    Zurich
    Telecom Discovery Builder framework
    Leverage a standardized Extract, Transform, Load (ETL) framework to streamline the processing and storage of telecom network data on the ServiceNow AI Platform.

    This reusable framework simplifies implementation by removing the need to manually build ETLs. It enables you to focus on connectivity logic while confirming consistent and reliable mapping of network elements such as equipment, cards, ports, LAGs, logical ports, and logical connections into predefined CMDB structures.

    Use Telecom Discovery Builder Framework to do the following:
    • Simplify data transformation tasks by duplicating the common ETL and configuring essential fields and settings for specific connector applications.
    • Deploy new Service Graph Connector (SGC) using existing ETLs to maintain consistent data transformation practices.
    • Help to ensure data integrity and support the automatic creation of TNI Entities through configured Before and After scripts.
    • The standardized CMDB/TNI data model enables ETL reusability across multiple connectors.
    • Allocate predefined storage locations for both physical and logical inventory elements.
    • Maintain consistent data model hierarchies across connectors to support unified network inventory management.
    • Improve Discovery SGC quality by providing an OOTB Data Source Validation tools.
    Identify and reconcile discrepancies
    Use enhanced discrepancy identification and reconciliation features to keep your discovery data accurate and up to date on the ServiceNow AI Platform. These features give you better control over detected changes and improve overall audit performance.
    • Identify attribute value mismatches during discovery, such as bandwidth changes on ports (for example, from 10 Mbps to 100 Mbps).
    • Display previous and current attribute values, enabling you to decide whether to accept the new value, retain the old one, or manually raise a remediation task.
    • Detect discrepancies in logical entities alongside physical entities for comprehensive discrepancy management for newly discovered logical network elements.
    • Generate audit results using filtering conditions—such as specific IP ranges, device vendors, or port types—to focus on relevant subsets of data and significantly enhance audit performance and usability.
    Fault Management: Events and alerts
    You can monitor your SD-WAN network health and resolve issues faster with automated alerts and event detection.
    • Detect and resolve SD-WAN network issues faster with automated alerts and event monitoring.

    • Configure customizable event rules to detect SD-WAN device issues in real time.
