Abstract: An embodiment first network node has a data flow table identifying forwarding rules to be applied to incoming data packets. The first network node is configured to allow for manipulation of the data flow table via control messages received via a control connection to a controller. The first network node is further configured to determine an occurrence of a network event or compliance with a condition specified by the controller. The first network node is further configured: to establish a control connection to a second network node in case that the network event occurs or the condition is met and to exchange control messages with the second network node via the control connection.

Abstract: The application provides a switch device and a software defined network (SDN) controller. The switch device includes a storage unit configured to store control flow entries, each control flow entry comprises at least one service field associated with at least one processing action, a receiver configured to receive a data plane packet, and a transmitter configured to transmit, to the SDN controller, a packet-in message, and a processor configured to determine whether at least one information field of the data plane packet or of the packet-in message matches the at least one service field of a control flow entry, and instruct the transmitter to transmit the packet-in message according to the processing action associated with the matched service field, if the at least one information field matches the at least one service field.
