Abstract: A domain description is received, by a processor, the domain description identifying a domain associated with a sensor input. The domain description is formatted according to a hierarchical naming structure. A training data set is selected from a plurality of training data sets based upon the received domain description and sensor input. A combination of a subset of classifiers for classifying the sensor input is selected from a set of classifiers based upon the selected training data set.

Abstract: In one embodiment, the invention is a method and apparatus for distributed policy evaluation. One embodiment of a method for evaluating a systems management policy, where the policy includes a condition and an action to be taken when the condition evaluates to TRUE, includes forwarding the policy, by a first autonomic manager, to a second autonomic manager and receiving at the first autonomic manager at least partial evaluation results for the condition from a third autonomic manager. The first autonomic manager, the second autonomic manager, and the third autonomic manager are arranged in a ring configuration such that the evaluating occurs in a cascading manner, and only the first autonomic manager has access to a policy storage from which the policy is retrieved.

Abstract: A logical expression of a policy is generated from another logical expression of a policy, for example, via a set of transformations, each of which comprises an input sub-expression and an output sub-expression. Any sub-expression of the input expression which matches an input sub-expression of a transformation rule is replaced with the output sub-expression of that transformation rule to form a sub-expression of the output expression.

Abstract: Embodiments of the present invention address deficiencies of the art in respect to e2e SLA support in a network of both manageable and unmanageable portions and provide a method, system and computer program product for e2e SLA compliance across both managed and unmanaged network segments. In one embodiment of the invention, a method for e2e SLA compliance across both managed and unmanaged network segments can be provided. The method can include identifying both a managed segment and an unmanaged segment of an e2e network for a communications path implicated by an SLA, determining an observed delay for the unmanaged segment of the e2e network, computing from a desired delay for the communications path and the observed delay a differential delay, and constraining the managed segment to meet the differential delay in order to assure meeting the desired delay for the communications path implicated by the SLA.

Abstract: A system and method for determining policy coverage and generating a suggested policy for gaps in the policy coverage includes determining policy coverage for one or more policies in a policy coverage space and determining regions uncovered by the policy coverage in the policy coverage space. Suggested policies are generated to cover the regions uncovered by the policy coverage. The policy coverage is supplemented with the suggested polices to complete coverage of a policy set.

Abstract: One embodiment of the present method and apparatus for improving data transfers in peer-to-peer networks includes receiving a search request message from a requesting node, where the search request message requests specific data. A responding node then sends a response message to the requesting node including a referral message comprising at least one referred node that is expected to have the requested data, based on knowledge of the referred node's previous incoming and outgoing data transfers. The responding node may also indicate that the responding node has the requested data. In addition to increasing the requesting node's view of the peer-to-peer network, this also enables the identification of nodes (e.g., referred nodes) with which the requesting node may wish to establish direct peer-to-peer connections, e.g., to build peer-to-peer communities of nodes having similar interests.

Abstract: Risks of change to a physical configuration are minimized. A request for a change to the physical system included in the physical configuration is detected, and all applications the physical systems that would be affected by the requested change are identified. All the applications and physical systems that would be affected by the requested change are replicated on a virtual system, including applications and the physical system to which the requested change is targeted and applications and physical systems that are dependent on the applications and the physical system to which the requested change is targeted. The requested change is applied to the virtual system. The virtual system is tested to determine whether the applied change produces desired results. If the applied change products the desired results, the requested change is applied to the physical system.
