ABSTRACT
Shared dataspaces à la Linda, and the underlying data-driven coordination model, have been successfully exploited in the development of a huge variety of applications, going from parallel computing to web-based collaborative work. In this paper we consider a novel class of applications, namely those developed for peer-to-peer networks à la Gnutella or FreeNet. We discuss the problems which arise when trying to exploit the original Linda coordination model in this new scenario. In order to address these problems, we introduce PeerSpaces, a new coordination model particularly suited for the realm of peer-to-peer network applications, and we present a prototypical implementation of this coordination model based on the JXTA peer-to-peer technology.

On the implementation of robust distributed peerspaces
PDT '11: Proceedings of the Workshop on Posters and Demos TrackWith respect to temporal and spatial coupling properties, coordination models based on the persistent tuple spaces can be easily integrated with peer-to-peer infrastructure for scalability and robustness. With a system that forms a persistent shared ...
An Efficient Hybrid Peer-to-Peer System for Distributed Data Sharing
Peer-to-peer overlay networks are widely used in distributed systems. Based on whether a regular topology is maintained among peers, peer-to-peer networks can be divided into two categories: structured peer-to-peer networks in which peers are connected ...
