In the method, characteristic information of a first application is selected. Bit lines of a position designated by a mask included in the characteristic information are examined from packets transferred via the packet flow. A ratio of the number of examination results of coincidence to the number of all input packets is calculated. When the ratio exceeds a first threshold included in the characteristic information, it is determined that the packet flow belongs to the first application. | 2013-07-04 |
20130170378 | METHOD AND A SYSTEM FOR LOCALIZATION IN INDUSTRIAL WIRELESS SENSOR NETWORK - A method and system are disclosed for localization in an industrial wireless sensor network by identifying a sensor node of a field device for localization, and determining the location information of the sensor node associated with the field device. The determined location information is stored in the field device, in one or more modules of the wireless network management component, and/or an operator portal. Operation can be indicated upon the joining of the field device into the network or during the commissioning of the industrial wireless sensor. | 2013-07-04 |
20130170379 | Detection of Encrypted Packet Streams Using Feedback Probing - Methods, systems, and devices are disclosed for detecting encrypted Internet Protocol packet streams. A probe stream having a known observable parameter is generated. The observable parameter exhibits a known characteristic of a known type of data encrypted within a stream of packets. The probe stream is communicated to a network element via a communications network. When the probe stream is received by the network element, the network element can compare the known observable parameter to an actual value. Any difference between the known observable parameter and the actual value can be used to correct for network-induced variation and other effects, thus ensuring accurate detection and identification of data types within encrypted streams of packets. | 2013-07-04 |
20130170380 | ADAPTING A COMMUNICATION NETWORK TO VARYING CONDITIONS - Systems and methods are disclosed for adapting a communication system to varying conditions. Using some form of discovery protocol, the communication standards supported by at least two communicants are determined. Each communicant may then periodically monitor the quality of the channel established by the communication standard and dynamically select a set of one or more communication standards to use for communicating. Further, when communicants share common non-standard parameterized implementations of communication standards, changes to the protocols which the communication standards comprise can be used to add options for a more dynamic response to changing conditions than is possible when adhering only to an established communication standard. | 2013-07-04 |
20130170381 | BAND CONTROL SYSTEM FOR A DIGITAL SUBSCRIBER NETWORK AND BAND CONTROL METHOD THEREFOR - A band control system of the present invention is applicable to a digital subscriber line network in which a first apparatus and a second apparatus situated at a subscriber station and a center, respectively, are interconnected by a metallic cable for interchanging at least a digital data signal with each other. The band control system includes a commanding device included in one of the first and said second apparatuses for monitoring the receipt of ATM (Asynchronous Transfer Mode) cells from the other apparatus and sending, based on the result of monitoring, a band variation command to the other apparatus to thereby cause it to vary a band by using a frequency band not used for signal transfer. A band varying device is included in the other apparatus for receiving the band variation command and varying the band in accordance with the command. | 2013-07-04 |
