On Improving the Throughput of Media Delivery Applications in Heterogeneous Overlay Network

Overview Overlay multicast is becoming increasingly popular for multimedia delivery over Internet. The available bandwidths between sender and different receivers are generally heterogeneous. This paper proposes a scheme to improve the throughput of a media delivery session with heterogeneous receivers by organizing the receivers into layered data distribution meshes and sending substreams to each mesh using layered coding. The solution utilizes alternative paths and network coding in each mesh. The paper first formulates the problem into a mathematical programming, whose optimal solution requires global information. It therefore presents a distributed heuristic algorithm. The heuristic progressively organizes the receivers into layered meshes. Each receiver can subscribe to a proper number of meshes to maximize its throughput by fully utilizing its available bandwidth.
