Abstract: This paper analyzes the causes of the insufficient QoS of reaLtime applications under the current Internet service model, as wellas, presents and compares some alternahve strategies to improve QoS of real-time aPplications. Then we focus on analyzing the RSVPprotocol and its applicability in real-time applications. Furthermore, the scalability problems of RSVP are also discussed and possibleapproaches to solve those problems are studied.
