Abstract:
1. A computer-implemented method, comprising: for each of a plurality of communications channels arranged to convey data in a network, using one or more processors configured and arranged for: accessing channel data that specifies at least one channel characteristic for the communications channel; normalizing the channel data based on reference channel data; generating status scores based on the normalized channel data, the status scores being a vector of values representing the status of the communications channel; normalizing the status scores for each communications channel that is in a valid operating state; adjusting the status scores based on variations of the channel data; and determining whether a network status has changed based on status score variations at least in part including identifying reference status scores for the channel, the reference status scores corresponding to a network event, and including determining that the network status has changed when the status score variations are indicative of the network event based on the reference status scores; and generating status data based on the determination; accessing status scores generated for channel data representing a channel status during a previous network event; indexing the status scores as reference status scores for the network event; accessing data that identifies relationships between the reference status scores and the network event; and determining a network status based on the status score variations and the reference status scores according to the data identifying relationships between the reference status scores and the network event.
