| Description
| - Článek se zabývá typem multicastu, kde je pouze jeden zdroj a více příjemců. Tato struktura se stává populární při nasazování nových služeb, jako je například vysílání IPTV. Multicast je často postaven na protokolu RTP/RTCP (Real Time Protocol/Real Time Control Protocol). Protokol RTCP slouží k přenosu signalizace, kterou je nutno přenášet i od příjemců ke zdroji. Problémem multicastu s jedním zdrojem je, že nelze tuto signalizace přenášet po multicastovém spojení. Proto se používají unicastová spojení od příjemců ke zdroji. V tomto článku jsou popsány možnosti přenosu této signalizace pomocí sdružování příjemců do skupin. Skupiny jsou definovány podle kvality přenosu na straně příjemců (např. ztrátovost paketů a variace zpoždění). (cs)
- The recent deployment of IP-based TV and radio distributions requires one-to-many multicast instead of the traditional many-to-many data distribution. These large multimedia sessions usually rely on the real time protocol (RTP) and the real time control protocol (RTCP). Although one-to-many multicast offers the required communication, it does not support the multicast feedback channel for carrying the RTCP control messages. Therefore, unicast feedback channels from session members to the source are used to carry these messages. In this paper, we introduce subgroup feedback scenarios for source-specific multicast, which is built on the one-to-many philosophy. Our extensions are based on the subgroup feedback framework standardized in the IETF. We outline a possible implementation of the subgroup feedback using the receiver summary information (RSI) packet. A theoretical RSI packet rate analysis is also presented in the paper.
