“…The disadvantage of this approach is that the feedback resolution requires multiple round trip times over the high latency satellite channel. In Reference [65], the authors propose forming receiver clusters based on their spatial correlations, e.g. rain fall precipitation data, which is a prime factor that degrades service quality.…”

SUMMARYIn a wide variety of broadband applications, there is a need to distribute information to a potentially large number of receiver sites that are widely dispersed from each other. Communication satellites are a natural technology option and are extremely well suited for carrying such services because of the inherent broadcast capability of the satellite channel. Despite the potential of satellite multicast, there exists little support for multicast services over satellite networks. Although several multicast protocols have been proposed for use over the Internet, they are not optimized for satellite networks. One of the key multicast components that is affected when satellite networks are involved in the communication is the transport layer. In this paper, we attempt to provide an overview of the design space and the ways in which the network deployment and application requirements affect the solution space for transport layer schemes in a satellite environment. We also highlight some of the issues that are critical in the development of next generation satellite multicast services.

“…The algorithm immediately identifies the worst-performing user in the serviced area and designates him as the area representative (AR) based on the fact that the AR transmits FBMs faster than the other users, thus suppressing their feedback. In [23], a cluster-based algorithm is proposed where all Earth terminals belonging to the same cluster use a distinct return channel. The return channel may be reused by other clusters due to the low probability of the event that distant receivers send FBMs simultaneously.…”

Feedback implosion is a major problem limiting scalability in multicast satellite networks that arises when a large number of users transmit their feedback messages (FBMs) through the uplink channel, occupying a significant portion of system resources. This paper investigates how suppression of FBMs may be achieved through a novel feedback suppression scheme in which each user unilaterally decides whether to send a FBM or not. The users decisions are modeled applying game theory with inaccurate information. For this problem, the Bayesian equilibrium for the two and N-player game is investigated. It is proved that the feedback suppression game has a unique Bayesian equilibrium point. Then, based on appropriate numerical and simulation results, it is demonstrated that the proposed scheme avoids feedback implosion while at the same time it keeps feedback latency at very low levels. Finally, it is shown that the proposed scheme exhibits a significant performance improvement compared to existing exponential timer-based schemes.Index Terms-Bayesian equilibrium, feedback suppression, game theory, IP multicast, multicast satellite systems, reliable multicast, satellite networks.

“…However, the main disadvantage of this method is that the feedback suppression algorithm assumes deterministic timeouts requiring multiple RTTs over the high delay satellite channel. Furthermore in [7], a cluster-based algorithm is proposed, where Earth terminals within the same cluster use distinct return channels that may be reused by other clusters due to the low probability that distant receivers send FBMs simultaneously. Another feedback suppression algorithm [8] allocates receivers to return channels trying to minimize the total number of return channels used for feedback transmission.…”

SUMMARYThe major problem limiting the scalability of large-scale multicast satellite networks is feedback implosion that arises whenever a large number of users simultaneously transmit feedback messages (FBMs) through the network, thus occupying a significant portion of satellite system resources. In satellite networks operating above 10 GHz, attenuation due to rain constitutes the dominant fading mechanism deteriorating the quality of service. In this paper, a novel scheme for providing large-scale reliable multicast services through a star-based geostationary satellite topology is presented incorporating accurate channel modeling of the propagation phenomena. The new protocol is based on the selection of an area representative that provides quick FBMs aiming at suppressing FBMs originating from the rest of the network users. The scheme provides a timely reaction to changes of either the channel conditions or the network topology by properly updating the selection of representatives. Through appropriate simulations, comparisons and examples it is demonstrated that the new approach suppresses FBMs very effectively.
