Analysis of multimedia streaming service over server-based many-to-many overlay multicast

Abstract

This paper analyzed the quality of service performance of server-based overlay multicast (SOM) for real-time applications such as video conferencing. In the server-based overlay multicast, servers with high capacities play the role of routers in the application level and they form an overlay multicast network. Due to their technical difficulties such as excessive bandwidth consumption and so on, supporting them using overlay multicast has rarely been considered. First, we analyzed bandwidth consumptions and delay for server-based many-to-many overlay multicast, which were validated through simulations. Second, we propose two-layer server based overlay multicast to reduce end-to-end delay and excessive bandwidth consumption. We show the effectiveness of our scheme using NS-2 simulation.
