Abstract

Live media streaming applications are increasing dramatically on the Internet such as IPTV, distance learning, video conference etc. Meanwhile, layered transmission is a promising solution to video streaming over the heterogeneous Internet. This paper presents LSONet, which leverages the advances in both the field of media compression, i.e., layered video coding, and the field of networking, i.e., application-level overlay networking. The purposes are, respectively, to obey the delay requirement, to improve bandwidth efficiency and to adapt to network jitter. The proposed system is completely self-organizing, and it can adapt to network dynamics in a fully distributed fashion. Extensive simulations have been performed. The results show that the system outperforms previous scheme in resource utilization and more robust and resilient for network fluctuation, which demonstrate that the proposed architecture and the associated protocol are well-suited for quality adaptive live streaming applications
