Advanced management of AMS (Application Management Services) in the Cisco NSO Order Management Node domain

Exprivia’s experience alongside Open Fiber

Open Fiber was founded with a clear mission: to reduce the digital divide and connect Italy through an FTTH (Fiber To The Home) fiber optic network, ensuring citizens, businesses, and institutions equitable and advanced access to digital services. Open Fiber is building the largest pure fiber optic infrastructure in the country, with a wholesale-only business model that offers all Operators equal access conditions, fostering competition and expanding choice for end users.

The Customer’s Needs

Open Fiber uses Cisco NSO as a strategic platform for the orchestration and automation of network services.

The complexity of the application ecosystem — which includes several integrated modules such as NSOSRI, Inventory, Provisioning Systems, and other external components — makes accurate and continuous management of operational activities essential.

In this context, Open Fiber needed to rely on a qualified technology partner capable of providing an Application Management service able to ensure:

• operational continuity and system stability;
• service quality and constant oversight of the platforms;
• timely interventions for anomaly resolution and process optimization.

The objective was twofold: on the one hand, to minimize service disruptions in the production environment; on the other, to maintain proactive and integrated control over the entire application lifecycle of NSO and its associated modules, through analysis, troubleshooting, and monitoring activities, without impacting the services provided.

The Exprivia Solution

Exprivia took charge of the Service in 2024, providing a dedicated Application Management Services (AMS) team highly specialized in Cisco NSO, structured to manage the following activities in an integrated manner:

• Analysis and resolution of application faults through system logs, DB queries, and transactional network analysis.
• Monitoring and proactive management of failed orders and batch/online transactions.
• Configurations and data remediation on CDB and NSOSRI.
• Support for Open Fiber’s technical functions (Technical Support, Engineering, Delivery) to ensure functional and operational alignment.
• Complete management of AMS tickets, both reactive and proactive, through the Open Fiber ticketing system.

Results

The Exprivia AMS service has made it possible to increase efficiency in managing the NSO application lifecycle, improve system stability and reliability, reduce the average time required to resolve anomalies, and optimize collaboration among operational teams. Thanks to constant coordination and an ITIL-based approach, service continuity has been ensured even during nighttime releases and weekend activities.

In summary

The AMS model implemented by Exprivia for Open Fiber represents a concrete example of proactive, value-oriented management in the field of network automation services. Thanks to its expertise in Cisco NSO and its ability to integrate processes, technology, and people, Exprivia continues to support Open Fiber on its path toward an increasingly intelligent, resilient, and automated network.
