Abstract
HA peers can include networking devices that have data planes and control planes that configure the data plane to use status data in a memory for processing network packets of network flows. The HA peers synchronize the status data such that one peer can take over when another fails. When a HA peer is brought up, data plane syncing synchronizes data for new network flows but not existing network flows. A first bulk sync operation synchronizes data for existing flows but not for new flows. A second bulk sync operation can synchronize the data for flows that changed state during the first bulk sync operation. Data plane syncing can sync data for all flows after the first bulk sync operation.
