This open conference provides a forum for operational network analysts, tool developers, researchers, and other parties interested in the analysis of large volumes of traffic to showcase the next generation of flow-based analysis techniques. Flow is an abstraction of network traffic in which packets are aggregated by common attributes over time. This year's conference will focus on the challenges of "Analysis at Scale." In large network environments, flow data helps to provide a scalable way of seeing the big picture, as well as a streamlined platform for highlighting patterns of malicious behavior over time.
