Abstract
The present invention relates to methods and node entities for enabling active measurement for evaluating network performance in a network comprising a logical tree structure 10 representing at least one service. Said service is provided through a set of links from an initial node in an upper level of the tree structure to a node in a lower level of said tree structure. Each node of the tree structure is configured to perform active measurement of link characteristics. One object of the present invention is to provide a method for minimizing the data overhead introduced in a data network during measuring of estimates of the data network performance. By aggregating measurement results of estimated and measured link characteristics in the nodes of said tree structure and propagating the aggregated results and store the aggregated results in the nodes.
