| Abstract: | Video on demand services require video multicasting protocols to provide efficient and reliable performances over various client request rates. While reactive protocols perform very wellwhen video demand is low, well-known reactive protocols can'teffectively handle these video in situation of high demand.In this work we have developed an efficient video multicasting protocol, the feedback based multicasting protocol, that requireslower bandwidth to multicast a video at any access rate. The proposed protocol uses an on-line stream merging scheme requiring lower merging costs than other previous schemes.We have provided both analysis and simulation to show theperformance gain over previous protocols. From an analyticalmethod, we found the expected service bandwidth of the feedback based multicasting protocol(FMP) is less than that of previous reactive protocols. Furthermore, the FMP shows similar bandwidth requirement to one of the best existing proactive protocols at high client request rates. | ||
