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.
