We introduce the PlanetP system, which explores the construction of a content addressable publish/subscribe service using gossiping between peers of an unstructured peer-to-peer (P2P) community. Unlike many recent P2P systems that have focused on enabling very large-scale name-based object location, PlanetP does not build and maintain a sophisticated(More)
We consider the problem of content search and retrieval in peer-to-peer (P2P) communities. P2P computing is a potentially powerful model for information sharing between ad hoc groups of users because of its low cost of entry and natural model for resource scaling with community size. As P2P communities grow in size, however, locating information distributed(More)
We consider the problem of increasing the availability of shared data in peer-to-peer (P2P) systems so that users can access any content, regardless of the current subset of online peers. In particular, we seek to conservatively estimate the amount of excess storage required to achieve a practical availability of 99.9% by studying a decentralized algorithm(More)
We consider the use of cooperative caching to manage the memories of cluster-based servers. Over the last several years, a number of researchers have proposed locality-conscious servers that implement content-aware request distribution to address this problem [2, 17, 4, 5, 6]. During this development, it has become conventional wisdom that cooperative(More)
Social networks offering unprecedented content sharing are rapidly developing over the Internet. Unfortunately, it is often difficult to both locate and manage content in these networks, particularly when they are implemented on current peer-to-peer technologies. In this paper, we describe Wayfinder, a peer-to-peer file system that targets the needs of(More)
We consider the problem of ensuring high data availability in federated content sharing systems. Ideally, such a system would provide high data availability in a device transparent manner so that users are not faced with the time-consuming and error-prone task of managing data replicas across the constituent devices of the system. We propose a novel unified(More)
