As TCP/IP networks develop, various type of applications or services are appearing.Especially, many people want to use real time multicast applications over TCP/IP networks like a TV conference system.Most of the current TCP/IP networks, however, still do not support QoS guarantees using RSVP, so that they provide only a best-effort service.Therefore, such real time applications must control data transmitting rate by the network or receiver's condition.However, it is difficult to control data rate over a multicast session, since every receiver on a multicast network does not necessarily have the same environment.To solve this problem, the authors proposed a locally adaptive control intermediate system.This paper describes a rate-adaptive real-time multicast system with locally adaptive packet flow control.
