Abstract
In a multi-organization environment like the GRID, each institute
might want to apply some boundaries on how its resources are being
utilized by other institutes. A disagreement between the multi-Virtual
Organizations (VOs) might happen in the security aspect for the
policy framework. Mobile Grid Services has given the ability to move
jobs, data and application software from nodes to nodes during jobs’
execution in the grid environment. It has also solved some of the
lack in finding suitable resources for the jobs. To facilitate the ability
to support mobile resource sharing between multiple heterogeneous
VOs, an authorization policy management framework is needed
to support authorization for heterogeneous authorization systems.
Traditional authorization policy management frameworks act well in
authorization policy for a single VO where the contributing hosts grant
the permission to follow a global authorization system. However most
of policy management tools do not provide a clear support for sharing
mobile resources between multiple heterogeneous VOs. To solve this
problem, we present a dynamic and heterogeneous policy management
framework that can give a clear policy definition about the ability to
move jobs, data and application software from nodes to nodes during
jobs’ execution in the grid environment. We introduce an architecture
for policy based resource management in the case of mobile sharing,
and a scenario that explain the advantages of mobility mechanism and
the role of policy in the grid systems. To check the performance of this
architecture, a set of experiments had conducted. The results, analysis
and the overheads estimation are presented in this journal.
