For the multimedia streaming applications to apply RTP/RTCP, two significant factors are the performance of long periodic control with RTCP, and the friendliness to TCP on the rate adjustment. To satisfy these two criteria, this paper proposes a rate estimation scheme based on the packets loss ratio and jitter ratio sampling at the RTP/RTCP-like receiver and adopting the time-based TCP model. The 'Time-based' model is a rate equation of the variables of time, while the existing model, named 'Packet-based', is another equation of the variables of packet counting. The meaning of rate estimation is that for one connection of a particular sending rate, the receiver can closely estimate the average transmission rate of other TCP flows in competition. The simulation results show that our rate estimation approach conducts good estimation, and can be the basis of rate adjustment and congestion control.
