Abstract
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.
