  • topic 7 peer to peer computing
    International Conference on Parallel Processing, 2007
    Co-Authors: Alberto Montresor, Fabrice Le Fessant, Dick Epema, Spyros Voulgaris
    Abstract:

    Distributed systems have experienced a shift of scale in the past few years. This evolution has generated an interest in Peer-to-Peer systems and resulted in much interesting work. Peer-to-Peer systems are characterized by their potential to scale due to their fully decentralized nature. They are self-organizing, adapting automatically to peer arrivals and departures, and are highly resilient to failures. They rely on a symmetric communication model where peers act both as servers and clients. As the Peer-to-Peer concepts and Technologies become more mature, many distributed services and applications relying on this model are envisaged in the context of large-scale distributed and parallel systems. This topic examines Peer-to-Peer Technologies, applications, and systems, and also identifies key research issues and challenges. Twenty-six papers were submitted to the track and we accepted six. We organized two sessions, the first devoted to the problem of query management in structured and unstructured overlay networks, the second containing a broader selection of topics.

  • osprey peer to peer enabled content distribution
    ACM IEEE Joint Conference on Digital Libraries, 2005
    Co-Authors: John Reuning, Paul Jones
    Abstract:

    As the size of data and files increases, digital repositories face a growing problem in content distribution. High quality multimedia and research data sets can range from 100's of megabytes to over a terabyte. Web-based digital repositories may exper ience a substantial increase in operating and bandwidth costs when providing materials to the public. Peer-to-Peer networks are sometimes suggested as an alternative to traditional centralized repositories [2]. However, critical issues such as data inte grity, access control, and content availability exist when using Peer-to-Peer Technologies [1].Osprey (http://osprey.ibiblio.org) addresses these problems by combining a flexible metadata management system with the BitTorrent Peer-to-Peer protocol. A Web database application provides searching and browsing of collection objects, and the Peer-to-Peer component lowers the bandwidth costs by employing distributed downloading. The Permaseed application supplies reliable, persistent Peer-to-Peer access to files in the digital repository.

  • omnivore integration of grid meta scheduling and peer to peer Technologies
    Cluster Computing and the Grid, 2008
    Co-Authors: Michael Heidt, Tim Dornemann, Kay Dornemann, Bernd Freisleben
    Abstract:

    Dedicated servers remain to be a common constituent of Grid job scheduling architectures, forcing site administrators to make compromises between administrative expenses and system reliability. Apart from requiring administrative attention, dedicated servers create single points of failure and should not be subjected to network churn. This paper presents the design and implementation of Omnivore, a fully decentralized job scheduling system, built on a Peer-to-Peer based meta-scheduler. Omnivore is able to cope both with node failures and network churn, eliminating the need for central administration and continuous resource availability. It is integrated into the Grid landscape (especially the Globus Toolkit 4) by means of the GridWay meta- scheduler to provide scalable distributed scheduling, replicated storage and system monitoring capabilities. Results obtained from an experimental evaluation of our implementation show that Omnivore is both scalable and resilient in the presence of node failures and network churn.
