Abstract
A broadband switching system and method switches asynchronously transferred cells of data using a dynamic bandwidth controller to control application of data cells from a number of transmitting end systems to an input port of the system. The dynamic bandwidth controller provides cell buffering from each source and controls output of data cells to the system according to a current cell rate assigned to cells from the respective end system. When an end system begins transmitting data cells, the controller detects the presence of incoming cells and requests bandwidth from a connection admission control forming part of the system. A default cell rate is provided for the end system so that transmission can continue until an appropriate bandwidth is allocated. The controller contains a buffer for buffering cells in this situation. Once appropriate bandwidth has been allocated, cell rate advice information from the connection admission control is fed back to the data bandwidth controller and thence to the transmitting end system to prevent transmission of cells at too high a rate for the available bandwidth.
