The path to scalable, sustainable networking

As organizations look to modernize and simplify their network infrastructure, a converged optical and routing architecture has emerged as a strategic priority. By integrating IP routing and optical layers, organizations can gain significant improvements in cost efficiency, operational simplicity and scalability.

Maturing in this space means moving from siloed IP and optical domains to unified, software-driven platforms that reduce hardware footprint, streamline management and respond dynamically to changing traffic patterns. The result is a network that's not only more agile and sustainable — but also better positioned to support future growth and innovation.

Our Converged Optical and Routing Maturity Model outlines the key stages of adoption, helping organizations assess where they are today and what it takes to advance. From basic integration to autonomous operations, each level builds on the last to unlock greater value, resilience and control.

Our model

WWT developed the Converged Optical and Routing Maturity Model to help organizations assess their current state and chart a path forward. It outlines key stages of adoption — from siloed infrastructure to fully autonomous operations — and details the capabilities gained at each level.

The model isn't about reaching the highest level as quickly as possible. It's about aligning network capabilities with what matters most — whether that's improving agility, simplifying IT operations or increasing service reliability. If Level 3 supports those goals and delivers the outcomes your organization needs, that's success. If you're at Level 2 and see a gap between your current capabilities and desired outcomes, that's not a shortcoming — it's an opportunity to evolve at a pace that fits your priorities.

No matter where you begin, remember that progress is marked by incremental, outcome-driven improvements.

Level definitions

0: Siloed: IP and optical domains operate independently, leading to fragmented operations and slower service delivery.

1: Basic: Early convergence starts with pluggable optics, supporting point-to-point IP-over-DWDM connectivity and initial cross-team collaboration.

2: Defined: Integrated platforms and shared processes improve planning, visibility and responsiveness.

3: Advanced: Modular, pluggable infrastructure creates a more flexible, software-controlled network with deeper visibility.

4: Optimized: Networks are provisioned, monitored, and adjusted automatically across IP and optical layers.

5: Autonomous: A fully self-optimizing network adapts to application and traffic demands across IP and optical layers in real time.
