CloudPP: A novel cloud-based P2P live video streaming platform with SVC technology

This paper proposes a novel Cloud-based P2P Live Video Streaming Platform (CloudPP) that uses public cloud servers as peers, to construct a robust and scalable video streaming delivery platform with Scalable Video Coding (SVC) technology. We address the problem of serving video streaming requests by using the least possible number of cloud servers. A multi-tree P2P structure with SVC is proposed and online client join/leave algorithms are also provided to efficiently organize and manage the cloud servers to serve all client requests. Compared to the other P2P architecture in Cloud, the proposed can save around 50% of the total number of cloud servers used, and improve about 90% of the benefit cost rate.
