Abstract:
1. A router including a plurality of control units connected in parallel, each control unit having an input connected to a receiving interface and an output connected to a transmitting interface, and performing timing control of outgoing packets to the transmitting interface based on header information of incoming packets from the receiving interface, the incoming packets being stored in a memory and the stored packets being transmitted to the transmitting interface in order of transmission of the outgoing packets based on a result of the timing control, each control unit comprising: a distributing unit provided in the control unit and distributing transmitting sequence information, related to the stored packets in the memory of the control unit, to other control units, the distributing unit determining whether a packet sequence inversion in the control unit occurs, based on a result of comparison of the transmitting sequence information received from the other control units and the transmitting sequence information held by the control unit, and the distributing unit inhibiting the transmission of the stored packets to the transmitting interface when the packet sequence invention is detected.
