Abstract: According to the teachings herein, provisioning operations carried out via electronic processing in a communication network (60) benefit from the use of reordered workflows (20) having task orderings that are at least partly optimized with respect to task failure probabilities and/or resource-blocking penalties. The reordered workflows (20) are obtained by optimizing predefined provisioning workflows (10). Each predefined workflow (10) comprises two or more tasks (12) ordered along one or more task execution paths (14) in a task tree (16), according to a default task ordering that reflects any required inter-task dependencies but, in general, does not reflect any optimization in terms of failure penalties, resource blocking, etc. Among the several advantages provided by the teachings herein, carrying out provisioning operations in accordance with reordered workflows (20) wastes fewer compute cycles and reduces the needless blocking of network resources in the event of provisioning task failures.

Abstract: Guest memory data structures are read by one or more read operations which are set up to handle page faults and general protection faults generated during the read in various ways. If such a fault occurs while performing the one or more read operations, the fault is handled and the one or more read operation is terminated. The fault is handled by either dropping the fault and reporting an error instead of the fault, by dropping the fault and invoking an error handler that is set up prior to performing the read operations, or by forwarding the fault to a fault handler that is setup prior to performing the read operations. If no fault occurs, the read operations complete successfully. Thus, under normal circumstances, no fault is incurred in a read operation on guest memory data structures.

Abstract: The flow of events though an event-analysis system is controlled by a number of event throttles which filter events, prioritize events and control the rate at which events are provided to event-processing components of the event-analysis system. Incoming events to the event-analysis system are associated with a profile, and a metrics engine generates metrics based on the incoming events for each profile. The flow of events to the metrics engine is controlled on a per profile basis, so that excessive generation of new metrics and new profiles is limited. If the system from which the events originate is compromised, metrics associated with compromised profiles may be frozen to avoid corrupting existing metrics. Processing of events and anomalies by analysis engines within the event-analysis system may be delayed to allow the accumulation of metrics necessary for accurate analysis.
