Estimating Traffic and Anomaly Maps via Network Tomography
Estimating Traffic and Anomaly Maps via Network Tomography
Mapping origin-destination (OD) network traffic is pivotal for network management and proactive security tasks. However, lack of sufficient flow-level measurements as well as potential anomalies pose major challenges towards this goal. Leveraging the spatiotemporal correlation of nominal traffic, and the sparse nature of anomalies, this paper brings forth a novel …
