Nokia IP routing for mission-critical operations and high-performance enterprise networks
Explore Nokia's IP routing portfolio designed for large organizations operating mission-critical and business-critical networks. From harsh industrial environments to high-performance campus and metro architectures, the portfolio spans ruggedized edge routing to high-capacity core and interconnect solutions.
The portfolio delivers predictable performance, high availability, and end-to-end security, while simplifying operations through automation, streaming telemetry, and consistent workflows.
Key capabilities
Resilience for mission-critical operations
Fast convergence, deterministic performance, and ruggedized platform options for harsh and distributed environments.
End-to-end security
Segmentation and line-rate encryption (including MACsec) to protect critical services and reduce attack surfaces.
Scale without disruption
High-capacity routing across campus, metro, and data center environments, with a clear evolution path to higher speeds and densities.
Simplified operations at scale
Automation, telemetry, and model-driven workflows to accelerate deployment and reduce mean time to repair.
Who this is for
Enterprise (mission-critical operations and OT networks):
Network architects, engineering teams, and operations teams in industries where downtime and security incidents directly impact safety, service continuity, and revenue—such as utilities, railways, airports, manufacturing, and oil & gas.
Secondary audience includes technology and business leaders responsible for resilience, modernization, and cost optimization.
Large enterprise IT:
Campus and backbone network architects, engineers, and operations teams at universities, research institutions, and large enterprises that require high-throughput, low-latency routing to support AI, high-performance computing, and large-scale data movement without increasing operational complexity.
Platform selection guide
Use this guide to align your network requirements with the appropriate Nokia platform family:
| Where it sits in the network | Typical requirements | Suggested Nokia platform family |

| Access switching / service demarcation | Compact Ethernet access; ruggedized options; service demarcation; aggregation of local devices and uplinks | 7210 Service Access Switch (SAS) |
| Enterprise edge / regional aggregation | High availability; service scale; strong security; simple operations; growth to higher speeds | 7250 Interconnect Router (IXR) or 7730 Service Router Interconnect (SXR) |
| Campus/core routing | High throughput and scale; low latency; telemetry and automation; segmentation across domains | 7250 IXR or 7730 SXR |
| Data center and metro interconnect | High-capacity uplinks; simplified operations; encryption; optional IP/optical convergence | 7250 IXR / 7730 SXR |
| Cross-domain automation and visibility | Standardized provisioning; intent-based workflows; telemetry-driven operations | Nokia Network Services Platform (NSP) |
Key design questions
- What are your environmental and site constraints (indoor/outdoor, temperature, power, space)?
- What traffic types are most critical and what are the associated latency and jitter requirements?
- Do you require timing and synchronization at the edge or aggregation layer?
- What security and compliance requirements must be met (segmentation, encryption, threat mitigation)?
- What is your expected growth trajectory over the next 3–5 years?
- What level of automation, visibility, and operational maturity is required?
