Abstract:
Many researches have been proposed to solve the scalability, the availability and the low-latency problems of peer-to-peer live video streaming; however, the problems are still not yet completely solved. In this paper, we propose a cloud assisted live video streaming over the distributed hash table (DHT) overlay network to tackle these problems. Our system is based on a scalable DHT network, which structures into a mesh-based overlay, to efficiently share the video stream. Moreover, cloud assist is introduced in order to maintain the availability, the low-latency and the scalability of the system. In this work, cloud server is also part of the DHT network. The role of the cloud server is to assist other nodes when the number of nodes which received video segment is less than the specific threshold. The cloud servers directly receive video segments from video server so the quality and the availability of the video segments can be guaranteed. The evaluation results show that with the help of cloud assist, the availability and the low-latency of the video segments are greatly improved if cloud has enough bandwidth.
