| Abstract: | The service bandwidth optimization problem for multicast video-on-demand systems with early service merging is investigated, and a series of on-line algorithms based on recursive patching are proposed in this research. We adopt a simple fixed-threshold starting rule and introduce a control window to regulate the degree of service merging. Our resultsindicate that the cost-aware recursive patching (CARP) with a carefully chosen control window can significantly reduce the service bandwidth consumption. We also study the promoting rule and the limited client buffer effect for practical recursive patching algorithms. Experimental result shows that the proposed recursive patching schemes outperform graceful patching with a wide margin even with a very small client buffer size. | ||
