1. A method for evaluating a link between a first network node and a second network node, wherein the link is configured to carry data packets between the first and second network nodes via at least one third network node, wherein the link comprises at least a first segment configured to carry data packets between the first and third network nodes and a second segment configured to carry data packets between the second and third network nodes, the method comprising:

  • obtaining an indication of a selected measurement tool, selected from a plurality of measurement tools, to be used in a measurement session for evaluation of the link;

    selecting a mathematical model, from a plurality of mathematical models, based on the indication of the selected measurement tool;

    obtaining a set of measurement results by executing the measurement session while using the selected measurement tool according to the indication of the selected measurement tool;

    determining a first and a second value relating to lost data packets of the first and second segments, respectively, based on the set of measurement results and the selected mathematical model; and

    determining whether at least one of the first and second segments is degraded or available based on the first and second values.
