METHODS AND APPARATUS FOR RELOCATING PACKET PROCESSING FUNCTIONS

摘要

The invention relates to a method in an arrangement of a communication network, controlling a function for processing data packets of a flow associated with a device. The method comprises determining (610) to relocate the function for processing the data packets from a source instance to a target instance for the device, controlling (620) transmission of an instruction to the source instance to relocate the function for processing the data packets to the target instance, and controlling (630) an update of a switching element in a chain of functions for processing the data packets of the flow comprising said function. The switching element affects the routing of the data packets of the flow in the chain. The switching element is updated with information related to the relocated function. The invention also relates to a method performed by the source instance and to the arrangement and the source instance.
