From Reactive to Autonomous: How Red Hat OpenShift and NART OSS Are Modernizing Telecom Network Operations

As communications service providers (CSPs) navigate the demands of next-generation networks — 5G rollouts, cloud-native infrastructure, and ever-growing service complexity — the operations layer has become a critical bottleneck. Legacy operations support system (OSS) platforms, designed for a previous era, struggle to keep pace with the scale, speed, and automation that modern networks require.

TechNarts, a TM Forum member and a winner of multiple Outstanding Catalyst Award and an Excellence Award, built the NART OSS Suite precisely to address this gap. Now available as a certified cloud-native application in the Red Hat Ecosystem Catalog, NART OSS Suite can run natively on Red Hat OpenShift — bringing together a modern, cloud-native OSS platform and the industry’s most trusted hybrid cloud infrastructure.

The Complexity of Modern Network Operations

Today’s telecom networks are multi-vendor, multi-technology environments that span traditional transport, IP, and increasingly, cloud-native network functions. Operations teams are expected to deliver faster service, detect and resolve faults before they impact customers, and onboard new services through automated, software-defined workflows — all while managing costs.

Yet many CSPs still rely on siloed OSS tools: separate systems for network inventory, fault management, performance monitoring, and service fulfillment. Integration between these systems is manual, brittle, and expensive to maintain. The result is operational friction that delays service delivery, increases mean time to repair (MTTR), and limits the CSP’s ability to respond to market demands.

A modern OSS must be modular, application programming interface (API)-first, and cloud-native — capable of running at scale without the overhead of monolithic deployments.

A Unified OSS Platform, Built for Red Hat OpenShift

NART OSS Suite is an all-in-one, modular OSS platform that unifies network assurance, service orchestration, and resource management under a single architecture. Its three core pillars address the full lifecycle of network operations:

Resource Management provides a unified, technology-agnostic model of the network inventory. From physical infrastructure to logical services, CSPs maintain a single source of truth that drives configuration, planning, and impact analysis.

Network Assurance delivers real-time fault and performance management across multi-vendor, multi-technology domains. Rather than flooding NOC teams with raw alarms, NART OSS Suite correlates events, filters noise, and surfaces actionable insights — enabling proactive operations and measurably reduced MTTR.

Network Fulfillment & Orchestration automates end-to-end service activation and change management through model-driven workflows. New services are delivered faster, with fewer errors and without manual handoffs between teams.

All three modules run as cloud-native workloads on Red Hat OpenShift, taking full advantage of Kubernetes-native orchestration, automated lifecycle management, and the operational consistency that Red Hat OpenShift brings to hybrid cloud environments.

Why Red Hat OpenShift Matters for OSS

Running critical OSS applications on Red Hat OpenShift is not simply a deployment choice — it is an architectural decision that shapes how CSPs manage, scale, and evolve their operations infrastructure.

Red Hat OpenShift provides the cloud-native, unified application foundation that modern OSS demands. CSPs deploying NART OSS Suite on OpenShift benefit from automated rolling upgrades and rollback capabilities, reducing the risk and downtime associated with OSS maintenance. Horizontal scaling allows operations platforms to grow alongside the network without re-architecting. Built-in observability through Red Hat OpenShift’s integration with Prometheus and alerting frameworks complements NART OSS Suite’s own assurance capabilities.

For CSPs that already run network functions or business support systems (BSS)/IT workloads on Red Hat OpenShift, NART OSS Suite fits naturally into an existing platform — reducing the operational overhead of managing disparate infrastructure and enabling a unified approach to hybrid cloud governance.

Red Hat OpenShift also brings enhanced security controls, role-based access control (RBAC), and supply chain integrity through certified container images — critical considerations when the OSS platform has direct access to network configuration and operational data.

Accelerating Closed-Loop Automation

One of the most strategically important capabilities of the NART OSS Suite and Red Hat OpenShift combination is its readiness for closed-loop automation. In a closed-loop model, the network continuously monitors itself, detects anomalies, and triggers automated remediation — without waiting for human intervention.

NART OSS Suite provides the domain intelligence: the correlated fault data, the network model, and the fulfillment workflows. Red Hat OpenShift provides the infrastructure resilience and the platform-level orchestration to execute those workflows reliably at scale. Together, they form the operational backbone that moves CSPs from reactive ticket-driven operations toward intent-based, autonomous network management.

This is especially relevant as CSPs in growth markets — across Central Asia, the CIS region, and beyond — build out new infrastructure and need operations platforms that can scale alongside rapid network expansion, without proportional growth in operations headcount.

A Digital Twin for the Network — Including Transmission

One of the most distinctive capabilities in NART OSS Suite is its Digital Twin engine — a live, topology-aware virtual replica of the CSP’s physical network. While digital twins are increasingly discussed in telecommunications circles, most implementations remain narrow in scope: limited to radio access network (RAN) or IP layers. NART OSS Suite takes a broader and rarer approach by extending the digital twin down to the transmission layer.

Transmission networks — the microwave, optical, and synchronous digital hierarchy/plesiochronous digital hierarchy (SDH/PDH) infrastructure that carries traffic between sites — have historically been the hardest domain to model accurately. Yet they are often the most consequential: a single transmission link failure can cascade into service outages across an entire region. Despite this, transmission is frequently underrepresented in OSS platforms, managed through separate tools with limited integration into the broader network model.

NART OSS Suite changes this. By incorporating transmission topology into the unified network model, the platform enables CSPs to understand not just what failed, but what else is at risk — instantly.

Topology-aware impact analysis means that when a fault occurs anywhere in the network, NART OSS Suite immediately traverses the dependency graph to determine which services, customers, and downstream elements are affected. Because transmission links are modeled alongside IP routes and service paths — spanning microwave, wavelength division multiplexing (WDM) optical, and IP simultaneously — the analysis reflects the real propagation of impact through the network, not just the directly alarmed element. CSPs get the full picture in seconds, without manual investigation across disparate tools.

Simulation takes this further. Before making a change — planned maintenance, a topology modification, a new service activation — CSPs can run the proposed change through the digital twin to evaluate its impact before touching the live network. What services would be affected by taking this microwave link down for maintenance? Is there sufficient path diversity to protect a critical enterprise service? Would activating this new route create a single point of failure in the WDM layer? These questions, which previously required hours of expert analysis, can now be answered in the model before a single configuration change is made.

The result is a fundamentally more resilient approach to network operations. CSPs can design and verify protection strategies, stress-test their topology against hypothetical failure scenarios, and catch potential vulnerabilities before they become outages. Networks and services become, in the truest sense, resilient by design rather than by experience.

Running this capability on Red Hat OpenShift means the digital twin scales with the network. As new nodes, links, and services are added, the model updates and remains consistent — backed by Red Hat OpenShift’s persistent storage, API-driven integrations, and the platform resilience that CSPs rely on for production workloads.

Building the Next-Generation Operations Platform Together

The combination of NART OSS Suite and Red Hat OpenShift represents more than a technology integration — it reflects a shared vision for how telecommunications operations should evolve. Modular, cloud-native, automated, and built on open standards.

As networks grow more complex and service expectations continue to rise, CSPs need an OSS platform that can keep pace — not only managing what is happening now, but anticipating what could happen next. With NART OSS Suite running on Red Hat OpenShift, CSPs have a proven, scalable foundation for the journey to autonomous operations: unified assurance, model-driven fulfillment, and a transmission-inclusive digital twin that makes resilience something you engineer in, not patch in after the fact.
