Integration of Host Position Prediction into Hierarchical Aggregation

The current RTP/RTCP [1] standard is not optimal for deployment in large-scale sessions with a single source. As the IPTV market is expected to be growing in the coming years, many universities and research laboratories are involved in optimizing for this couple of protocols. One of the most promising technologies for such purposes seems to be the Hierarchical Aggregation (HA). It optimizes transmitting of RTCP back channel and this leads to lower bandwidth requirements. This paper describes hierarchical aggregation and proposes how host position prediction can be integrated. Furthermore, this paper proposes how the host prediction can be improved using additional feedback targets and how it can be used for statistical purposes.
