Abstract
A switchover system and method is described. The invention preferably operates in a data packet switching system for transmitting through a switching arrangement data packets that comprise at least a data packet identifier. The switching arrangement comprises at least an active switch card associated to a backup switch card. And the active switch card and the backup switch card receive simultaneously at least a data packet and transmit it to a network adapter device. The switchover system comprises active and backup means for respectively storing at an active and backup data packet address the transmitted at least data packet. It also comprises switchover detecting means coupled to the active and backup storing means for detecting a switchover event, and control means coupled to the active and backup storing means and to the switchover detecting means for setting the backup storing means when a switchover event is detected.
