Abstract
Methods and systems for managing a connection in an internet protocol virtual server (IPVS). At least a portion of checkpoint data is transmitted by a first node of the IPVS to a load balancer of the IPVS. The checkpoint data includes information for restoring an active connection of the first node and also information representing the current state of the active connection. The load balancer stores the checkpoint data in association with connection data for the connection. The first node terminates the connection. The load balancer updates the connection data with information about a second node of the IPVS. The checkpoint data is transmitted to the second node. Incoming data packets for the connection are then forwarded to the second node, in accordance with the updated connection data.
