Summary of Visualization of Network Topology
The network topology in the Telecommunications Network Inventory application provides a visual representation of network elements, including nodes (equipment), edges (connections), and termination points (interfaces). This visualization can take various structures such as ring, tree, mesh, star, or bus. It plays a crucial role in planning network expansions, monitoring performance, and troubleshooting faults.

Key Features
- Network Viewer Window: Access the topology through the Network Viewer, which includes a search box, map pane, and details pane.
- Search and Filter: Use the search box to select and visualize multiple topologies simultaneously, with advanced filtering options based on set conditions.
- Map Pane: Displays the selected topology, allowing actions such as highlighting connections, refreshing the view, fitting to screen, and zooming in/out.
- Details Pane: Shows related information about the selected topology, node, or connection. You can view additional details and navigate to corresponding CI records.
Key Outcomes
By utilizing the network topology visualization, ServiceNow customers can effectively plan and manage their network infrastructure. This tool enables better insight into network organization and connectivity, facilitating proactive performance monitoring and efficient troubleshooting of issues.
The topology in the Telecommunications Network Inventory application graphically displays how the different elements in a network such as equipment, connections, and interfaces are organized and connected to one another. By using a topology, you get a bird's eye view to the network.
Overview
The network topology is a visual representation of the network elements such as nodes (equipment), edges (connections), and termination points (interfaces), and how they’re organized and connected to one another. A topology can be a ring, tree, mesh, star, or bus in structure. A topology enables you to plan the network expansions, monitor the network performance, and troubleshoot the faults occurring in the network.
The following example shows a topology in the Telecommunications Network Inventory application.
- The search box and advanced filter enable you to select the topology.
- The map pane shows the network topology.
- Details pane on the right shows related information of the topology according to the current selections.
Search box
Use the search box to select the topology that you want to visualize. You can select multiple topologies at a time. The advanced filter option enables you to filter the topologies based on the conditions that you set.
Map pane
The map pane shows the topology that you selected in the search box. You can view many topologies in the map pane at a time. The map pane also shows the name of each element in the topology.
- Point to a node to highlight the connections that are associated with the node.
- Select one among the topologies to highlight the elements associated with it.
- Select the refresh icon (
) to reload the map and return it to its initial view. - Select the fit to screen icon (
) to adjust the topology to the size of the map pane. - Use the zoom controls to zoom in and out of the map.
Details pane
The details pane shows the related information about the topology, node, or connection that you’re selected. You can select the info icon (
) to view the details pane. Initially the details pane shows the related information about the topology record. If you select a node, then the details pane shows the related information about that node. If you select an
empty space on the map pane, the details pane shows related information about the topologies that are opened.
You can also select View Details in the details pane to redirect to the corresponding CI record.
Access
- Navigate to .
- Select the network viewer icon (
).
