Disabling Traffic Control
Traffic control is invoked by default, and is done so immediately upon the receipt of a sending FLOWSPEC. Application programmers, however, can disable traffic control by using the SERVICE_NO_TRAFFIC_CONTROL service type. When the SERVICE_NO_TRAFFIC_CONTROL service type is used, traffic control is not invoked on the specified flow regardless of RSVP signaling. If quality of service is reset (modified) without the SERVICE_NO_TRAFFIC_CONTROL flag, traffic control is invoked.
RSVP signaling is not supported on Windows XP or later versions of Windows.
