  • Patent number: 6904047
    Abstract: A method for scheduling an input and output buffered ATM or packet switch and, more particularly, to a method for cell-scheduling an input and output buffered switch that is adapted to a high-speed large switch is provided. The input and output buffered switch has multiple switching planes, and its structure is used to compensated for decreasing performance of the input buffered switch resulting from HOL (head-of-line) blocking of the input buffered switch. The input and output buffered switch consists of input buffer modules grouping several input ports and output ports and output buffer modules, and each input buffer module has several FIFO queues for the associated module output buffer modules. In the input and output buffered switch having multiple switching planes, cell scheduling is carried out using a simple iterative matching (SIM) method.
