by their ability to adapt to failures and accommodate transient populations of nodes while maintaining acceptable connectivity and performance. Content distribution is an important peer-to-peer application on the Internet that has received considerable research attention. Content distribution applications

Peer-to-peer (P2P) file sharing accounts for an astonishing volume of current Internet tra#c. 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

The popularity of peer-to-peer multimedia file sharing applications such as Gnutella and Napster has created a flurry of recent research activity into peer-to-peer architectures. We believe that the proper evaluation of a peer-to-peer system must take into account the characteristics of the peers

directions; and 3) robust and resilient, as the partnerships enable adaptive and quick switching among multi-suppliers. We show through analysis that DONet is scalable with bounded delay. We also address a set of practical challenges for realizing DONet, and propose an efficient member- and partnership

This paper explores requirements for efficient pre-seeding of videoon-demand (VoD) movie data onto numerous customer set-top boxes in a cable ISP environment. The pre-seeded content will then be distributed to other set-top boxes in the same cable community using a peer-to-peer (P2P) network

Peer-to-peer (P2P) online communities are commonly perceived as an environment offering both opportunities and threats. One way to

Abstract — Over the Internet today, computing and communications environments are significantly more complex and chaotic than classical distributed systems, lacking any centralized organization or hierarchical control. There has been much interest in emerging Peer-to-Peer (P2P) network overlays

The throughput of Peer-to-Peer (P2P) Video-on-Demand (VoD) systems is typically capped by the users ’ aggregate upload bandwidth [1]. The drastic increase in the popularity of VoD and the demand of higher quality content has thus placed substantial burden on the content servers. We investigate a

This paper provides a brief introduction to peer-to-peer (P2P) systems. Basic definitions and character-istics of P2P systems are described in Section 1. A comparison of a two related paradigms: P2P and Grid computing is also given. Section 2 classifies P2P substrates into two categories
