Abstract: A system, computer program and method for transmitting requested data from a data source in response to data transmission requests from at least one electronic device according to differential rates of throughput. Data transmission requests are classified into one of a plurality of throughput classes, with each throughput class having an assigned rate of throughput. A proportion of data transmission requests to be processed from each throughput class is selected such that each data transmission request has a rate of throughput approximating the assigned rate of throughput of its class. The requested data is then sent from the data source to the electronic device.

Abstract: For port scanning an authentication bit sequence is created as an output of an authentication transformation, the authentication transformation having as input at least a given destination address and a given secret key. The authentication bit sequence is embedded in at least one authentication port scan event packet comprising the given destination address. At least one authentication port scan event packet is broadcast. Then, further port scan event packets are broadcast with given port identifiers and the given destination address. For port scanning detection, a received authentication bit sequence is derived from a least one authentication port scan event packet with identical source and destination addresses. Further port scan event packets are accepted with given port identifiers and the given destination address if authentication is given.

Abstract: A medical guide service for a doctor, a patient, a general user, and a medical institution. The medical guide system may include a unit that creates medical record data and a unit that extracts the medical record data for each patient. The unit that extracts the medical record data uses examination data before a predetermined dividing point in a chronological order as before-dividing-point data and treatment data after the predetermined dividing point in the chronological order as after-dividing-point data. A unit extracts a treatment pattern from the after-dividing-point data. Another unit derives a rule that associates the examination results with the treatment pattern from the treatment pattern and the before-dividing-point data.

Abstract: A method and apparatus are provided for detecting peer-to-peer communication on a data communication network, between an internal client machine within an internal address space and an external client machine. The method includes routing all messages addressed to internal client machines to an analysis device. The analysis device identifies messages pertaining to peer-to-peer communication and identifies the internal client machine to which the messages of a specified nature were addressed. The analysis device terminates the connection with the external client machine if the establishing of the peer-to-peer communication is in violation of a pre-determined internal network rule.

Each switching element is adjustable from a low resistance state to a high resistance state by a control signal. The inductor outputs current to a circuit load. The circuit may be operated in a first mode such that the output is adjustable between the supply voltage and half the supply voltage. Alternatively, in a second mode of operation, the output is adjustable from half the supply voltage to a ground voltage.

Abstract: A plurality of landmarks selected from a source weighed graph on which a path search is performed; and the shortest path lengths between landmarks, and the shortest path lengths from vertices to landmarks adjacent to the respective vertices are calculated, and are stored in a memory device so as to be later referable. Routines for calculating upper and lower limits of the shortest path length corresponding to two vertices v and w are prepared by using expressions derived from quadrangle inequalities formed of the two vertices v and w as well as two landmarks adjacent to the respective vertices v and w. In response to a call from an A* search program, these routines return the upper limit or the lower limit of the shortest path length corresponding to v and w by referring to the shortest path lengths between landmarks, and the shortest path lengths from vertices to landmarks adjacent to the respective vertices, which have been previously stored in the memory device.

Abstract: A method, system and computer program product for facilitating network data packet management. In one embodiment, a controller is configured to receive data packets. Incoming data packets are stored in DMA mapped packet buffers. A time stamp is associated with the packet buffers. When the associated time stamp exceeds a defined threshold, the controller is configured to copy the packet buffers stored in DMA memory to non-DMA memory. Once copied, the DMA memory previously used to store the packet buffers is available to receive new data packets. The controller is configured to continue copying aged packet buffers to non-DMA memory until an unallocated amount DMA memory is reached.

Abstract: Software license management systems are provided in which a license to use a software product is represented by a data token. The systems have a software controller for controlling use of the software product at a user device, and a license management server for communicating with the software controller via a data communications network. The software controller allows use of the software product at the user device substantially only during a use period associated with a current data token supplied to the software controller by the license management server. An exchange token can be supplied to another, similar software controller when necessary to transfer the license, e.g. in the event of a breakdown. The software controller is adapted to supply either the current data token, or the exchange token, to the license management server to be exchanged for a new data token.

The system may also include a buffer to receive the processed at least two data packets from the error control decoder. The error control decoder may apply a logic OR operation to the uncorrectable error signal related to the processing of the at least two data packets to produce a global uncorrectable error signal.

Abstract: A system to improve memory reliability in computer systems that may include memory chips, and may rely on a error control encoder to send codeword symbols for storage in each of the memory chips. At least two symbols from a codeword are assigned to each memory chip and therefore failure of any of the memory chips could affect two symbols or more. The system may also include a table to record failures and partial failures of the codeword symbols for each of the memory chips so the error control encoder can correct subsequent partial failures based upon the previous partial failures. The error control coder is capable of correcting and/or detecting more errors if only a fraction of a chip is noted in the table as having a failure as opposed to a full chip noted as having a failure.
