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.

Multi-panel route monitoring graphical user interface, system and method

The invention provides a new cost-effective and efficient framework for network management of telecommunications networks by monitoring the network-level concepts of routes and paths. The invention is embodied in a route and path management (RPM) system which includes a data collector for collecting data from the individual network elements, a management server for processing the routing data collected into manageable route and path objects and a graphical unit interface (GUI) for allowing a user to manage and monitor routes and paths in the IP network. By monitoring routes and paths, the RPM provides network managers with the added capability of troubleshooting, performance monitoring, service level planning and provisioning packet forwarding paths between any source-destination endpoints in a network.

Routes and paths management

A network management method and system for managing a network in which routes between pairs of end points take different paths is provided. To begin, device level status and performance information is collected from the network and transformed into path and route information. Next, from the path and route information parameters which characterize the state of each of the routes are computed. Next, the parameters of each of the routes are displayed graphically. This allows a user to obtain a quick visual identification of the state of all of the routes in the network individually and in relation to one another. The invention also provides a network management graphical user interface method in which a 3-D representation of three axes is displayed. Each axis pertaining to a respective one of three route parameters. On these three axes, for each route a parameter point representing the routes parameters is displayed as a function of time. An instantaneous direction and rate of change for each parameter is computed. Each parameter point is displayed in the form of a cone having a central axis pointing in the instantaneous direction of the parameter point, and which has a length which is proportional to the rate of change of the corresponding parameter point.
