Abstract: This embodiments of the invention relates to a data packet forwarding unit (202) configured to forward data packets within a data transmission network on the basis of data packet forwarding rules, wherein the data transmission network comprises a control plane and a separate data plane. The data packet forwarding unit (202) comprises a storage unit (202b) configured to store at least one of data transmission profiles, wherein each data transmission profile comprises at least one data packet forwarding rule, and a processor (202a) configured to select a data transmission profile from the at least one data transmission profiles and to forward data packets within the data transmission network on the basis of the at least one data packet forwarding rule of the selected data transmission profile.
