Lean NFV 

A pragmatic approach to making NFV deployable


Lean NFV is an approach that mitigates the complexity of deploying NFV, introduced last year by Sylvia Ratnasamy (UC Berkeley and Nefeli Networks), Scott Shenker (UC Berkeley and Nefeli Networks) and Constantine Polychronopoulous (VMware) at the Linux Foundation’s Open Networking Summit 2019.

All new technologies have growing pains, particularly those that promise revolutionary change, so the community has waited patiently for Network Function Virtualization (NFV) solutions to mature. However, the foundational NFV white paper is now over six years old, yet the promise of NFV remains largely unfulfilled, so it is time for a frank reassessment of our past efforts. To that end, this document describes why our efforts have failed, and then describes a new approach called Lean NFV that gives VNF vendors, orchestration developers, and network operators a clear path forward towards a more interoperable and innovative future for NFV.

Frequently Asked Questions

What is Lean NFV?

Lean NFV is an open architecture approach that gives VNF vendors, orchestration developers, and network operators a simpler way to approach and deploy NFV. It is designed to be minimally invasive and can integrate with existing NFV infrastructure platforms as well as ongoing orchestration initiatives.

Why Lean NFV?

It has been over six years since the publication of the foundational NFV white paper. However, the promise of NFV has still be unfulfilled. We believe that alternative approaches should be discussed and considered to help accelerate NFV adoption.

Who is Lean NFV?

Lean NFV is made up of industry veterans who have been closely involved with virtualization efforts in telco and cloud data centers. We are a collection of community members who have come together to help improve the success of NFV. The list of signatories appears in the Lean NFV white paper.
