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

摘要

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.

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 measurement tool to be used in a measurement session for evaluation of the link; selecting a mathematical model based on the indication of the measurement tool; generating a set of measurement values by executing the measurement session while using the measurement tool according to the indication of the 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 values and the selected mathematical model; and identifying at least one of the first and second segments based on the first and second values.
