Abstract

This paper describes a new approach for analyzing large volumes of IP flow related data. One current solution for monitoring IP traffic is based on selecting a subset of flow related information that summarizes communication endpoints, volume, status and time parameters. Commonly known as NetFlow records, the recent development of a standardized protocol and data format, as well as the support from all major vendors, did make the processing, collecting and analysis of flow records possible on all available routers. However, on high traffic backbone routers, this adds to a huge quantity of data that makes its analysis difficult, both in terms of computational resources and in terms of scientific methods. We present a new approach that leverages spatial and temporal aggregated flow information. The objective is to detect traffic anomalies and to characterize network traffic. Our method is based on the use of special tree like data structures that capture both temporal and spatial aggregation and thus is computational efficient. The conceptual framework of our approach is based on the definition of appropriate similarity and distance functions for this purpose.
