摘要： Monitoring data communications performance over at least a portion of a network having a plurality of end-user terminals for accessing services over the network. In a training phase, parameter data indicative of data communications performance is retrieved from a set of terminals. In a modelling phase, Principal Component Analysis (PCA) is applied to the retrieved data to determine the principal component directions of variation. One or more models of data communications performance are then generated for that network portion in terms of one or more value ranges in a projection of the retrieved parameter data into a coordinate system defined by two or more of the determined principal components. In a monitoring phase. the same parameters are retrieved from a selected terminal served by the same network portion and projected into the coordinate system of the generated models to expose any significantly divergent behaviour, potentially indicative of a fault condition, which generates an alert.

摘要： A method and apparatus are provided for detecting a fault condition in a network. In a training phase, the method remotely retrieves selected parameters from a predetermined set of users network termination devices in order to generate one or more representative models of connectivity status using the retrieved parameters. Parameter retrieval takes place over substantially the same path through the network as used to supply services to a respective network termination device. In a monitoring phase, determining a measure of connectivity status for the set of users and comparing that with a corresponding model measure. Any significant variation from model measures may be indicative of a fault condition. The system may monitor service status in addition to connectivity. The invention may select representative subsets of user terminals to monitor in lieu of all terminals.

摘要： A method and apparatus are provided for detecting a fault condition in a network, making use of standard parameter data generated by a network termination device of a user of the network, the method comprising, in a training phase, the remote retrieval of selected parameters from a predetermined set of users' network termination devices in order to generate one or more representative models of expected operational status using the retrieved parameters and, in a monitoring phase, determining a measure of operational status for the set of users at some future time and comparing that with a corresponding expected model measure. Parameter retrieval takes place over substantially the same path through the network as used to supply services to a respective network termination device so that the models are generated in respect of communications over those elements of network infrastructure likely to affect operational status of the respective set of users in the event of a fault condition. Any significant variation from model measures may be indicative of a fault condition. Preferred measures of operational status include connectivity status and service status.

摘要： A method and apparatus are provided for monitoring data communications performance over at least a portion of a network having a plurality of network users each having, linked to the network, a network termination device for accessing services over the network. In a training phase, remote connections are established to the network termination device of each in a predetermined set of network users served by a predetermined portion of the network to retrieve parameter data generated by the device, the parameter data comprising values for a predetermined set of parameters indicative of data communications performance over that portion of the network. Principal component analysis is applied to the retrieved data to determine the principal component directions of variation. One or more models of data communications performance are then generated for that portion of the network in terms of one or more value ranges in a projection of the retrieved parameter data into a coordinate system defined by two or more of the determined principal components. In a monitoring phase,the same parameters are retrieved from a network termination device of a selected user served by the same portion of the network and projected into the coordinate system of the generated models to expose any significantly divergent behaviour, potentially indicative of a fault condition.
