Filed:

Apr 27, 2007

Appl. No.:

11/741141

Inventors:

Gregory W. Cox - Schaumburg IL, US
David L. Raymer - Watauga TX, US
John C. Strassner - North Barrington IL, US

International Classification:

G06F 21/00

US Classification:

726 1, 726 13

Abstract:

A method and computer program product for detecting a policy conflict in a managed system includes examining a plurality of policy rules for overlapping policy targets, in response to finding no overlapping policy targets, reporting that the policy rules do not conflict, and in response to finding overlapping policy targets, examining the plurality of policy rules for at least two rules having a same condition and a same event, and, in response to not finding at least two rules having a same condition and a same event, reporting that the policy rules do not conflict.

Inventors:

John C. Strassner - North Barrington IL, US
David L. Raymer - Watauga TX, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G05B 17/00

US Classification:

700 29

Abstract:

A method and a device for managing state changes (Init, Run, Suspend, Resume, End) of a managed entity () includes a memory () and a processor () adapted to represent each state change of a managed entity () as a separate node (-) in a graph (), represent a state transition as an edge (E) connecting a first node with a first state value to a second node with a second state value, and determine a cost (C) of each edge (E) that is part of a set of edges (E) that form at least two paths connecting the first node and the second by applying at least one policy (P) to each edge (E), the first and second nodes representing an initial and a final state change of the managed entity ().

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G06F 17/20
G06F 7/60

US Classification:

704 1, 703 2, 704 4

Abstract:

A method and system for managing a policy includes a memory adapted to store at least one policy, residing at a first abstraction level, where each policy includes a plurality of language elements in a first vocabulary set and a processor communicatively coupled to the memory and adapted to perform semantic resolution using a set of ontologies by mapping at least one of the language elements in the first vocabulary set to at least one of a plurality of language elements in a second vocabulary set, the second vocabulary set having at least one of a different grammar and a different vocabulary from the first vocabulary set create a second policy, in response to the semantic resolution.

Appl. No.:

Inventors:

John C. Strassner - North Barrington IL, US

Assignee:

International Classification:

G06F 9/46

US Classification:

718100

Abstract:

A method and system are disclosed for changing the structure of one or more policies and/or the order of application of one or more policies to resolve conflicts among a set of policies using graph-theoretic techniques. Policies are used to govern the states of managed entities (e.g., resources and services). The set of states of the set of managed entities are represented as nodes of a graph. The output of the set of applicable policies governing all or part of the nodes is then used to control the transition between some or all nodes in the graph.
