An efficient streaming method in overlay multicast networks

The predominance of unicast connectivity in the current Internet infrastructure sabotages the widespread deployment of video applications. As such overlay multicast networking has been proposed to accelerate the ubiquity of video streaming in the Internet. Based on an existing overlay multicast network architecture, this paper proposes a method which aims at improving the efficiency of the streaming scheme that is part of this architecture. Instead of sending multiple streams of the same data across the network, only the essential video signals are sent in redundancy. Evaluation of the method generates promising results in preventing loss of the essential video data in burst losses of packets.
