COMBINING THE BURST AND CELL SCALES The finite-capacity buffer is a fundamental element of ATM where cells multiplexed from a number of different input streams are temporarily stored awaiting onward transmission. The flow of cells from the different inputs, the number of inputs, and the rate at which cells are served determine the occupancy of the buffer and hence the cell delay and cell loss experienced. So, how large should this finite buffer be? In Chapters 8 and 9 we have seen that there are tw
