Advanced Fabrics documentation

Build network fabrics you can understand. Advanced Fabrics (AdvFab) defines portable APIs to observe, compose, and change cloud-native network fabrics across replaceable providers.

Project status

AdvFab is under active development. The 1.0 release gates are still open. This is an independent open source project and is not a CNCF project.

Start here

  • Quick start evaluate the current source and verify what you run.
  • Concepts learn topology, observation, evidence, configuration, and providers.
  • Architecture see how contracts and implementations fit together.
  • Security and safety understand the boundary around network changes.
  • Specifications find normative material and conformance work.
  • Community follow governance, releases, and contribution.

Design principles

  • API first. Machine-readable contracts are versioned separately from implementations.
  • Observe first. Missing evidence remains unknown; the system does not invent healthy observations.
  • Replaceable providers. The core contract does not depend on one CNI, router, or metrics backend.
  • Public decisions. AFEPs record standards changes, while conformance claims bind to exact artifacts.
