摘要： A device may receive a first portion of network traffic associated with a flow. The device may perform a first upper layer inspection of the first portion of network traffic associated with the flow. The device may identify a set of parameters of the flow based on performing the first upper layer inspection of the first portion of network traffic associated with the flow. The device may determine, based on the set of parameters, a sampling rate at which to perform a second upper layer inspection of a second portion of network traffic associated with the flow. The device may instruct a lower layer to use the sampling rate to provide the second portion of network traffic associated with the flow for the second upper layer inspection. The device may perform the second upper layer inspection of the second portion of network traffic associated with the flow based on receiving the second portion of network traffic associated with the flow from the lower layer. The device may perform an action with regard to the flow based on a result of performing the second upper layer inspection.

摘要： Creation of new edges in a network may be used as an indication of a potential attack on the network. Historical data of a frequency with which nodes in a network create and receive new edges may be analyzed. Baseline models of behavior among the edges in the network may be established based on the analysis of the historical data. A new edge that deviates from a respective baseline model by more than a predetermined threshold during a time window may be detected. The new edge may be flagged as potentially anomalous when the deviation from the respective baseline model is detected. Probabilities for both new and existing edges may be obtained for all edges in a path or other subgraph. The probabilities may then be combined to obtain a score for the path or other subgraph. A threshold may be obtained by calculating an empirical distribution of the scores under historical conditions.

摘要： A system, apparatus, computer-readable medium, and computer-implemented method are provided for detecting anomalous behavior in a network. Historical parameters of the network are determined in order to determine normal activity levels. A plurality of paths in the network are enumerated as part of a graph representing the network, where each computing system in the network may be a node in the graph and the sequence of connections between two computing systems may be a directed edge in the graph. A statistical model is applied to the plurality of paths in the graph on a sliding window basis to detect anomalous behavior. Data collected by a Unified Host Collection Agent (“UHCA”) may also be used to detect anomalous behavior.

摘要： A communication system configured to enhance communication spectral efficiency while maintaining an acceptable level of system robustness. Various combinations of modulation, code rate, and antenna usage scheme, are combined to create a hierarchy of modulation and communication schemes (MCS), such that each higher MCS level represents an enhanced degree of spectral efficiency, traded off for a lowered degree of system robustness. Included also are embodiments of methods testing the quality of data transmission and reception at difference MCS levels, and then raising or lowering MCS levels in order to enhance communication spectral efficiency while not falling below the minimally acceptable level of system robustness.

摘要： A smoothed transport block size is forecasted by predicting future value information based on historical time series data obtained at an e-Node B. The historical time series data includes historical transport block size information and historical modulation and coding scheme information. A mapping function is used to correlate the future value information with historical transport block size information. Once the mapping function is determined, the mapping function forecasts the average transport block sizes by inputting the future value information into the mapping function. The smoothed transport block sizes and the future value information is then transmitted to an application server and/or an application client at a user equipment to control an operation of an application.

摘要： A method and a network node (110, 111) for determining first channel state information in an upcoming time slot for use by a first radio network node (111) when determining a set of radio transmission parameters for a transmission between the first radio network node (111) and a second radio network node (121) are provided. The network node (110, 111) receives (201) second channel state information for said upcoming time slot. Furthermore, the network node (110, 111) determines (207) third channel state information for said upcoming time slot. The second and third channel state information are at least partly non-overlapping with each other. Next, the network node (110, 111) determines (208) the first channel state information, for said upcoming time slot, based on the second channel state information and the third channel state information.

摘要： Correction data units for data packets of a data stream are generated. A correction data unit is based on a set of the data packets of the stream. The stream is transmitted over a lossy communication channel. A performance measure to be optimized is selected, which relates to the recovery of lost data packets of the stream. A coding requirement is determined. For the generation of the correction data units, it is determined, within the constraints of the coding requirement and based on previously generated correction data units, which of the data packets in the stream to include in the set on which the generation of the correction data unit is to be based to thereby optimize the selected performance measure. A generated correction data unit is generated based on a respective set of the data packets of the stream. The generated correction data units are included in the stream.
