Abstract

Message packets are forwarded via a packet switching equipment which comprises at least two redundant switching matrices to serving ports connected thereto, the message packets comprising a packet header identifying a respective virtual connection and being transmitted on offering trunks according to an asynchronous transmission method during the course of virtual connections. A message packet group having a plurality of identical message packets corresponding in number to the plurality of redundant switching matrices by multiplication for each of the message packets transmitted on one of the offering trunks during the course of a virtual connection. An identical auxiliary identifier that changes for successive message packet groups is thereby attached to each of the message packets of a message packet group. The message packets of a message packet group are subsequently separately transmitted via the redundant switching matrices in the direction toward the serving port considered for the respective virtual connection. After such a transmission, only one of the message packets of a message packet group is forwarded to the serving port with reference to the auxiliary identifier respectively attached to the message packets.
