Growth in large-scale experiments using high capacity reliable networking as part of their design is creating a need for better monitoring and analysis of observed traffic. Network providers need intelligent solutions that can help quickly identify and understand anomalous behaviors at the network edge, allowing reactions to unexpected traffic or attacks on facilities and their peerings. However, due to lack of labeled data in network traffic analysis and user diversity, we introduce novel methods that process very large network datasets quickly for outlier identification. In this paper, we leverage artificial intelligence (AI), network research, and edge computing to collect and train unsupervised classification algorithms using streaming data pipelines from multiple months of network flow records. Once trained, individual classifiers quickly observe and flag alerts in hourly behaviors. Our work describes building the data pipeline as well as addressing issues of false positives and workflow integration.
