Abstract:
As Grids enlarge their boundaries and users, some of their
functions should be decentralized to avoid bottlenecks and
guarantee scalability. A way to provide Grid scalability is to
adopt Peer-to-Peer (P2P) models to implement non
hierarchical decentralized Grid services and systems. A core Grid
functionality that can be effectively redesigned using the P2P
approach is resource discovery. This paper proposes a P2P
resource discovery architecture aiming to manage various Grid
resources and complex queries. Its goal is two-fold: to address
discovery of multiple resources, and to support discovery of
dynamic resources and arbitrary queries in Grids. The architecture
includes a scalable technique for locating dynamic resources in
large-scale Grids. Simulation results are provided to demonstrate
the efficiency of the proposed technique.
