Abstract

This paper presents a manageable overlay network architecture SVCP2P for live scalable media streaming. Every peer in SVCP2P periodically exchanges data availability information with one of distributed central servers which act as the centralized index for storing peer list, program list and buffer information of peers. An efficient scheduling algorithm is proposed, which achieves real-time and continuous transmission of the scalable streaming. There are three characteristics of this architecture: 1) easy management; 2) efficient to heterogeneous network because of the scalable media streaming adapting to the heterogeneous demand; and 3) robust and resilient. We have examined the SVCP2P which has been implemented based on the IP Internet over LAN, and the results demonstrate the efficiency of SVCP2P.
