System and method of tributary time-space switching |
摘要 |
A tributary time-space switch and a method of switching are provided having low memory requirements. The switch includes a number of inputs and outputs. Each of the inputs receives an input data stream carrying tributary payloads from an external input link that are capable of being individually switched in space and time. A write controller causes input columns of the input data stream to be written to a common buffer according to a write pointer. In parallel, a read controller causes the input columns to be read from the common buffer to output columns of an output data stream according to a read pointer. For each of the output columns, the read pointer selects an input column from a limited portion of the buffer that contains a set of the input columns that are capable of being switched in time to the corresponding output column according to a communication protocol.
