摘要:
A method and system for managing a policy includes, in response to determining the presence of a conflict, determining a semantic equivalence between a component of a policy rule and at least one additional policy rule. The determining a semantic equivalence is performed by using a semantic reasoning algorithm that includes the steps of determining a first policy target of a first policy rule and a second policy target of a second policy rule, determining a meaning of the first policy target and a meaning of the second policy rule, assigning a confidence value based on the determined meaning of the first policy, assigning a confidence value based on the determined meaning of the second policy, performing a semantic comparison between the first policy target and the second policy target, and determining, based at least in part on the semantic comparison, the presence of a conflict between the first and second policy targets.

Determine (101) a particular task to be autonomously facilitated in cooperation with another entity that also has autonomous task facilitation capabilities and then identify (102) particular supportable task facilitation objects as correspond to the particular task to be facilitated. Then identify (103) particular supportable candidate capabilities as correspond to at least some of the particular supportable task facilitation objects followed by then determining (104), for at least some of the particular supportable candidate capabilities, a corresponding relative preference metric to provide a metricized preferences-and-cap abilities matrix as corresponds to the particular task and this particular apparatus. This metricized preferences-and-capabilities matrix can then be used (105) to negotiate a particular selection of capabilities to be employed in cooperation with the another entity when facilitating this particular task.

A method and system for evaluating performance of a policy rule (101) includes a memory (406) and processor (404) adapted for accessing at least one policy rule (101) having associated with it at least one policy event (102), at least one policy action (104), and at least one policy condition (103). Next, the policy rule (101) is associated with at least one policy evaluation event (105), at least one policy evaluation condition (106), and at least one policy evaluation action (107), wherein the policy evaluation event (105) is independent of the policy event (102) which triggers the policy rule (101). Performance of the policy rule (101) is then assessed by utilizing the policy evaluation condition (106) and the policy evaluation action (107).

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 system [100] is provided that includes a Model-Based Translation Layer [200] to accept an input event being formed in any of a pre-determined set of languages and protocols, and output an output message having a common language and protocol. The system [100] also includes a State Processing Layer [300] to (a) parse the output message to determine an event, an externally perceived state of the event, and an internally perceived state of the event; (b) determine a type of the event; (c) determine whether the externally perceived state of the event is substantially equivalent to the internally perceived state of the event; and (d) invoke policy control to lookup action functions to address the event in response to determining that a combination of the type of the event and the externally perceived state of the event is determined to be valid.
摘要:
The disparate data and commands from are received from a managed resource (102) and have potentially different semantics. The disparate data and commands are processed according to rules received from an autonomic manager (112) to produce a single normalized view of this information. The actual state of the managed resource is determined from the normalized view of disparate data. The actual state of the managed resource (102) is compared to a desired state of the managed resource (102). When a match does not exist between the actual state and the desired state, a configuration adjustment to the managed resource (102) and/or another resource is determined to allow the actual state to be the same as the desired state. Then, the configuration adjustment is applied to the managed resource (102). When a match exists between the actual state and the desired state, maintenance functions associated with the managed resource (102) are performed.

A system includes vendor specific converters [210, 215, 220, 225] to gather vendor-specific data from sensors [235, 240] and convert to normalized data. The vendor-specific data comprises at least a first input and a second input. The first input corresponds to a first language and the second input corresponds to a second language, where the first language is different from the second language. The vendor specific converters [210, 215, 220, 225] receive normalized commands and issue vendor-specific commands to a managed resource [165]. A converter module [230] receives the normalized data and converts to an output corresponding to a common language. The converter module [230] also receives and outputs normalized commands corresponding to the common language. Semantic processing logic [255] receives the normalized data and matches the normalized data against a predetermined set of knowledge bases and generates a new object to send to an autonomic manager [160].

A system includes object construction logic [700] and semantic augmentation logic [705]. The object construction logic receives events and data. It also identifies whether managed objects exist in a predefined set of at least one information model [205] and at least one ontology [240] corresponding to the events and data. The object construction logic [700] further deduces, based on the events and data, whether any previously unknown managed objects exist corresponding to the events and data. The semantic augmentation logic [705] augments at least one of the managed objects and the previously unknown managed objects with semantic information based on knowledge-based reasoning and state awareness, according to at least one installed policy to generate at least one new object and provide the at least one new object to an autonomic processing engine.
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.
