The switching system includes input modules (IM 1 , IM 2 , IMi, IMn) each connected to a switching matrix ( 1 ) and to a corresponding controller ( 2 ). Each input module (IMi) organizes packets that it receives into digital data blocks with a fixed size, and makes transfers of these blocks by successive cycles to the matrix ( 1 ). Each of these blocks is organized into groups of digital data, these groups having corresponding modifiable sizes and being stored according to a predetermined order and associated with the corresponding output ports (OP 1 , OP 2 , OPj, OPn) in the system. Each of these groups is formed of packets to be sent to a single corresponding output port. Any block transfer to the matrix ( 1 ) is accompanied by transmission of information representative of the corresponding sizes of the groups of the transferred block to the said controller ( 2 ), and the groups of each transferred block are switched to their corresponding destination output ports as a function of this information representing the sizes. This system makes it possible to satisfy service quality criteria applicable to switched packets, while limiting the quantity of data to be exchanged between the input modules and the controller. To be applied to telecommunication networks, particularly multiservice networks.
