METHOD OF NETWORK NODE PERFORMANCE RANKING

摘要

The invention relates to a method of determining maintenance priority for different portions of a CATV network. By calculating a health score for each node of the network based on a plurality of measurements performed downstream from the nodes, the nodes and the downstream segments of the network may be ranked according to their health score values, and the maintenance of the network segments may be prioritized based on the health ranking of the corresponding nodes. The health score for a node may be computed based on a plurality of tilt- and modulation-normalized frequency scans of the network signal.

1. A method for evaluating a node performance in a network, the method comprising:
a) measuring a network signal provided by the node and collecting spectral scan data therefore; b) computing a set of signal health indicators from the collected spectral scan data; c) comparing each signal health indicator to one or more predetermined threshold values; and, d) computing a test score based on the set of signal health indicators for the node to evaluate the node performance at the time of the measurement.
