Fine-grain layered multicast based on hierarchical bandwidth inference congestion control

The paper presents an approach to facilitate bandwidth inference congestion (BIC) control in a fine-grain layered multicast for multimedia delivery. One-way delay trend detection has been shown to be effective in explicitly or implicitly estimating the end-to-end available bandwidth. By using a hierarchical layered probe in combination with the delay trend detection scheme, we propose a congestion control protocol for fine-grain layered multicast of 3D wavelet based scalable video streaming over heterogeneous networks.
