Ribbon IP rNOS: Network Operating System for Ribbon's Routers

Industry-proven NOS trusted in service provider and mission-critical networks.

Request an NPT Quote

Ribbon IP rNOS is a modern network operating system designed to power scalable, secure, high-performance IP routing across service provider and mission-critical networks. Built for flexibility and automation, Ribbon IP rNOS decouples software from hardware, enabling operators to deploy, scale, and manage IP networks with greater speed, efficiency, and control.

The Ribbon IP rNOS is foundational to Ribbon's NPT router portfolio:

  • Powers all of Ribbon NPT routing platforms
  • Integrates with open coherent and pluggable optics environments
  • Enables IP over DWDM and converged IP-optical architectures
  • Supports end-to-end automation with Ribbon management tools

Designed for Modern Network Use Cases

Service Providers

Ribbon IP rNOS gives service providers the modern IP access and aggregation capabilities they need to deliver scalable, reliable and service-rich networks. Running across the entire Ribbon NPT IP routing portfolio, it supports L2 VPN, L3 VPN and EVPN services, while also enabling operators to continue supporting legacy TDM services on modern routers through industry-leading circuit emulation services.

 

Utilities and Energy

For utility networks, Ribbon IP rNOS provides the deterministic, secure and resilient packet transport needed to modernise operational technology communications without disrupting critical services. Running across Ribbon NPT platforms, it supports SCADA, teleprotection, substation automation, timing and legacy TDM applications alongside modern Ethernet and IP services, helping utilities migrate from SDH/SONET to packet-based networks at their own pace. With multi-stack MPLS, circuit emulation, advanced timing and service segregation capabilities, IP rNOS helps utilities protect mission-critical traffic, improve network visibility and support always-on grid operations.

 

Transport and Rail

For rail and transportation networks, Ribbon IP rNOS delivers the deterministic, resilient and secure packet transport needed to support always-on operational communications across stations, depots, trackside sites and control centres. Running across Ribbon NPT platforms, it supports signalling, interlocking, operational voice, SCADA, CCTV, passenger information, Wi-Fi backhaul and legacy TDM services alongside modern Ethernet and IP applications. With multi-stack MPLS, circuit emulation, advanced timing and service segregation capabilities, IP rNOS helps transport operators modernise SDH/SONET networks, support IT and OT convergence, and build a scalable foundation for FRMCS, smart mobility and future rail services.

 

Defense and Government

Ribbon IP rNOS supports the always-on, never-fail communications required by defence and government networks. It delivers secure, hardened, high-capacity and low-latency deterministic IP transport to collect and distribute real-time information from sensors, command systems, surveillance, radar and edge devices across distributed mission environments. With FlexE support, operators can create separated network slices over shared infrastructure, helping protect critical traffic, maintain service isolation and support mission-specific connectivity requirements in a shared communications environment.
