Peer-to-peer systems have recently received tremendous amount of popularity in both research and commercial endeavors. This paper argues for the systematic exploration of a hybrid of centralized and peer-to-peer system design. We give an example application of peer-to-peer architecture to an inherently centralized service and show how this application raises an interesting research question in the...
The continuous growth in both commercial and public network traffic with various quality-of-service (QoS) requirements is calling for better service than the Internet's best effort mechanism. One of the challenging issues is to predict the overall behavior of aggregate network traffic. While network traffic characterization has been studied extensively due to its importance in network scheduling and...
In this paper, we firstly analyze the mechanism of PeerCast as a P2P live streaming steaming solution. An then, based on the shortcoming analysis of tree-based PeerCast, we propose a improved tree-mesh-hybrid scheme-MultiPeerCast, including Multi-thread media transmission, multiple-to-one overlay network reconstruct, optimized buffer design, media retrieving style changing from push mode to pull mode...
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...
Many people associate peer-to-peer technology with file-sharing applications such as BitTorrent, Gnutella, Kazaa, and Napster and with concerns about the unauthorized, free distribution of video, audio, and other copyrighted content. These concerns have led the entertainment industry to crack down on P2P systems. For example, the US Recording Industry Association of America (RIAA) has taken numerous...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
