Abstract
A system and method for controlling transmission of cells is described. The cells are associated with virtual circuits that either require shaping according to constant bit rate (CBR) or real-time variable bit rate (rt-VBR), or no shaping with transmit selection based on priority (for services other than CBR and rt-VBR). The system transmits the shaped and unshaped traffic using one or more circular control structures. The control structures have time slots at the granularity of the maximum system transmit rate.
