Abstract: A method of controlling a home appliance connected to the Internet via a gateway and an appliance control server of an appliance control cloud. The appliance executes control commands for operating the appliance received from the Internet via the gateway only if the commands are received from the appliance control cloud. A control command supply server of a control command supply cloud is connected to the home appliance control cloud via the Internet, and has at least one repository storing control instruction sets to operate the appliance. The method includes authenticating a request for remote control of the appliance received from the control command supply server via the Internet, and, responsive to positive authentication, forwarding control commands from the control command supply server to the appliance. The control commands are part of a set of instructions from the repository selected based on input received by a user terminal device.

Abstract: Data information, represented by electric or wave signals, or data information within the artificial or natural databases and storage media, such as for example DNA, encoded as a sequence of symbols, is, for the purpose of its concealing and simultaneously preserving its select local data information segments, partitioned within a physical medium, such as especially computer hardware, physical communication channel, physical storage medium or biological material, into short overlapping data segments. The studied local data information segments are contained within the short segments in their entirety. These partitioned short segments constitute the first group and to at least one short segment of the first group, data, encoded as selected symbols, are pre-pended or appended, to the symbols of the short segments of the first group. The resulting mixture of segments is interconnected into a sequence of data. The entire process may be repeated multiple times.

Abstract: A method, computer program product, apparatus, and system that detects a substring in an input data string by producing a fingerprint of a portion of the data string and comparing the fingerprint of the portion of the data string to at least one predefined fingerprint. The predefined fingerprint may be a fingerprint of a portion of a predefined pattern of interest. If the fingerprints match, further pattern recognition processing may be performed on the input string.

Abstract: Methods and apparatus are provided for controlling flow rates of a plurality of data packet flows into a queue 4 corresponding to a resource 3 of a network device 1. The flows comprise a set 7 of non-responsive flows, and a set 8 of other flows which may comprise responsive flows and/or flows whose responsiveness is unknown. The flow rates are managed in accordance with a queue management scheme such that adjustments are made to each flow rate in dependence on excess bandwidth in the resource, the amounts of the adjustments being dependent on one or more adjustment parameters for each flow. An error signal is generated based on the deviation from a desired allocation ratio of the ratio of the total flow rates into the queue 4 for the sets of flows 7, 8. At least one adjustment parameter for at least one flow is then varied in dependence on the error signal in such a manner as to reduce the aforementioned deviation.

Abstract: Load balancing apparatus for a data communications network comprises hash logic for computing a hash function on incoming data packets. A threshold detector is connected to the hash logic for triggering, in response to utilization of the downstream objects exceeding a predefined threshold, redefinition in the hash logic of parameters of the hash function from a first set of parameters to a second set of parameters for redistributing the data packets amongst the downstream objects.

Abstract: The present invention provides an improved method and a system for processing data packets in a router. The router includes a plurality of input/output ports and more than one packet processing units. The packet processing units derive from a piece of information associated to each data packet one output port to forward the data packet to. In response to a data packet arriving at one input port one packet processing unit is determined. The determined packet processing unit is then requested to derive a respective output port. The output port is derived from a piece of information within the packet. An identification identifying the respective output port is in the following returned to the requesting unit. Finally, the data packet is forwarded to the identified output port. The method and system according to the present invention optimize advantageously resource utilization that leads to higher packet processing speed and helps to lower the costs and power requirements.
