An Incremental Policy Deployment Model Based on Domain

Policy based management is an effective approach to manage distributed system and large scale system. With the basic concepts of policy, domain and policy target introduced, a general policy deployment model is purposed which based on domain layer architecture. It assumes that policies are stored in the most close domain to target, and the whole system changes according to the increment arithmetic. The general model is independent of the underlying concrete policy enforcement mechanisms and can be employed in mixed policy environments.
