摘要

Method and device for operating a network component (104) and a control entity (102) in a software defined networking communication infrastructure (100), the software defined networking communication infrastructure (100) depending on at least one trigger signal from an operation according to a first strategy for Forwarding of time-critical data streams in network components (104) of the communication infrastructure (100) is switched to an operation according to a second strategy for forwarding time-critical data streams in network components, wherein the at least one trigger signal in an operation according to the first strategy from a control entity (102) a unicast message or in a broadcast message is received, with the network component (104) checking whether the second strategy is implemented or can be implemented or not, the network component (104) depending on a result of the check, in In response to the trigger message, a response message is sent to the control entity (102) that includes information about whether the second strategy is implemented or can be implemented or not, and the control entity (102) checks whether at least one of the plurality of network components (104) a response message is received in response to the sending of the trigger message, which includes information about whether the second strategy can be implemented or not, and an abort message from the control entity (102) in particular in a plurality of unicast messages or in a broadcast message is sent if the second strategy cannot be implemented by at least one of the plurality of network components (104), or if at least one of the plurality of network components (104) up to a predetermined point in time after sending the trigger message, no information is received about whether the second strategy can be implemented or Not.
