Abstract :
In this paper, we propose RALF, a new FEC-based error control protocol for layered multicast video. RALF embodies two design principles: decoupling transport layer error control from upper layer mechanisms and decoupling error control and congestion control at the transport layer. RALF works with our previously proposed protocol RALM - a layered multicast congestion control protocol with router assistance. RALF provides tunable error control services for upper layers. It requires no additional complexities in the network beyond those for RALM. Its performance is evaluated through simulations in NS2.
