    Summary of Visualize circuits

    The network diagram feature in the Telecommunications Network Inventory application provides a graphical, hierarchical map of logical connections and their underlying connection elements. It enables ServiceNow customers to visually explore the structure and details of logical connections, including their revisions and protection paths, offering a comprehensive overview of circuit connectivity and redundancy.

    Key Features

    • Hierarchical Map Display: Visualizes logical connections starting from the home node CI, expandable up to three levels to reveal all underlying connection elements.
    • Protection Paths: Displays alternative routes for logical connections to ensure network resilience in case of primary path failures.
    • Interactive Map Pane: Allows users to expand/collapse nodes, view connection revisions, inspect protection paths, and control zoom levels for detailed circuit analysis.
    • Details Pane: Shows contextual information about the selected node in the map pane, with options to view detailed CI forms for deeper inspection.
    • Access through Workspace: Accessible via the Network Inventory Workspace by opening a logical connection record and selecting 'View connection' to launch the network diagram.

    Key Outcomes

    • Provides a detailed, visual representation of logical connections and their components, aiding in network management and troubleshooting.
    • Enables quick identification of protection paths, improving understanding of network redundancy and failover mechanisms.
    • Facilitates easy navigation through complex network hierarchies, enhancing operational efficiency for network inventory management.
    • Integrates directly with CI forms for seamless access to detailed configuration and status information.

    The network diagram in the Telecommunications Network Inventory application graphically displays a hierarchical map of the logical connection and its underlying connection elements. You can use the network diagram to get a detailed overview of the logical connection.

    The network diagram graphically displays a circuit of the logical connection elements, and the details of each element. It provides a detailed overview of a logical connection and how the various elements are connected to each other. You can view the following by using the network diagram:
    • Logical connection and all the underlying connection elements.
    • Revision of the logical connection and all underlying connection elements.
    • Protection paths of the logical connection.

    A protection path of a logical connection refers to an alternative route in case the primary path (logical connection) fails or experiences significant issues.

    The following example shows a network diagram in the Telecommunications Network Inventory application.
    Figure 1. Example for a network diagram
    View of a network diagram with map pane, details pane, and zoom options.
    A network diagram contains two panels:
    • The map pane shows the map for a selected logical connection, revision of the logical connection, and protection path.
    • The details pane shows related information of the logical connection according to the current selections.

    To learn more about how to use the network diagram, see Network diagram.

    Map pane

    The map shows all logical connection elements in the hierarchy starting with the home node CI, up to the specified level. You can expand the hierarchy levels up to three levels and view all the underlying connections. You can only expand connections that have connection elements underneath them.

    You can perform the following actions in the map pane:
    • Expand and collapse the nodes and view all the underlying connections.
    • View the revision of the logical connection.
    • View the protection paths of the logical connection.
    • Use the zoom controls to zoom in and out of the map.

    To learn more, see View the details of a network diagram.

    Details pane

    The details pane shows the related information about the logical connection elements in a network diagram. If a node is selected in the map pane, the details pane shows the related information for that node. For example, if you select a logical connection node on the network diagram, then the details pane shows all the details related to that logical connection.

    You can perform the following actions in the details pane:
    • Select the info icon (Info Icon.) to open the details pane.
    • Select more options icon (More Options Icon.) in the details pane and then select View Details to redirect to the corresponding CI form.

    Access

    You can access the network diagram in the Telecommunications Network Inventory Workspace as follows:
    1. Navigate to Workspaces > Network Inventory Workspace.
    2. Open the desired logical connection record.
    3. Select View connection to open the network diagram for the respective logical connection.
