Transmitting Hierarchical Aggregation Information Using RTCP Protocol
Radim Bürget, Dan Komosný, Milan Šimek · 2007
Summary The current state of the RFC 3550 RTP/RTCP standard is not optimal for large-scale streaming sessions employing sourcespecific multicast and is currently the subject of research in many research laboratories. The most promising optimization for the RTP/RTCP protocol seems to be hierarchical aggregation [2], [3], [5], [6], [10], [11]. However, hierarchical aggregation has not yet completely solved the problem of hierarchical structure organization. The answer can be a Tree Transmission Protocol (TTP), which seems to be flexible and powerful but quite demanding to implement. This text deals with a different approach that tries to maximally utilize the features of current standards.
