Abstract: This paper summarizes the mechanism and realization methods of RSVP. We also construct a VoD experiment system based onRSVP and analyze its performance compared with that based on TCP and UDP. The result indicates RSVP can dramatically approve real-timetraffic QoS in circumstance of congestion.
