¿µ¹®³»¿ë¿ä¾à This standard introduces a reference model of Failover Manager and describes the terms and requirements of redundant architecture, including heartbeat processing to detect the master¡¯s failure from the backup, handshaking to negotiate the mode transition between the master and backups, and mode transition processing between processes within a device. The synchronization and recovery of the application¡¯s session information which is running within an embedded system is not in the scope of this specification.
