A hybrid CDN/Viewer-to-Viewer (V2V) architecture is an attractive solution for HTTP (HLS) and MPEG-DASHbased live streaming providers. It combines a traditional CDN with a V2V overlay for exchanging video fragments, reducing the cost of the CDN while maintaining the quality of experience. This work explores machine learning models to address the key challenge of neighbor selection. Our goal is to predict the connection quality between two arbitrary viewers using features such as locality, access providers, operating systems, past CDN, and V2V throughput. The proposed solutions are validated using an A/B testing approach on our production system, demonstrating a significant improvement in key system metrics compared to the traditional locality-based methods. We observe 17% higher V2V throughput, 26% lower delay, 37% fewer lost chunks, 39% fewer re-buffering, and 20% fewer quality switches.

“…Many existing works have been studying on P2P live video streaming; however, most of those works focused on tree-based [2][3][4], mesh-based [5][6][7], and hybrid structure [8][9][10]. Only a few works have focused on using DHT [1] and cloud assist in P2P live video streaming [11][12][13].…”

-Many works have attempted to solve the scalability, the availability, and the low-latency problems of peer-to-peer (P2P) live video streaming; yet, the problems still remain. While tree-based systems are vulnerable to churn, the mesh-based systems suffer from high delay and overhead. The DHT-aided chunk-driven overlay (DCO) [1] tried to tackle these problems by using the distributed hash table (DHT), which structures into a mesh-based overlay to efficiently share the video segment. However, DCO fully depends on the capacity of the users' device which is small and unstable, i.e., the users' device may leave and join the network anytime, and the video server's bandwidth can be insufficient when the number of users joining the network suddenly increases. Therefore, cloud assist is introduced to overcome those problems. Cloud assist can be used to enhance the availability, the low-latency, and the scalability of the system. In this paper, the DHT is used to maintain the location of the streaming segments in a distributed manner, and the cloud server is used to assist other peers when the bandwidth which required for sharing the video segment is insufficient. The simulation results show that by using the threshold and cloud assist, the availability and the low-latency of the video segments, and the scalability of the network are greatly improved.

“…HLPSP consider the upload bandwidth of peers for overlay creation, other crucial factors like the stability of each peer, geographical location are not considered. A new hybrid overlay creation is discussed in our previous work [29], which consider all different crucial factors which are discussed above for overlay construction. This approach is a hybrid overlay combination of both tree and mesh overlay.…”

With a sudden surge in demand for live video streaming using peer to peer (P2P) network, there has been a rise of traffic in media transmission applications that employ this P2P approach. P2P is a decentralized media communication method which is more cost effective, and scalable. However, the traditional peer to peer network architecture has several limitations, and overlay construction is one of them. The two different unstructured overlay approaches like tree and mesh have already been discussed. This paper gives a detailed comparison of various overlay approaches in P2P networks. We have also proposed and implemented a utilization based hybrid overlay approach for the P2P network. The two crucial parameters which are primarily considered while overlay construction is: peer upload bandwidth and peer resource utilization. For the purpose of verifying our approach, we have done a comparative analysis of the proposed utilization based approach with the popular DenaCast approach. The different QoS parameters like start-up delay, playback delay, end to end delay, frame loss ratio are used for verifying our approach. The simulation results presented in this paper provide better network performance and quality of video at receiver side.
