Abstract

Method and Apparatus for Network Problem Segment Isolation. The present invention provides a method for characterizing network segment quality for a segment transmitting messages from a first endpoint to a second endpoint on a network. The method includes the step of receiving messages transmitted between the first and second endpoints. The messages include a first set of quality metrics for message transmission from the first to second endpoint for both the first and second segments and a second set of quality metrics for message transmission from the first endpoint to the juncture. Furthermore, the method includes subtracting the second set of quality metrics from the corresponding quality metrics of the first set of quality metrics to calculate a third set of quality metrics representing the quality metrics of the second segment. Additionally, the method includes comparing the third set of quality metrics to a first set of segment qualities.
