摘要:
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.
摘要:
A system, method, and information processing system manage a network. At least one contract including one or more components is received at a network that uses a component based architecture. A first operation (422) in the set of operations associated with the contract (114) is mapped to a policy rule event (424) associated with at least one policy rule (116). A second operation (426) in the set of operations associated with the contract (114) is mapped to at least one policy rule condition (428) associated with the policy rule (116). A third operation (430) in the set of operations associated with the contract (116) is mapped to a policy rule action (432) associated with the policy rule (116). A fourth operation (440) in the set of operations associated with the contract (116) is mapped to a policy rule condition (442) associated with the other policy rule (420).
摘要:
A method, information processing system, and system manage network entities. At least a portion of at least one information model (120) for a first managed entity (104) and at least a second managed entity (106) is accessed. The portion of the at least one information model (120) includes a set of capabilities (542) associated with the first managed entity (104) and second managed entity (106), respectively. A first set of capabilities (708) supported by the first managed entity (104) and a second set of capabilities (710) supported by the second managed entity (106) are identified based on the portion of the at least one information model (120). A set of common capabilities (712) from the first set of capabilities (708) and the second set of capabilities (710) that is supported by both of the first managed entity (104) and the second managed entity (106) is determined.

摘要:
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.
摘要:
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.
摘要:
A method and a device for managing state changes (Init, Run, Suspend, Resume, End) of a managed entity (302) includes a memory (906) and a processor (904) adapted to represent each state change of a managed entity (302) as a separate node (1-5) in a graph (300), represent a state transition as an edge (Eij) 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 (Eij) 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 (Eij), the first and second nodes representing an initial and a final state change of the managed entity (302).
摘要:
A method and information processing system manage policy elements in an information processing system. At least one policy element (110) from a plurality of policy elements stored in at least one policy repository (108) is retrieved. The plurality of policy elements includes at least one of a plurality of reusable policy rules (110), a plurality of reusable policy rule components (118, 120, 122), a plurality of reusable policy rule templates, and a plurality of and policy rule component templates. A new reusable policy element is created from at least one of the policy element (110) that has been retrieved and a default policy element. The new reusable policy element is stored in the at least one policy repository (108). A reusable policy element is queried using metadata (224) associated with the reusable policy element.
摘要:
A method for modifying policy elements is disclosed. At least one reusable policy element (110) is retrieved from at least one repository (108). The reusable policy element (110) includes at least one of a reusable policy rule (110), a reusable policy rule component (118, 120, 122), a reusable policy rule template, and a reusable policy rule component templates. The reusable policy element (110) is modified by one of editing the reusable policy element (110), and deleting the reusable policy element (110).
