Abstract :
TCRTP is a multiplexing scheme for RTP, defined by IETF, which reduces the overhead of real-time flows. This work presents a preliminary study of how the number of multiplexed flows in TCRTP can affect the Quality of Service (QoS) of VoIP in terms of R-factor. Two different buffer policies are considered. The conclusion is that multiplexing all the calls in a single TCRTP flow is not always the best solution for certain buffer policies. The reason is that higher packet sizes can increase loss probability.
