Abstract :
Application layer multicast (ALM) is an effective supplement to IP multicast, but it has the potential trouble of trust on end systems. For instance, multicast receivers may cheat in order to obtain a better position in the multicast tree. Receiver cheating may transform the multicast tree, and lead to its instability. We establish the cheating model of ALM receivers and analyze the stability of ALM tree when receiver cheating occurs. Simulation results show that receiver cheating has considerably negative effects on the stability of ALM tree. This discovery brings forward an issue in ALM study, that is, we should take receiver cheating into consideration to maintain a stable ALM tree when designing ALM protocols
