Nefeli for Service Providers

Nefeli Networks was created to streamline Network Function Virtualization (NFV) by implementing a commercial version of the “Lean NFV” architecture developed at the NetSys lab at UC Berkeley.

In its original form, NFV was part of the software defined networking movement that aimed to shift away from the customized hardware previously required to upgrade network capabilities. The vision was to provide carriers, like telcos and other service providers, with greater agility when implementing network functions like load balancers and firewalls.


Accelerating Innovation with Lean NFV

Given the anemic adoption of NFV, the team at the UC Berkeley NetSys lab sought to drastically simplify the complexity of implementing NFV. The result was Lean NFV which was launched at the Open Networking Summit in April 2019. Additional information about Lean NFV can be found at

Nefeli Networks turned the Lean NFV vision into commercial code to deliver high availability, dashboards, monitoring, alerts and other operational capabilities needed to run VNFs.

A core challenge with implementing the original NFV infrastructure was the complicated pairing of APIs between individual Virtual Network Functions (VNFs) which vary by orchestrator and vendor. The core breakthrough with Lean NFV is replacing the APIs with a single “key value store,” a shared information repository that can hold information that VNFs need to exchange, such as configuration, software state, analytics and internal status for snapshotting.
