Abstract

In this paper, we seek the optimal overlay multicast performance for scalable video streaming. To adapt to layered multicast with multiple paths, a new metric layer stretch is introduced, measuring video layer's dissemination latency along the overlay. Multi-path routing, network coding based layer subscription and congest control are jointly optimized, formulating a linear programming to minimize the average layer stretch over all receivers. It not only solves the issue of inter-layer dependency of scalable video coding, but allows each receiver to determine the required video quality. Moreover, a heuristic algorithm that can be implemented in a distributed manner is provided to approximate the optimal solution. Simulation results validate the network performance of the proposed scheme.
