Abstract: The invention concerns a method for migration of a virtual network function (1), VNF, from a source node (2) to a destination node (3). The method comprises receiving by the destination node (3) a snapshot of a state of the virtual network function (1) implemented by the source node (2) and receiving (9) by the destination node (3) state update elements encoding (17) a change of the state of the virtual network function (1) implemented by the source node (2) caused by processing of one or more data packets (5) received by the source node (2) since the snapshot. The invention concerns further the source node (2), the destination node (3) and a software program product adapted to implement the method.
