Reliable Multicasting via Satellite: Delay Considerations

Abstract

Many different reliable multicast protocols have been proposed and analyzed in the current literature. Since satellites are naturally a broadcast medium, multicast communications have the potential to greatly benefit from their wide-scale deployment. The performance of reliable multicast protocols needs to be studied and become better understood over networks including satellite links. Most of the analysis performed on these protocols has dealt with bandwidth usage, buffer requirements, and processing delay. Very few studies address the transmission delay incurred from using reliable multicast protocols. Hybrid error control protocols have been studied in terms of bandwidth and delay. The effects of different estimation schemes coupled with autoparity usage are investigated and results are compared. Simple adaptive mechanisms used with a local recovery scheme are found to offer the best overall results in terms of reducing recovery latency and satellite bandwidth usage.
