Beyond Music Sharing: An Evaluation of Peer-to-Peer Data Dissemination Techniques in Large Scientific Collaborations

摘要

The avalanche of data from scientific instruments and the ensuing interest from geo_graphically distributed users to analyze and inter_pret it accentuates the need for efficient data dissemination. A suitable data distribution scheme will find the delicate balance between conflict_ing requirements of minimizing transfer times, minimizing the impact on the network, and uni_formly distributing load among participants. We identify several data distribution techniques, some successfully employed by today's peer-to-peer net_works: staging, data partitioning, orthogonal band_width exploitation, and combinations of the above.
