Show full answer Show less ## Key Features Introduced Between Yokohama and Zurich * **Pattern-Based Direct Discovery (Yokohama):** Enables deep network discovery of physical network elements using CLI and SNMP protocols, supporting a variety of Cisco and Juniper routers and switches. It also provides a framework for custom MIB-based discovery and supports scheduled or quick discovery of standalone network elements. * **Nokia Altiplano SGC Integration (Yokohama and Zurich):** Supports discovery and management of physical GPON and logical network elements such as logical ports, LAGs, and connections. This integration allows storing logical elements in the CMDB for enhanced visibility and traceability across the network and uses a generic ETL framework to reduce development effort. * **Discrepancy Identification and Reconciliation (Yokohama and Zurich):** Identifies mismatches between discovered and inventoried data, including model mismatches, missing entities, relationship errors, and attribute value changes (e.g., bandwidth changes). Enhanced reconciliation features enable automated task creation and filtering options to improve audit performance and data accuracy. * **Fault Management for SD-WAN (Zurich):** Provides automated alerts and event detection to monitor SD-WAN network health and resolve issues quickly with customizable event rules for real-time detection of device problems. * **Service Graph Connectors for Cisco Meraki and Fortinet (Zurich):** Introduces centralized management of physical and logical network relationships, automated telecom-aware discovery, real-time CMDB synchronization, visual mapping, guided setup, and monitoring dashboards within the ServiceNow AI Platform. * **Granular Admin Roles (Zurich):** Allows developers and administrators to perform specific administrative configuration tasks in TSOM without requiring full administrative privileges, enhancing security and operational efficiency. * **Telecom Discovery Builder Framework (Zurich):** A standardized, reusable Extract, Transform, Load (ETL) framework that simplifies telecom data processing and storage, enabling consistent mapping of network elements into CMDB structures and improving data integrity with out-of-the-box validation tools. ## Key Changes and Deprecations * **Unified ETL for OLT and ONU (Zurich):** The previous separate ETLs for Optical Line Terminal (OLT) and Optical Network Unit (ONU) have been merged into a single unified ETL supporting both physical and logical data, with the older ETLs deprecated and phased out. * **Replacement of CMDB Compliance Audit (Zurich):** The Service Operation CMDB Compliance Audit has been deprecated and replaced by the more comprehensive Telecom Discrepancy Audit for improved audit capabilities. * **Enhanced Audit and Reconciliation Logic (Zurich):** Improved filtering and detection of discrepancies, including logical network elements, reduce unnecessary processing and improve audit usability and accuracy. ## Upgrade Considerations After upgrading from Yokohama to Zurich: * Review and validate any customized Identification Rule Engine (IRE) rules applied to interface cards, slots, and network interfaces to ensure continued functionality. * Leverage the new Telecom Discovery Builder Framework to streamline connector development and maintain consistent data transformation practices. * Utilize enhanced discrepancy identification features to maintain accurate and up-to-date network discovery data. ## Activation and Availability TSOM applications and plugins for both Yokohama and Zurich releases are available through the ServiceNow Store. Customers should request installation via the ServiceNow Store, where they can also access version history and cumulative release notes. ## Additional Notes * There are no additional browser, localization, or accessibility requirement changes between Yokohama and Zurich. * No features were removed in the Zurich release.
