Peer-to-peer (P2P) file sharing accounts for an astonishing volume of current Internet traffic. This paper probes deeply into modern P2P file sharing systems and the forces that drive them. By doing so, we seek to increase our understanding of P2P file sharing workloads and their implications for future multimedia workloads. Our research uses a three-tiered(More)
In the span of only a few years, the Internet has experienced an astronomical increase in the use of specialized content delivery systems, such as content delivery networks and peer-to-peer file sharing systems. Therefore, an understanding of content delivery on the lnternet now requires a detailed understanding of how these systems are used in(More)
The availability of a P2P service is a function of the individual peers' availabilities, and it is often desirable to estimate how available a particular P2P service will be given the availability of its peers. Prior work in this area has widely used the fraction of time the average peer is available as the basis for this estimate. We show here that this(More)
We examine the performance dynamics of a generic media delivery service, in which a single provider distributes to a set of peers using a BitTorrent-like protocol. Previous studies of BitTorrent have examined its performance in delivering single objects; here we discuss the dynamics of distributing a population of objects. Specifically, we assume that peers(More)
The Peer-to-peer (P2P) computing has been one of the emerging technologies, particularly contributing in distributed file sharing. Experimental studies show that for a file download, network congestion or service capacity fluctuation takes minutes to several hours. For a P2P n/w one of the fundamental performance metrics is the average download time. The(More)
