Abstract: Network science experimentation often requires modeling of realistic network traffic specific to the experiment environment and goals. The multi-generator (MGEN) tool, developed by the US Naval Research Laboratory (NRL), reads scripts to generate real-time traffic patterns to load the network with Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) Internet Protocol (IP) traffic. Each node generating network traffic in an experiment executes a copy of MGEN and requires a custom script to represent its traffic patterns. While this approach works well for smaller experiments, managing the scripts and generating meaningful interaction of network node traffic via the scripts becomes more cumbersome as the number of network nodes increases. This report describes the US Army Research Laboratory (ARL) Network Science Research Laboratory (NSRL) TrafficGen application, which eases the task of composing network traffic scenarios by visually representing multiple MGEN scripts simultaneously in a timeline.
