cell losses (RTi) actually noted for this cell stream, and means (SCDA) for selecting a cell stream, especially by comparing the said dynamic indications of cell loss, and for causing as a consequence the incoming cell to be recorded in the buffer memory instead of a cell of the selected cell stream. <IMAGE> |
