    摘要： A method for inferring component parameter values for components in a network is disclosed. The components comprise at least one of network nodes or network links and the method comprises identifying a plurality of paths through the network (100), measuring values of a path parameter for identified paths (410), generating a set of constraints by expressing individual measured path parameter values as a function of component parameter values of the components in the path associated with the measured path parameter value (420a), and generating an estimate of the component parameter values by solving an optimisation problem defined by the generated constraints (420b). The method further comprises, for individual components in the identified paths, matching the generated estimates of the component parameter value to a statistical distribution describing a behaviour of the component parameter (430a), identifying a ratio of central moments of the statistical distribution that demonstrates a sensitivity to noise below a threshold value (430b), and calculating an inferred value of the component parameter from the identified ratio of central moments (430c).

    摘要： A method of monitoring performance of a network using network tomography comprises obtaining (102) information indicative of topology of the network and computing (104) a plurality of paths for monitoring the network. Further the method comprises instructing (110) source nodes of the computed paths to send probing packets towards destination nodes of the computed paths, wherein said probing packets undergo segment routing in said network and instructing (114) the destination nodes of the computed paths to carry out network performance measurements based on probing packets received by the destination nodes. Finally the method comprises receiving (116) the performance measurements from the destination nodes and inferring (118) information about performance of nodes in the network using network tomography, wherein the inference process includes correlating the performance measurements of the computed paths.

    摘要： A method (50) of selecting a set of probing paths in a network for network tomography. The method comprises generating (52) possible probing paths (P1). The method further comprises determining (53) if the possible probing paths are linearly independent from probing paths already selected for the set of probing paths, in an order of an increasing cost or distance of the possible probing paths. The method further comprises selecting (55) a said possible probing path for the set of probing paths only if the possible probing path is linearly independent from probing paths already selected.
