Abstract: It may be that data collected, and retrieved, for a model training is not sufficient, and hence additional data may be needed. When it is determined that additional data is needed to complement the data retrieved, synthetic data is generated, and training data is obtained by combining the synthetic data with the data retrieved, and the model training is performed. A ratio of the synthetic data to the training data is determined and the ratio is indicated in a response to a request that caused the model to be trained.

Abstract: 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.

Abstract: In accordance with an example embodiment of the present disclosure Ethernet communication over IP transport is enabled. The following is performed: Ethernet communication for transmitting and receiving Ethernet frames; IP communication for transmitting and receiving IP data packets over a cellular network; transforming Ethernet frames to IP data packets and vice versa for enabling Ethernet communication over IP transport; and maintaining a header transformation table between Ethernet and IP traffic flows. The transforming comprises using the header transformation table and performing header transformation by removing Ethernet headers from received Ethernet frames and including Ethernet payload in IP data packets, and by reconstructing Ethernet headers for received IP data packets for transmission of payload from the IP data packets in Ethernet frames, wherein the transforming comprises using IPv6 headers of IP data packets to carry dynamic information from the removed Ethernet headers.

Abstract: Two competing machine learning based models, a first model for generating synthetic data, and a second model for classifying input data to synthetic data and real data, are trained by training the second model until its accuracy meets a preset rule, and then the first model is trained. After training the first model, training of models is repeated until an end criterium is met.
