After more than a decade building advanced automation at Deutsche Telekom, we've converged on a service architecture for Cisco NSO that brings together asynchronous operations, closed-loop automation, brownfield readiness and more into a cohesive, modular design. It's the architecture we always wanted - and now it's real.
This talk presents the core principles behind that architecture: declarative service inputs, layered CFS/RFS design, device-oriented RFS deployment, nano-services for staged processing, and built-in support for service discovery. These patterns have been validated across multiple DT projects - and more recently, proven again in production at GleSYS, using the same architecture and codebase.
To share this work, we’ve created RESPNET: a complete implementation for a realistic service provider network using Cisco NSO that embodies the architecture in a working, open source codebase. Use it to explore the ideas, or as a foundation for automating your own network.
Curious to go deeper? Join our Master Service Design sessions later in the conference, where we’ll explore the practical design patterns, challenges, and lessons learned behind this architecture.
