<p>A switching matrix has a plurality of inputs and outputs which may be connected to each other. Pairs of inputs (TX) and outputs (RX1, RX2, RX3) are examined sequentially to determine whether a connection can be made across the matrix. If the evaluated input and output are busy (RX1 at time 52, RX2 at time 53) a connection cannot be made, and the input (TX) remains idle. When a connection can be made (with RX3 at time 54) a connection is scheduled, taking into account the time for which that connection has been available 51. Inputs and outputs have controllers which continuously monitor, e.g. by using counters, the time for which connections have been available. Idle time at inputs is reduced, thereby increasing switching capacity. The switching matrix may be one which handles ATM traffic. <IMAGE></p> |
