Abstract

For reducing the loss of message packets that are transmitted according to an asynchronous transfer mode during the course of virtual connections and which comprise a packet header identifying the respective virtual connection and that are respectively augmented by a sequential auxiliary identifier and that, after multiplication, or transmitted separately via redundant switching matrices of a packet switching equipment, message packets that follow a respective faulty-transmitted message packet are intermediately stored, and that, following the transmission of an error-free message packet which corresponds to the respective faulty-transmitted message packet via a switching matrix that respectively transmits more slowly, the intermediately-stored message packets are forwarded in rapid succession.
