Experiments on diverse topics such as network measurement, management and security are routinely conducted using empirical network flow export traces. However, the availability of such traces from operational networks is limited and frequently comes with significant restrictions. Furthermore, empirical traces typically lack critical meta-data (e.g., labeled anomalies) which reduce their utility in certain applications.

In this talk, I’ll describe a first-of-its-kind tool called fs that is designed to automatically generate representative network flow records as well as basic SNMP -like router interface counts. fs efficiently generates measurements for a target network topology with specified traffic characteristics. The resulting records for each router in the topology have byte, packet and flow characteristics that are representative of what would be seen in a live network.
