Abstract

The present invention relates to a graphical user interface (GUI) for displaying historical and current performance information for a route in a communications network, the route having several paths between two end points. Performance data from the network is collected and processed to generate route and path performance data. The processed data is stored in a database. The GUI is embodied in a network management device which draws upon information stored in the database. In a preferred embodiment, the GUI displays a route panel showing the structure of the route, a timebar showing the time period for which information is displayed, a paths panel showing information about each path in a tabular format, a selected paths panel showing information about selected paths in a tabular format, and a performance panel showing performance data in a graph.
