ABSTRACT:
Methods of transparent connection failover allowing a remote computer (i.e., a client), to continue to use a network connection to communicate with one of at least two or more other computers (i.e., the backup servers) over a network, when one of the other computers (i.e., the primary server) fails. With the mechanisms of this invention, there is no need for the client to establish a new connection to a backup server when the primary server fails. The failover is preferably executed within a bridge layer between the TCP layer and the IP layer of the server's TCP/IP stack. No modifications are required to the network infrastructure, the client's TCP/IP stack, the client application or the server application. The methods support active or semi-active replication of the server application, and do not require rollback of the application during failover. The invention also provides mechanisms for bringing up new backup servers.
