摘要： A method of managing a telecommunications network, the telecommunications network having a first user and a second user, the method comprising the step of: ascertaining a competitive characteristic associated with the first user and a competitive characteristic associated with the second user; comparing the ascertained competitive characteristics; identifying whether there is a disparity between the competitive characteristics that exceeds a threshold, thereby to identify a competitive advantage associated with the first or second user; and if it is identified that the disparity exceeds the threshold, adapting a network configuration of a network connection associated with the first user so as to offset the competitive advantage associated with the first or second user.

摘要： This disclosure provides a method of controlling an electromagnetic field detector by causing a first phase shift to be applied to a second probe signal path so as to cause a variation in a change in intensity of combined first and second paths of a probe signal; obtaining data indicating a second phase shift to be applied to the second probe signal path so as to increase the change in intensity of the combined first and second paths of the probe signal, wherein the second phase shift is determinable from a variation in the change in intensity of the combined first and second paths of the probe signal caused by the first phase shift; and causing the second phase shift to be applied to the second probe signal path.

摘要： A computer-implemented method of training a network anomaly detection system is disclosed. The method involves generating synthetic benign network data and synthetic anomalous network data and combining the synthetic benign network data and synthetic anomalous network data to generate combined synthetic network data having a predetermined density of anomalous network data. The combined synthetic network data is provided to a trained anomaly detection model, and an accuracy score is determined that is representative of how accurately the trained anomaly detection model recognizes anomalous activity in the combined synthetic network data. If the accuracy score is less than a threshold value, the anomaly detection model is trained with additional network data and a new accuracy score is determined. Otherwise, the predetermined density of anomalous network data is reduced and a new accuracy score is determined until a predetermined stopping criterion is met.

摘要： A computer-implemented method of operating a software-defined network, the method comprising: obtaining specifications of a plurality of data plane elements which together form a path through a data plane suitable for carrying traffic associated with a category of applications and/or services; determining, based on the specifications, which one or more of a plurality of security profiles the path is capable of complying with; selecting one of the one or more security profiles to be an initial security profile; routing traffic associated with the category of applications and/or services via the path in compliance with the initial security profile; subsequently obtaining an alert that network performance conditions have worsened; and responsive thereto: selecting a different one of the plurality of security profiles, that is less resource-intensive than the initial security profile, to be a replacement security profile; and routing traffic associated with the category of applications and/or services in compliance with the replacement security profile.

摘要： Malware Protection A computer implemented method, computer system and computer program are provided for protecting against malware. The method trains a classifier to classify a domain name as being either legitimate or illegitimate, wherein a classification of illegitimate indicates that the domain name was generated by a Domain Generation Algorithm used to generate domain names for malware. The method retrains the classifier using an active learning technique by: using the classifier to determine a respective classification of each domain name in a set of domain names; performing a respective domain name system. DNS, query for each domain name in the set; labelling one or more domain names in the set based on the classification of those domain names and the outcome of the respective DNS queries for those domain names; and using training data comprising the labelled one or more domain names to retrain the classifier. The method uses the classifier to classify a domain name that is the subject of a DNS query from a computer system in a network. The method takes one or more predetermined actions for mitigating or preventing the activity of the malware in response to the domain name being classified as illegitimate.

摘要： The invention provides a method of media content delivery, where the time taken to deliver each chunk of content is measured, from which the stability or consistency of delivery times are calculated. The amount of data buffered at the user's device awaiting decoding and play-back can then be adjusted (such as by playing out the content slower or quicker), in order to achieve a good compromise between continuous play-out and low end-to-end delay, taking into consideration the current network characteristics.

摘要： A computer implemented method of access control for a user device having at least one component for determining behaviors of the user. The method including accessing a first machine learning classifier trained based on at least one prior behavior of the user using the device, the classifier classifying user behavior as compliant or non-compliant. The method further including, in response to a determination that a subsequent behavior is classified as non-compliant, accessing a second machine learning classifier trained based on at least one prior behavior of the user using the device where the prior behavior is classified as non-compliant by the first classifier. The method further including, in response to a determination that the subsequent behavior is classified as non-compliant by the second classifier, requesting a credential-based authentication of the user and constructively training one of the machine learning classifiers based on the credential-based authentication result.
