This paper proposes a network anomaly detection method based on catastrophe theory. The network anomaly detection model based on catastrophe theory is constructed by utilizing the catastrophe characters of the cusp catastrophe model in catastrophe theory and analyzing the properties of network data included normal and abnormal data. The simulation demonstrated that with the anomaly detection algorithm, this model could detect the network anomaly not only timely, but also detect precisely.
This paper proposes a three-layer service model in optical networks. It utilizes diversity design and service shift
mechanisms. Both the analysis and simulation results demonstrate this model can effectively promote the survivability of
IP networks.
