ABSTRACT:
To selectively route stand-by packets in input modules to destination output modules via a switching matrix, distributed arbitration functions are executable by successive arbitration cycles. Each cycle comprises: a first phase executable by each input controller to send each output controller requests representative of the quantities of required stand-by packets; a second phase executable by each output controller to determine the quantity of admissible packets depending on the requests; a third phase executable by a central arbitration unit to determine allowed aggregate quantities depending on all the admissible quantities; and a fourth phase executable by each input controller to determine the allowed packet quantities depending on the admissible quantities and of the allowed aggregate quantities.
