  • Method for checkpointing and reconstructing separated but interrelated data
    Patent number: 7814309
    Abstract: A method is disclosed whereby separate but interrelated data is checkpointed and reconstructed within a router. In one embodiment, each connection is checkpointed with a unique connection identifier, and critical data is stored by a firewall application in a checkpoint server provided within a router. When an application module within the firewall crashes, the firewall and associated modules may recover and restore the data from the checkpoint server by re-assembling the data according the unique connection identifier, thus recovering the connections through the router without interruption.
