Abstract

We merge concepts from P2P into Data Grid and present a web-based Data Grid, called GridFS, for the distributed sharing of educational resources. GridFS extends Data Grid by making replicas writable in practice. We propose a push-version-number consistency (PVNC) model and a writer/reader protocol to implement it. PVNC eliminates nearly all read latency and lessens the network utilization. We believe GridFS and PVNC would benefit hierarchical web cache systems and digital libraries.
