Tpc.exe - Third-Party Quality of Service Control Agent
This tool, which provides both command-line and GUI interfaces, enables you to work with Resource Reservation Protocol (RSVP), a Quality of Service (QoS) feature. You can use Tpc to test RSVP and to set up RSVP sessions on behalf of applications that are not QoS-aware. See the Internet Engineering Task Force's RSVP Request For Comment for details on RSVP parameters.
