The Drexel Network Toolkit is a software package for testing various approaches to QoS on IP-based networks. It uses Linux and DiffServ packet-marking primitives to classify and prioritize packets. DNT was used in a project to evaluate satellite based IP delivery for multimedia applications in telemedicine and telemaintenance.
