Abstract
Packet loss at a standby server during failover results when the primary fails. There is currently always some amount of packet traffic that is inbound to the primary that is lost during the failover interval. With existing solutions, this packet loss during failover is inevitable. The problem is that when this information is lost, the standby has the state of the last commit, so the standby will have the state information that is old and representative of system state accurately only to the system state at the time of the last commit. One solution is a method in which all inbound data packets targeted to be delivered to a primary software application, such as a virtualized software application, running in a primary virtual machine, are continuously monitored and copied by a Network Replication Device for simultaneous delivery to a backup image of the software application running on a standby system.
