Network design repositories

The network’s source of truth as text, checked against reality and protected by intents.

Keep what your network should be (sites, devices, ports, links, circuits and the ducts they share) in a repository, compare it with what the devices report, write intents it must keep, test what-if failures, and let no pull request break a promise. Export it as a lab, and certify every change.

Get started with network design repositories

A guided path from "what is a network design repository?" to certified changes: the network's source of truth as text, compared with reality, protected by intents in every pull request, tested with what-if failures and run as a lab. Pictures first, every step explained.

⏱ About 35 minutes◔ From zero to advanced
  1. Stage 1Understand
    1. What a network design repository is
    2. Why drawings lie
    3. Design, reality, prediction
  2. Stage 2Start
    1. Create the repository
    2. Your first design
    3. Code or canvas, your choice
  3. Stage 3Check it
    1. See it four ways
    2. Design and reality
    3. Intents: promises the design must keep
    4. Pull requests that can't break a promise
  4. Stage 4Go further
    1. What if, and the link that would help
    2. Availability, capacity and disjoint paths
    3. History, and help from an AI
    4. Run it as a lab
    5. Certificates, and where to go next

What you can do

  • Import a running network as a design
  • Edit the design as code or on a canvas
  • See where the design and the network disagree
  • Block changes that break redundancy you promised
  • Find the link that would remove a single point of failure

Network design repository

The network design as text in a repository, reviewed like code, compared with what the devices really say, and tested: intents the design must keep, what-if failures, and a merge gate.
