Communication technologies are evolving along with Grid Computing. The trend of Open Grid Services Architecture (OGSA) is that "everything" is represented as a service, which will be provided to users without any kind of distinctions related to network technology, operative platform, administrative domain, etc. As a result of this trend, there has been a significant management requirement increase in order to cope with the yet elusive rapid and autonomous service creation, deployment, activation and management. This paper describes a proposal to cope with the above mentioned management requirements. Our policy-based management approach enables the establishment, configuration and administration of services on a Grid network that uses the Globus Architecture for Reservation and Allocation (GARA) as an interface for reservation and provisioning of grid resources.
