MINT allows a network engineer to easly set up multicast sources and recievers to test a multicast network's ability to send and recieve packets.
With the help of the open source community MINT will evolve into a full featured packet generation utility. It currently generated UDP multicast packets. It will eventually support packet generation for IPv4 unicast TCP and UDP packets with QoS tags, IPv4 multicast, and IPv4 multicast PGM packets as well making it a complete replacement for TTCP with many new options.
