Privacy of users in Peer-to-peer (P2P) networks goes far beyond their current usage and is a fundamental requirement to the adoption of P2P protocols for legal usage. In a climate of cold war between P2P filesharing users and anti-piracy groups, more and more users are moving to anonymizing networks in an attempt to hide their identity. However, when not designed to protect users information, a...

We propose two new greedy algorithms to be used by software clients running the BitTorrent peer to peer protocol: a new peer selection algorithm and a new piece selection algorithm. We provide experimental results showing that the proposed algorithms are better than the ones currently in use. When used together in our experiments, the algorithms decreased the expected download time by ??% on av...

The paper reports on a detailed study of the BitTorrent content distribution system. We first present a measurement infrastructure designed to allow detailed, message-level capture and analysis of P2P traffic. An associated modeling methodology is presented as well. These tools have been used to measure and model the BitTorrent protocol, which is observed to exhibit exponential characteristics ...

This paper presents Bittella: a new social network for content distribution based on Peer-to-Peer technologies. It exploits the common interests of the users in order to create social groups based on an algorithm called Ranking Algorithm. On the other hand, Bittella is deployed over a semantic-search based and unstructured p2p network, in spite of this it uses Bittorrent-like download technique...

This paper is concerned with gifting: giving not motivated by a direct, immediate, or obvious benefit. We analyze a popular technology used for gifting: the BitTorrent file-sharing system. We determine features associated with high levels of gifting and suggest changes to the protocol and to the design of associated BitTorrent Web sites to promote it. We then extend our conclusions and suggesti...

BitTorrent, a popular Peer-to-Peer (P2P) protocol, has recently engendered considerable controversy. Many P2P applications implement a variant of the protocol due to its cost-effective scalability. However, for Internet Service Providers (ISPs) the protocol is notorious for its high network cost. To reduce these costs, ISPs have deployed network devices to detect and throttle BitTorrent traffic...

The peer-to-peer paradigm is an important alternative to the traditional client-server model in computer networks, making up a significant share of the bandwidth used globally. In client-server scenarios there usually is an external reason of why the server provides its service to the clients. But there usually is no external incentive in peer-topeer networks to share data. In fact there are tw...

Currently, BitTorrent is the most popular protocol that is widely used for P2P file sharing system. Nevertheless, BitTorrent protocol exposes some inefficient processes that are choosing neighbours and selecting pieces. These are mainly based on the knowledge of overlay topology without considering underlying internet topology that might cause of traffic problems such as the bottleneck at some ...

In the past few years numerous peer to peer file sharing, or more generally content distribution, systems have been designed, implemented, and evaluated via simulations, real world measurements, and mathematical analysis. Yet, only a few of them have stood the test of time and gained wide user acceptance. BitTorrent is not just one such system; it holds the lion’s share among them. The reasons ...

This report presents BitProbes, a system utilizing participants in peer-to-peer systems as targets for measuring the link characteristics of Internet end hosts. By connecting measurement nodes to popular swarms of the widely used peerto-peer system BitTorrent, it is showed that properties of BitTorrent make users of it well suited as targets for Internet measurements. The design and implementat...
