ABSTRACT:
The system performs an optimized number of simultaneous transfers of data packets between pairs of units comprising an origin unit and a target unit selected among N data processing units (8). Each data processing unit comprises a set of outbound queues with one outbound queue associated with each one of the data processing units to which it may send data packets, for storing the data packets to be sent by the data processing unit to the data processing unit associated with said one outbound queue. The transfers are performed during a time burst Ti+1 by data switch 6 under control of switching control signals sent to data switch by the units on lines 16-1 to 16-N in response to control out signals generated by scheduler 4 during previous burst time Ti. The scheduler runs a selection algorithm which gives each unit an equal probability to be selected as origin unit in a given period.
