In peer-to-peer video-on-demand (P2P VoD) streaming services, a video server load is reduced by peers who cache data of the viewed videos and send these data to other peers instead of the video server. Although FIFO is typically used as the caching algorithm, it is not efficient for using upload bandwidth of the peers because the peers can cache the data of unpopular videos and cannot be requested...
In this paper, we consider Peer-to-Peer Video on- Demand (P2P VoD) systems based on the Bit Torrent file sharing protocol. Since the rarest first policy adopted in the Bit Torrent protocol could not collect all pieces corresponding to a video file by their playback time, we need to develop a new piece selection rule particularly designed for P2P VoDs. In the proposed scheme, we assume the existence...
Internet-based video streaming applications is becoming more and more popular and attract millions of online viewers every day. The incredible growth of viewers, dynamics of participants, and high video quality-of-service (QoS) requirement pose scalability, availability and low-latency challenges to peer-to-peer (P2P) live video streaming systems. Tree-based systems have low-delay but are vulnerable...
In recent years, the video streaming service has become one of the most important applications. The rapid growth of users raises a big challenge to the traditional client-server VoD service. In order to provide large scale VoD service with lower server bandwidth cost, P2P technology has been introduced to VoD service. P2P based VoD service provides the same user experience as the client-server mode...
Peer-to-Peer (P2P) Video-on-Demand (VoD) systems with multiple channels are called multi-channel P2P VoD systems, which can be categorized into independent-channel P2P VoD systems and correlated-channel P2P VoD systems. Most of the existing P2P VoD systems are independent-channel P2P systems, in which the peers share resources with each other within the same channel. In this paper, we examine the...
P2P Streaming has a Real-time requirement. In the Mesh-based network, the bandwidth of fresh peers who join the network is insufficient because of lacking of data copy, and the Real-time requirement couldn't be satisfied. Therefore, the peers have to request media data from media server to satisfy the Real-time requirement which will consume a large amount of media server's bandwidth. In this paper,...
With the increasing Internet demands, there is a huge research going on in the field of Peer-to-Peer Multimedia Streaming systems. In this work, an analysis has been made on several solutions and techniques by exploring different aspects in the domain of Peer-to-Peer Multimedia Streaming. Particularly we have concentrated on the objective to guide and motivate the ongoing research in a better direction...
For poor quality of playback and low scalability in Video-on-Demand (VoD) system, it proposes combination of Content Distribution Network (CDN) and Peer-to-Peer (P2P) technologies applied in traditional C/S architecture. CDN server provides video initial data for user's fast playback and complementary streaming, P2P networks provides normally required video data downloaded in advance, the directory...
The current Internet framework is, no longer, able to support the heterogeneous networking technologies, mobile devices, increased number of users, and also the high user requirements for sophisticated services and applications. As a consequence, researchers envision the “future Internet” whereby all these issues may be effectively addressed. The future Internet architecture, amongst many components,...
Traditional client/server architecture has difficulty in coping with the significant growth of user demands due to the continuing growth of video quality and ease of producing video content. Consequently, peer-to-peer (P2P) architecture has become the most feasible solution for providing video content. In order to provide high quality video, piece scheduling, peer selection, failure recovery and a...
This paper introduces a Combinatory Optimization Problem (COP) which captures the performance in cooperation of a P2P Streaming Network, considered at the buffer level. A new family of strategies of cooperation is defined, which represents the order of query of pieces in a communication between peers. We define a measure of quality for each strategy, based on the most shocking video streaming parameters,...
Multi-hop wireless mesh networks (WMNs) are emerging as a promising technology with applications in last mile Internet access, public safety, disaster response, battlefield, etc. The unique characteristics of WMNs such as limited and dynamic bandwidth, error prone nature, interferences, and user mobility, however, pose a number of significant challenges for high quality video streaming. In this paper,...
Traditionally, a large number of dedicated media servers have been deployed to serve a large population of viewers for a single streaming event. However, maintaining media servers is not only costly but also usually requires over-provisioning due to the difficulty of predicting the peak size of an audience. Peer-to-Peer (P2P) streaming is a new approach to overcome these difficulties inherent in server-based...
To reduce the delay of video broadcast system, we analyze system-capacity in a discrete-time manner. And we propose a hybrid architecture MTreeTV which combines the use of P2P networks with dedicated streaming servers. We also evaluate the effect of the server and client parameters. Through analysis and simulation, we show that MTreeTV supports fast channel switching (<4S).1.
P2P (Peer-to-Peer) networking architectures represent scalable and cost-effective features. The media streaming technology leveraging P2P architecture is expected to be an attractive content delivery scheme and an alternative for IP multicast or content delivery systems requiring expensive network infrastructure and a large scale centralized cash storage systems. In this paper, we address the P2P...
