METHOD AND NETWORK ENTITY FOR EVALUATING A LINK BETWEEN A FIRST NETWORK NODE AND A SECOND NETWORK NODE

A method and a network entity for evaluating a link between a first and a second network node are disclosed. The link is configured to carry data packets between the network nodes via a third network node. The link comprises a first segment and a second segment. The network entity obtains an indication of a measurement tool to be used in a measurement session for evaluation of the link. The network entity selects a mathematical model based on the indication. The network entity generates measurement values by executing the measurement session. The network entity determines a first and a second value relating to lost data packets of the first and second segments, respectively, based on the measurement values and the selected mathematical model. The network entity identifies at least one of the first and second segments based the first and second values.
