Abstract
In an ATM network, a traffic shaping system is provided with a number of timing subchains each having slots at which cells are queued and each having a pointer to specify the readout of cells at a slot. The system eliminates the necessity for providing large numbers of slots for low data rate traffic while at the same time accommodating high data rate transmission by moving pointers for low data rate traffic at slower rates than pointers for higher data rates. In one embodiment, this is accomplished by increasing the time scale for slots far away from the current time by moving the time pointer increasingly slower for ever more distant slots. When a pointer is at a slot, cells queued at this slot are moved to a slot in the next prior subchain, with cells in the top subchain transmitted when selected by the associated pointer.
