Abstract: A method, apparatus, and computer program for network analysis are provided. The method comprises: outputting, in a network analysis tool, display content comprising a layout of the communication network comprising network elements in the form of a plurality of network nodes and a plurality of communication interfaces connecting the plurality of network nodes, the display content further comprising compressed application information associated with at least one of the network elements, wherein the compressed application information indicates what type of user application data traffic is currently transferred through said at least one of the network elements; receiving an input to select at least one of the displayed network elements; and outputting, as a response to the input, detailed application information of the selected at least one of the displayed network elements.

Abstract: An arrangement and method for analysing the data transferred in communications networks. The fact that though the amount of user plane traffic and data is increasing fast, the amount of signalling traffic is hardly increasing at all, is utilised. In the present system the analysis of the user plane and the control plane is done separately in user plane analysis appliance (206) and protocol analyser (204). The separate analysis results are then combined by certain criteria and the combined data is shown. An at least nearly real-time network data analysis is possible also in the networks with high speed traffic.
