Relative autonomous accounting for peer-to-peer Grids: Research Articles
Concurrency and Computation: Practice & Experience(2007)
摘要
Here we present and evaluate relative accounting , an
autonomous accounting scheme that provides accurate results even
when the parties (consumer and provider) do not trust each other.
Relative accounting relies on the observed relative
performance amongst the parties. As such, the basic requirement
to use it is that resource consumers must also be resource
providers. Relative accounting is totally autonomous in the sense
that it uses only local information, i.e. there is no exchange of
information between the parties. This allows for the deployment of
the autonomous accounting without requiring any sort of
identification infrastructure, such as certificate authorities. Not
requiring trust or sophisticated infrastructure makes relative
accounting a perfect fit for peer-to-peer Grids, which aim to scale
much further than traditional Grids by allowing free unidentified
entry into the Grid. Our results show that relative accounting
performs very close to a perfect accounting, whose implementation
is infeasible in most systems, including those we target. Relative
accounting was developed to work with OurGrid, a peer-to-peer Grid
in production since December 2004, but it can also be used in other
peer-to-peer Grids. Copyright © 2006 John Wiley & Sons,
