Many emerging continuous media applications can tolerate some degree of both packet loss and delay. Retransmission- based packet loss recovery protocols, which reduce packet loss at the expense of playout delay, appear promising for this class of applications. We describe a point-to-point implementation of a retransmission-based error recovery protocol. The implementation helps identify a number of problems that exist when extending the approach to multicast distribution. To study these problems, we introduce and analyze a model of multicast network packet loss. We show that one possible solution to the realization of bandwidth- efficient error recovery protocols lies with emerging active network technology.
