摘要： A control device of the present invention is for calculating allocation information regarding the allocation of wireless resources of a plurality of base stations to a plurality of user devices. The control device includes: information managing means for storing request data amounts of the user devices; calculating means for calculating an estimated waiting time for each of the user devices by dividing the request data amount by an available bandwidth, and, using the maximum transmission power of the base stations as a constraint, calculating the allocation information regarding the allocation of the wireless resources of the base stations to the user devices so as to minimize the estimated waiting time of the user device having the highest estimated waiting time; and outputting means for outputting the allocation information that was calculated by the calculating means.

摘要： Techniques for extracting a set of highly correlated logs without user's prior knowledge of generation rules of logs generated by a machine. A log analysis apparatus includes: a template storage unit configured to store templates for log messages; a template determination unit configured to determine templates corresponding to log messages provided from a to-be-monitored host from the stored templates; an event candidate extraction unit configured to detect templates determined for log messages provided from the same host from the determined templates and extract a sequence of the detected templates as an event candidate; and an event extraction unit configured to extract a sequence of frequently occurring templates as an event from the extracted event candidate.
