“…Shen (et. al) tried to tackle this problems by using the DHT network to improve the performance of the P2P live video streaming [1]. However, the availability and the low-latency problems are still the main obstacles of this work because, the stream sharing fully depends on the capacity of the users' device.…”

“…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.…”

-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.

“…Haiying Shen et al [4] propose a DHT-aided Chunk-driven Overlay (DCO). In DCO, they use a hierarchical DHT-based infrastructure and classify the peers into stable peers and common peers, where the stable peers are organized to form the DHT and other peers just choose one of stable peers to connect.…”

“…To overcome the drawbacks of current P2P streaming systems, some previous work [4], [5] has taken DHT technology into consideration. However, most of the research work does not pose any limitation on which DHT systems to be used and often utilizes some common Multi-hop DHTs, such as Chord, Pastry, etc, which are of low search efficiency and/or high-latency.…”

Abstract-DHTs have been recently used in Peer-to-Peer (P2P) live streaming systems to improve video playback continuity and data segment availability. However, existing solutions are not especially optimized for live streaming applications. There are still some challenging issues to be addressed, especially the low search efficiency for time-sensitive applications. In this paper, we propose an efficient one-hop DHT lookup framework called Streaming DHT (SDHT), dedicated to supporting media data compensation for real-time streaming applications in P2P networks. SDHT framework includes an One-hop DHT implementation solution Enhanced Event Detection and Reporting Algorithm (EDRA+) and a distributed Index Mapping and Management Mechanism (DIMM). We conduct intensive simulation experiments based on OverSim to validate the effectiveness of SDHT and evaluate its performance. Numerical results show that SDHT can significantly improve the searching efficiency and media data availability for live streaming applications, with a low overhead.Index Terms-Internet, peer-to-peer (P2P), live streaming, one-hop DHT.

“…This motivates the study of tree-structured P2P systems that are resilient to churn, which include those with backup peers [18] and those with a multiple-tree structure [3], [5], [6], [9]. On the other hand, in mesh-structured systems such as CoolSreaming [20], the delivery of a stream is realized by repeating data exchange between adjacent peers [4], [8], [11]- [13]. Since the departure of a peer can easily be recovered by adjacent peers, these mesh-structured systems are more resilient to churn than tree-structured ones, but as a side effect, it causes a high communication overhead and a relatively long delivery delay.…”

Tatsuya KOUCHI† , Nonmember and Satoshi FUJITA †a) , Member SUMMARY A key issue in Peer-to-Peer (P2P) live streaming systems is that several participant peers tend to leave within a short time period. For example, such a phenomenon is common at the half time of football games and at the end of the performance of famous artists. Such selfish behavior of the participants causes several problems in P2P networks such as the disconnection of the overlay, the departure of backup peers and the occurrence of cyclic reference to backup peers. In this paper, we propose several techniques for tree-structured P2P live streaming systems to enhance their resilience to the simultaneous departure of some participants. As the baseline of the discussion, we will focus on mTreebone which is a typical churn-resilient P2P live streaming system based on the notion of peer stability. The performance of the proposed techniques is evaluated by simulation. The simulation result indicates that even under high churn rates, the proposed techniques significantly reduce the number of attempts needed to connect to backup peers and the recovery time after a fail. key words: Peer-to-Peer live streaming, churn, resilience to simultaneous leave, cyclic reference
