4. GGF - © 2003 www.sandial.com 4 Background Policy-based management provides an abstraction that enables the definition of system behaviors that are independent of Grid implementations. Working groups in the IETF, IRTF, and DMTF have defined a policy framework and information model, and the DMTF continues to extend the information model to higher-level abstractions, that manage the business objectives via service-level agreements and service-level objectives, in addition to, the information model for the management of the underlying resources. In Grid environments, policy-based management may be used to provide scalable, implementation-independent configuration for a range of infrastructure resources, as well as the many other grid functions that perform resource allocation or user experience management.

GGF - © 2003 www.sandial.com 6 Charter Redefine as RG (?) – scope (use cases and then requirements) Policy Definition - The Grid Policy Architecture Working Group will acquire the requirements and develop the architecture for interoperable policy based management, and for how the policies are described, evaluated, stored, managed, distributed, and enforced (maybe too broad). Since policies may also be associated with instrumentation to provide feedback into evaluating the effectiveness of the policies, the requirements and architecture should also provide a framework for associating the appropriate metrics and instrumentation with the policies. This group will not define what the policies, metrics and instrumentation will be, but will interface with other Working Groups such as those in the GGF Scheduling and Resource Management Area and the GGF Security Area whose charter it is to define the specifics.

7. GGF - © 2003 www.sandial.com 7 Revised Charter Redefine as RG (?) – scope (use cases and then requirements) Policy Definition - The Grid Policy Architecture Working Group will acquire the requirements for interoperable policy based management. This would be done for OGSA compliant and non-OGSA compliant grids. The goal is to define use cases, requirements, and span Working Groups to work on an architecture for describing, evaluating, storing, managing, distributing, and enforcing policy across grid instantiations. Since policies may also be associated with instrumentation to provide feedback into evaluating the effectiveness of the policies, the requirements and architecture should also provide a framework for associating the appropriate metrics and instrumentation with the policies. This group will not define what the policies, metrics and instrumentation will be, but will interface with other Working Groups such as those in the GGF Scheduling and Resource Management Area and the GGF Security Area whose charter it is to define the specifics. The Policy Research Group (Policy-RG) will look at and evaluate Policy Models that have been put forth by other Standards Bodies (such as DMTF, IETF, SNIA, etc …) for applicability.
