Abstract:
A method for characterizing network segment quality for a segment transmitting messages from a first endpoint to a second endpoint on a network, the network having first and second segments connected to the first and second endpoints respectively and to each other at a juncture, the method comprising:receiving messages transmitted between the first and second endpoints at the juncture, the messages including a first set of quality metrics for message transmission from the first to second endpoint for both the first and second segments and including a second set of quality metrics for message transmission from the first endpoint to the juncture; 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; and comparing the third set of quality metrics to a first set of segment qualities to characterize the quality of the second segment.
