There is provided a method in a first device of a cellular communication system, the method comprising: acquiring a first value of a performance indicator; causing a transmission of management plane performance data to a second device of the cellular communication system, said performance data comprising said first value; acquiring a second value of the performance indicator; and preventing a transmission of the second value if the second value is substantially equal to the first value.

Management plane performance indicator transfer

A network apparatus of a communication system classifies traffic flows containing packets based on packet features. The network apparatus provides a copy of a packet contained in a traffic flow to a cluster node, and controls the cluster node to select at least one detector node based on the features of the packet and to forward said copy to the selected detector node to find out based on said copy whether the packet is malicious or not. In response to receiving from the detector node a flow indication on the traffic flow, the network apparatus controls a switch node to perform at least one flow control action on the traffic flow, the action including one or more of flow removal, flow modification and flow installation.

Anomaly detection in software defined networking

Apparatus including functionality configured to monitor said apparatus for security attacks; and a reporter configured to send data to a security node, wherein the data sent to said security node is dependent on a security level of said apparatus.
