The Multi-Generator (MGEN) is open source software by the Naval Research Laboratory (NRL) PROTocol Engineering Advanced Networking (PROTEAN) Research Group. MGEN provides the ability to perform IP network performance tests and measurements using UDP/IP traffic (TCP is currently being developed). The toolset generates real-time traffic patterns so that the network can be loaded in a variety of ways. The generated traffic can also be received and logged for analyses. Script files are used to drive the generated loading patterns over the course of time. These script files can be used to emulate the traffic patterns of unicast and/or multicast UDP/IP applications. The receive portion of this tool set can be scripted to dynamically join and leave IP multicast groups. MGEN log data can be used to calculate performance statistics on throughput, packet loss rates, communication delay, and more.
