Abstract
A method for migration of a virtual network function, VNF, from a source node to a destination node includes receiving by the destination node a snapshot of a state of the virtual network function implemented by the source node and receiving by the destination node state update elements encoding a change of the state of the virtual network function implemented by the source node caused by processing of one or more data packets received by the source node since the snapshot.
