Content Distribution in P2P Systems
نویسندگان
چکیده
The report provides a literature review of the state-of-the-art for content distribution. The report’s contributions are of threefold. First, it gives more insight into traditional Content Distribution Networks (CDN), their requirements and open issues. Second, it discusses Peer-to-Peer (P2P) systems as a cheap and scalable alternative for CDN and extracts their design challenges. Finally, it evaluates the existing P2P systems dedicated for content distribution according to the identified requirements and challenges.

Nous apportons trois contributions principales. En premier lieu, nous donnons un aperçu global sur les réseaux de distribution de contenu, leurs exigences et leurs problèmes. En second lieu, nous étudions les systèmes P2P en tant qu’alternative efficace aux CDNs et nous identifions leurs défis. Enfin, nous évaluons les systèmes P2P existants qui sont conçus pour la distribution de contenu.

A Case for P2P Delivery of Paid Content
P2P file sharing provides a powerful content distribution model by leveraging users’ computing and bandwidth resources. However, companies have been reluctant to rely on P2P systems for paid content distribution due to their inability to limit the exploitation of these systems for free file sharing. We present TP2, a system that combines the more cost-effective and scalable distribution capabil...
متن کاملFramework for preserving security and privacy in peer-to-peer content distribution systems
The use of peer-to-peer (P2P) networks for multimedia distribution has spread out globally in recent years. The mass popularity is primarily driven by efficient distribution of content, also giving rise to piracy. An end user (buyer) of a P2P content distribution system does not want to reveal his/her identity during a transaction with a content owner (merchant), whereas the merchant does not w...
متن کاملUsing P2P Techniques for Content Distribution Internetworking: A Research Proposal
In this paper we discuss the use of algorithms and techniques, currently deployed in Peer-to-Peer (P2P) systems, in the design of Content Distribution Internetworks (CDIs). Specifically, we propose a CDI design approach that addresses issues of request routing, content delivery, and replication, based on P2P techniques.
متن کاملDiffusion Models for Peer-to-Peer (P2P) Media Distribution: On the Impact of Decentralized, Constrained Supply
In Peer-to-Peer (P2P) media distribution, users obtain content from other users who already have it. This form of decentralized product distribution demonstrates several unique features. Only a small fraction of users in the network are queried when a potential adopter seeks a file and many of these users may even free-ride i.e. not distribute the content to others. As a result, generated deman...
متن کاملPeer to Peer Edge Caches Should be Free
Bulk-data peer to peer systems have been promoted as reducing the cost of content distribution. Unfortunately, this isn’t generally true. Rather, bulk-data P2P shifts the costs of delivery from the content provider to the ISPs or content recipients. A very simple economic model of content delivery shows how this occurs and that, under some conditions, P2P can grossly magnify costs. Even with lo...
