Abstract
A method and a control node (300) for establishing network functions for processing data packets of a data flow from a delivering node (306) to a receiving node (308) over a communication network (302). The control node identifies (3:2) flow characteristics relating to the data flow and determines (3:3) a succession of network functions (304) in the network for processing the data packets, based on the identified flow characteristics. The network functions (304) are then instructed (3:4a-c) to forward the data packets in the data flow according to the determined succession. The sequence of network functions specifies a service chain. The controller uses OpenFlow. Network functions are dynamically relocated based on network conditions.
