A Practical Semantic Reliable Multicast Architecture

IP Multicast has been developed in the past few years to support multi-point communication in Internet. However, it is still hard for protocol designers to tackle the intrinsic heterogeneity of networks and end-systems. Moreover, in practical, current Internet is not fully multicast-enabled. In this paper, we present a practical semantic reliable multicast (PSRM) architecture for current Internet-based applications. It takes the notion of “semantic” reliability and leverages application-specific semantics to transcode content during delivery. By combining multicast and unicast, PSRM becomes much more practical in the current Internet infrastructure, and benefits from IP multicast to maximum extent.
