Abstract
Methods and apparatus for determining and using link performance measures (D, C) in respect of communication links () in a cata communication network () are disclosed, where the network comprises a plurality of data-forwarding nodes () each capable of forwarding data along a plurality of communication links (). Link performance measures (D, C) are determined in dependence on end-to-end path performance measures (Es,u) received in respect of a plurality of end-to-end paths having at least one link in common, and on the basis of route information (Rs,u) identifying the links of which those end-to-end paths are comprised. Methods are disclosed for using link performance measures in relation to decisions regarding the routing and/or re-routing of data in a network, and in relation to determining measures indicative of expected quality of experience in respect of data traversing end-to-end paths across a network.
