Study on Network Anomaly Localization Techniques

Abstract

With the increased network scale and complexity of network topology, especially the constant variation of attacking modes, it becomes urgent to find efficient methods to localize anomalies quickly and accurately. Present studies on network performance are mostly limited to detecting anomalies, or balancing the missed rate and false alarm rate of anomaly detection. The existing small amount of localization researches are divided into two categories: localization methods based on end to end path probe and wavelet transform. This paper introduces some existing network anomaly localization methods and analyzes the performance of them. Finally, we discuss the existing technical difficulties in anomaly localization.
