DUALCAST: a scheme for reliable multicasting

Abstract

With the rapid deployment of high speed networks and the increased use of applications that blend voice, data, and video traffic, protocols have to be looked at anew. The problem of trying to conserve bandwidth is being replaced by the problems of overcoming latency and processing bottlenecks. In this paper, we introduce the conflicting demands in implementing reliable multicast and then present a new heuristic that balances the tradeoffs by using redundancy while not loading the network excessively.<>
