Transport layer statistical multicast based on the XTP bucket algorithm

摘要: Multicast or point-to-multipoint transmission is becoming a major issue for supporting distributed multimedia applications. In this paper, we analyze the service provided by theXtp reliable multicast. We discover several problems and drawbacks, such as multiple retransmission of same data packets protocol inefficiency when performing with large group size non-broadcast networks. To overcome some these problems, introduce new constraints at sender side to prevent any unnecessary retransmissions. semantic calledstatistical cope while keeping high level reliability (related error recovery issues). The quality modified assessed simulation experiments two different network environments :Fddi andAtm. show that almost binary, i.e. all unreliable all. If parameters are correctly sized, can expect get an using statistical benefit low overhead. now working on version proposed specifically adressAtm based
