Abstract
A priority selector includes buffers receiving control information relating to data to be transmitted through a data switching apparatus (each buffer is arranged to store control information having a respective one of a predetermined number of priority levels and arranged to deliver an overflow signal when contents reach a first predetermined level), storage storing digital priority symbols representative of different priority levels denoted by control information received by the buffers, a random number generator generating a succession of numbers each of which selects a corresponding priority symbol from the storage, a gate responsive to the receipt of the overflow signal from any one of the buffers to change the priority symbol generated by the storage to that designating the buffer giving rise to the overflow signal to change the priority symbol generated by the storage, and a selector responsive to the gate output to select a buffer output.
