摘要

A method for operating a software defined network having forwarding elements (S) and a software defined network controller (C) for controlling the forwarding elements (S) includes creating packet template information (PTI), including at least one of one or more packet templates (PT) or packet template handling instructions (FII), providing the packet template information (PTI) to one or more selected forwarding elements, the one or more selected forwarding elements being selected from the forwarding elements (5), triggering the one or more selected forwarding elements to generate an output packet (RESP) based on the packet template information (PTI), and sending, by the selected forwarding elements, the generated output packet (RESP).
