METHOD AND APPARATUS FOR REALIZING COMMUNICATION TAKE-OVER

摘要

A method and an apparatus for realizing the communication take-over. The route protocol message from the neighbor router is received synchronistical by the main processing unit and the spare processing unit. The main processing unit and the spare processing unit are parallel acting. The spare processing unit maintains the local data according to the protocol message and sends the short answer message to the main processing unit. The main processing unit then maintains the local data according to the protocol message in order to update the local data of the main processing unit and the spare processing unit synchronistical and congruous.
