To provide a correct outgoing stream of data packets for each established connection (having identifying number vc/vp) in a data packet switch, which comprises several parallel switching planes, which are identical to each other, there is for each output port for each switching plane and each established connection a buffer arranged to store at least one data packet. When a first data packet arrives to an output port it is immediately tested by a control device for this output port, if this first data packet is the next data packet, which is in turn to be forwarded from the switch. In a first case, when this condition is satisfied, the data packet is forwarded from the switch. In a second case, when this condition is not satisfied, the data packet is stored in the buffer, which is arranged for the connection, to which said data packet belongs, and for the switching plane, through which the data packet has travelled. |
