iMaster NCE-Fabric provides northbound open capabilities to design, verify, and release services involved in Day 0, Day 1, and Day N work orders in advance. It interconnects with third-party work order systems to directly invoke scenario-specific APIs generated by the runbook, and supports one-click processing of services such as switch and server capacity expansion in work orders.

• The runbook function supports the following capabilities
• Provides GUI-based network service orchestration, masking complex internal invoking processes.
• Supports service orchestration, configuration verification, provisioning, and rollback based on design-state and provision-state configuration libraries, without affecting services running on the live network.
• Flexibly defines NaaS scenarios and provides service-oriented networking across the full lifecycle.
• Supports collaborative deployment on cross-cloud and cross-DC heterogeneous networks, as well as unified O&M and management of multi-vendor networks and devices.
